Chaenactis artemisiifolia is a robust annual herb producing an erect stem occasionally as tall as two meters-6 feet but usually under one meter-3 feet in height. There is a basal rosette of leaves and sparse leaves along the stem. The leaves are up to about 15 centimeters (6 inches) or more in length and they are divided into many lobes which are further subdivided into smaller, lacy lobes. The leaves and stem are lightly woolly; older plants have thinner coats of hair.
The stem branches about midway up and bears several flower heads in a wide open inflorescence. Each head is a hairy hemispheric cup of sharp-tipped phyllaries which can be up to a centimeter long. The flower heads are discoid, containing only disc florets, but some of them are flat enough to resemble ray florets or petals. The florets are white to pink. The anthers and curly styles protrude far from each floret, making the flower head look like a pincushion. The fruit is a compressed achene about half a centimeter long with no pappus.


Erythrodiplax minuscula, the little blue dragonlet, is a species of skimmer in the dragonfly family Libellulidae. It is found in North America.
The IUCN conservation status of Erythrodiplax minuscula is "LC", least concern, with no immediate threat to the species' survival. The population is stable. The IUCN status was reviewed in 2017.


In New Zealand it is listed on the National Pest Plant Accord which identifies pest plants that are prohibited from commercial propagation and distribution. In Bermuda it is listed as a Category 1 Invasive Plant by the Department of Environment and Natural Resources. Within the United States, four southern states (Alabama, Arkansas, South Carolina, and Texas) have all placed this plant on their individual noxious weed lists. It is a noxious weed in New South Wales, Australia, where it should be controlled according to the measures specified in a management program published by the local control authority and it must not be sold in some local government areas in the state.


The 1989 book records that “The root is diuretic and demulcent. It is mucilaginous, but has a nauseous taste, and is used to treat rheumatism. Sanskrit writers describe the root as emetic, laxative, stomachic, and rubefacient; they prescribe it in rheumatism, nervous diseases, piles, etc. The leaves are used in amenorrhoea. Rheede says that on the Malabar coast the leaves are administrated for pulmonic complaints. It is also used in homeopathy to treat eczematic skin. For this purpose, a mother tincture is made from the flowering parts of the plant. This is also processed into creams and ointments. The green parts of the plant are eaten as vegetables.
According to Ainslie, the root is considered laxative, and is given in dosages of half a cupful twice daily. “It would appear that in rheumatism the Hindus [sic.] administer the leaves internally rubbed up with castor-oil, and also apply a paste, made with them, externally; a similar external application is used to reduce swellings and tumours of various kinds.” (Dymock.)
Its ingredients include triterpene saponins, halicaric acid, catechin tannins, terpenes, phytosterols, flavonoids and quebrachitol.


Cardiospermum halicacabum, known as the lesser balloon vine, balloon plant or love in a puff, is a climbing plant widely distributed across tropical and subtropical areas of Africa, Australia, and North America that is often found as a weed along roads and rivers.


The balloon vine is a strongly overgrown, perennial herbaceous climbing plant that can even become lignified at the base. Growing over 10 meters high, it can bloom at a height of around 25 cm. The slender, grooved stems are hairy bald to sparsely downy.
The 5 to 6 cm long, triangular foliage leaves distributed on the stem are divided into a petiole and pinnate leaf blade. The petiole is (0.5 to) 1.5 to 3.5 cm long and the rachis is 0.4 to 2 cm long. The opposite leaflets are 1 to 2 cm long and the terminal leaflets are 4 to 6 cm long. The leaf margins are serrated. The stipules are reduced to tiny, early-falling scales. On the side of a 5 to 9 cm long, sparsely downy hairy inflorescence stem, there are two 1 mm long bracts, two circularly rolled tendrils and three to seven flowers in a zymous inflorescence.


Ribes roezlii is native to many of the mountain ranges of California, its distribution extending east into Nevada and north into Oregon. Its habitat includes chaparral, woodlands, and forested areas.


Ribes roezlii is a spiny shrub growing erect to a maximum height around 1.2 metres (3.9 ft). The hairless to hairy or woolly leaves are up to 2.5 centimeters (1 inch) long and divided into 3 or 5 rounded, toothed lobes.
The inflorescence is a solitary flower or raceme of 2 or 3 small wind-pollinated flowers hanging pendent from the branches. Each flower has five reflexed red-purple sepals around a tube-shaped ring of smaller white or pinkish petals, the stamens and stigmas protruding.
The fruit is a red or purple berry up to 2.5 centimeters long which is covered in thick, long spines.  Among other currants and gooseberries with overlapping ranges, such as mountain gooseberry (Ribes montigenum) or wax currant (Ribes cereum), the sierra gooseberry is especially notable for the large size and extreme spininess of its berries, and for the absence of a noticeable dried flower remnant at the end of the fruit.
Seeds are dispersed by running water and by animals that eat the fruits, such as American black bears. The foliage is an important food source for mule deer and bighorn sheep, and the fruits are a common food for fox sparrows living in its range. The berries can be eaten by humans in an emergency, but are unpalatable.


Helminthotheca echioides, known as bristly (or prickly) oxtongue, is a stiff annual or biennial herb native to Europe and North Africa. It was traditionally used as an antihelminthic treatment.


Helminthotheca echioides may grow up to 90 cm (35 in) tall, with a thick, furrowed stem and spreading branches. The leaves are 10–20 cm (4–8 in) long, oblanceolate with a short petiole. The leaves, branches and stem are all covered in thick bristles. The inflorescences are 2–3.5 cm (0.8–1.4 in) wide and subtended by between 3 and 5 large ovate-cordate involucral bracts. These large bracts are the defining feature of the genus Helminthotheca.
A number of infraspecific taxa are recognised, varying in their leaf shape.


P. chinensis collects nectar and honeydew from flowers. The wasp preys on invertebrates, preferring larvae and caterpillars of lepidopteran insects (moths and butterflies) for protein resources, but may also feed on marine invertebrates or fish carrion when the opportunity arises. Asian paper wasps also feed on the larvae of other conspecific females. Larval saliva is an important nutrient resource for adult Asian paper wasps. This contains a high concentration of free amino acids, 50 times that of floral nectars, and is nutritionally analogous to nectar.


The Asian paper wasp frequently constructs nests on man-made structures including houses and buildings. It will also build nests on trees or bushes, usually on branches, but sometimes on leaves as well. P. chinensis prefers to colonize urban habitats, but nests have also been recorded near forest clearings. They sometimes build their nests in dense shrubs, making them difficult to locate. Large populations usually develop in warm, lowland areas with open habitat such as shrublands, swamps and meadows.
The paper wasp is native to East Asia. It has been recorded in China, Japan, Korea and Mongolia. The subspecies
P. chinensis antennalis is invasive in New Zealand. It is widespread in the North Island and the northern South Island and competes with native species for food,  It has since been recorded in Norfolk Island and New South Wales. At least two independent invasion events, linked to Kanto and Kyushu, Japan, have been proposed as sources of the New Zealand wasps.  The Asian paper wasp was first recorded in New Zealand in 1979, in Kohimarama and the Whangaparaoa Peninsula. It remained confined to these areas of Auckland until 1984, when it began appearing in inner city areas and western suburbs.


Among the Zuni people, the powdered root mixed with flour, made into a bread and used to decrease appetite. An infusion of the root is taken and rubbed on the abdomen of hungry adults and children. An infusion of the powdered root is taken by adults or children after overeating.


Mirabilis multiflora is a species of flowering plant in the four o'clock family known by the common name Colorado four o'clock that is native to the southwestern United States from California to Colorado and Texas, as well as far northern Mexico, where it grows in mostly dry habitat types in a number of regions.


It is a perennial herb growing upright to about 80 centimetres (31 in) in maximum height. The leaves are oppositely arranged on the spreading stem branches. Each fleshy leaf has an oval or rounded blade up to 12 centimetres (4.7 in) long and is hairless or sparsely hairy. The flowers occur in leaf axils on the upper branches. Usually six flowers bloom in a bell-shaped involucre of five partly fused bracts. Each five-lobed, funnel-shaped flower is 4 to 6 centimetres (1.6 to 2.4 in) wide and magenta in color.


Investigations of archaeological material from southern Germany indicate that the prehistoric population of that region may well have relied significantly upon wild water caltrops to supplement their normal diet and, in times of cultivated cereal crop failure, water caltrops may even have been the main dietary component. Today, water caltrop is so rare in Germany that it is listed as an endangered species.
Water caltrop has been an important food for worship as prayer offerings since the Chinese Zhou Dynasty. The Rites of Zhou (second century BC) mentioned that a worshipper "should use a bamboo basket containing dried water caltrops, the seeds of Euryale ferox and caltrops" (加籩之實，菱芡栗脯). The Chinese Herbal Medicine Summary (本草備要 published in 1694, written by Wang Ang 汪昂) indicates that water caltrop can help fever and drunkenness.
In India and Pakistan, it is known as singhara or paniphal (eastern India) and is widely cultivated in freshwater lakes. The fruits are eaten raw or boiled. When the fruit has been dried, it is ground to a flour called singhare ka atta, used in many religious rituals, and can be consumed as a phalahar (fruit diet) on the Hindu fasting days, the navratas.
It was possible to buy water caltrops in markets all over Europe until 1880. In northern Italy, the nuts were offered roasted, much as sweet chestnuts (Castanea sativa) are still sold today. In many parts of Europe, water caltrops were known and used for human food until the beginning of the 20th century. Today, however, it is a rare plant in Europe. Several reasons for its near extinction exist, such as climate fluctuations, changes in the nutrient content of water bodies, and the drainage of many wetlands, ponds, and oxbow lakes.
T. natans was, however, introduced to the US State of Massachusetts around 1874, as a planting in the Harvard University Botanic Garden. Staff gardener Louis Guerineau took it upon himself to throw seeds into Fresh Pond and other Cambridge waterways. This came to the attention of Medford-based botanist George E. Davenport, who decided to bring seeds and live plants to his friend Minor Pratt, in Concord. He and Pratt seeded a pond near the Sudbury River, and he suspected Pratt of conducting additional distributions. As early as 1879, concern was voiced by botanist Charles Sprague Sargent, director of Boston's Arnold Arboretum, that this non-native species threatened to become a nuisance, based on dense growths reported in Cambridge. Davenport confessed in an entry in the Bulletin of the Torrey Botanical Club, Vol. 6, page 352: "I have several times had plants of Trapa natans that were collected in the vicinity of Boston, during the present year, brought to me for identification, and I have entertained no doubt as to the manner of its introduction into waters outside Cambridge Botanic Garden. But that so fine a plant as this, with its handsome leafy rosettes and edible nuts, which would, if common, be as attractive to boys as hickory nuts now are, can ever become a 'nuisance' I can scarcely believe."
Water caltrop has been declared an invasive species from Vermont to Virginia, and is classified as a noxious weed in Florida, North Carolina, and Washington. As of 2020, both T. natans and T. bicornis have been reported growing wild in the waterways of the United States.
In Australia and its state of New South Wales water caltrop has been declared a noxious weed.


The fruits are edible raw or cooked, and the seeds can be eaten as well.


The water caltrop is any of three extant species of the genus Trapa: Trapa natans, Trapa bicornis and the endangered Trapa rossica. It is also known as buffalo nut, bat nut, devil pod, ling nut, lin kok, ling jow,  ling kio nut, mustache nut or singhara.
The species are floating annual aquatic plants, growing in slow-moving freshwater up to 5 metres (16 feet) deep, native to warm temperate parts of Eurasia and Africa. They bear ornately shaped fruits, which in the case of T. bicornis resemble the head of a bull or the silhouette of a flying bat. Each fruit contains a single very large, starchy seed. T. natans and T. bicornis have been cultivated in China and the Indian subcontinent for the edible seeds for at least 3,000 years.


The water caltrop's submerged stem reaches 3.7 to 4.6 metres (12 to 15 feet) in length, anchored into the mud by very fine roots. It has two types of leaves: finely divided, feather-like submerged leaves borne along the length of the stem, and undivided floating leaves borne in a rosette at the water's surface. The floating leaves have saw-tooth edges and are ovoid or triangular in shape, 2–3 centimetres (3⁄4–1+1⁄4 inches) long, on inflated petioles 5–9 cm (2–3+1⁄2 in) long, which provide added buoyancy for the leafy portion. Four-petalled white flowers form in early summer and are insect-pollinated. The fruit is a nut with four 1 cm (1⁄2 in) barbed spines. Seeds can remain viable up to 12 years, although most germinate within the first two years.
The plant spreads by the rosettes and fruits detaching from the stem and floating to another area on currents or by fruits clinging to objects, and animals.
The unrelated Eleocharis dulcis is also called a water chestnut. Eleocharis is also an aquatic plant raised for food since ancient times in China. E. dulcis is a sedge, whose round, crisp-fleshed corms are common in Chinese food.


Sitka spruce provides critical habitat for a large variety of mammals, birds, reptiles, and amphibians. Its thick, sharp needles are poor browse for ungulates, and only the new spring growth is eaten. However, in Alaska and British Columbia the needles of picea sitchensis comprise up to 90% of the winter diet of blue grouse.
It provides cover and hiding places for a large variety of mammals, and good nesting and roosting habitat for birds. Sitka deer require old-growth Sitka spruce forests for winter habitat, as the extensive foliage holds a significant percentage of fallen snow in a given area, thus allowing for better understory browsing and easier migration for terrestrial animals. Cavity nesting birds favor Sitka spruce snags, and the tree is used by bald eagles and peregrine falcons as nesting habitat.


Picea sitchensis, the Sitka spruce, is a large, coniferous, evergreen tree growing to almost 100 meters (330 ft) tall, with a trunk diameter at breast height that can exceed 5 m (16 ft). It is by far the largest species of spruce and the fifth-largest conifer in the world (behind giant sequoia, coast redwood, kauri, and western red cedar), and the third-tallest conifer species (after coast redwood and coast Douglas fir). The Sitka spruce is one of the few species documented to exceed 90 m (300 ft) in height. Its name is derived from the community of Sitka in southeast Alaska, where it is prevalent. Its range hugs the western coast of Canada and the US, continuing south into northernmost California.


This species can be found in North America.The MONA or Hodges number for Historis odius is 4545.


This cactus species has several narrow stems that rise vertically, growing from a single short trunk just above the ground level. These stems are about 15 cm (6 in) thick and grow to a height of 5 m (16 ft), however it has been known to reach 7 to 8 m (23 to 26 ft).  These stems rarely branch but rather grow annually from the tip of the last growth. The mature plant can reach a width of 3.5 m (12 ft). Each stem has twelve to nineteen 10 mm (3⁄8 in) high ribs that bear dark brown to black spines that turn gray as it matures. It takes 150 years to reach maturity. The older plants produce 75 mm (3 in) funnel-shaped white flowers annually which are open at night and close by the morning and have a purple or pink tint to them. These usually grow during April, May, and June. The organ pipe cactus is usually pollinated by bats. The plant also produces fruit about the size of a tennis ball. Beneath the fruit's spiny exterior is red flesh that has been described as tasting better than watermelon. This fruit has traditionally been harvested by the Seris, who call the plant ool [oːɬ], and is used as a medicine.


This species is found mostly in Mexico, mainly in Sonora and southern Baja California and Northern Sinaloa. It is also known to the United States, but is much rarer, with the notable exception of Organ Pipe Cactus National Monument. The plant is predominantly found on rocky hillsides up to 900 m (3,000 ft) in elevation.  It is sensitive to frost, so the species is rare in low desert areas, which can be more susceptible to frost. The plant is slow growing, and prefers well-drained soil and full sun.  However, when in the seedling stage, it requires shade, and will grow beneath a "nurse tree". It will need this for several years until it grows an adequate root system, which is mostly in the upper 10 cm of soil.


The larvae are C–shaped and have a firm, wrinkled, hairy body, a small head, and tiny legs. The larvae overwinter wherever they have been feeding, which may be in compost, manure, leaf mould, or rotting wood. They grow very quickly and will have moulted twice before the end of autumn. They have a two-year life cycle. They pupate in June or July. Some adult beetles may emerge in autumn, but the main emergence is in spring, when the beetles mate. After mating, the female beetles lay their eggs in decaying organic matter and then die.


Rose chafers are capable of fast flight; they fly with their wing cases down. They feed on pollen, nectar, and flowers, especially roses. They can be found among roses on warm sunny days from May until June or July, and occasionally as late as September. Rose chafers are found in southern and central Europe and in the southern part of the United Kingdom, where they sometimes seem to be very localized. They can also be found in South East Asia, in the countryside and outlying islands of Hong Kong. They are a beneficial saprophagous species (detritivores).

The wingspan is 30–35 mm. Adults are on the wing year-round.


The larvae feed on Hypericum aethiopicum and Chamaecrista mimosoides.


Eurema brigitta, the small grass yellow or broad-bordered grass yellow, is a small butterfly of the family Pieridae, that is, the yellows and whites. It is found in India, other parts of Asia, Australia and Africa.


Grown as a garden plant it provides useful groundcover. Numerous cultivars have been selected, of which 'Catlin's Giant' has gained the Royal Horticultural Society's Award of Garden Merit.
Bugle is also known as "carpenter's herb" for its supposed ability to stem bleeding.
Bugle is a primary nectar source of the pearl-bordered fritillary and the small pearl-bordered fritillary.  It is a secondary nectar source of the brimstone, chequered skipper, common blue, cryptic wood white, dingy skipper, Duke of Burgundy, green-veined white, grizzled skipper, heath fritillary, holly blue, large blue, large skipper, large white, marsh fritillary, orange-tip, painted lady, small white, and wood white butterflies.
Ajuga reptans herb has been used in traditional Austrian medicine internally as a tea for the treatment of disorders related to the respiratory tract.


Ajuga reptans is commonly known as bugle, blue bugle, bugleherb, bugleweed, carpetweed, carpet bugleweed, and common bugle, and traditionally but less commonly as St. Lawrence plant. It is an herbaceous flowering plant, in the mint family, native to Europe. It is invasive in parts of North America.  Ajuga reptans is also a component of purple moor grass and rush pastures, a Biodiversity Action Plan habitat in the United Kingdom.
Ajuga reptans has dark green leaves with purple highlights. It is a spreading and dense ground cover plant. The leaves grow 5–8 cm (2.0–3.1 in) tall, but in the spring it sends up 10–15 cm (3.9–5.9 in) tall flower stalks bearing many purple flowers. The flowers are frequently visited by flies, such as Rhingia campestris.


Ajuga reptans is a sprawling perennial herb with erect flowering stems and grows to a height of about 10 to 35 cm (4 to 14 in). The stems are square, in cross-section, with hairs on two sides and the plant has runners that spread across the surface of the ground. The purplish-green, stalked leaves are in opposite pairs. The leaf blades are hairless and are elliptical or ovate with a rounded tip and shallowly rounded teeth on the margin. The inflorescence forms a dense raceme and is composed of whorls of blue flowers, each with dark veins on the lower lip. The calyx has five toothed lobes and the corolla forms a two-lipped flower about 14 to 17 mm (0.6 to 0.7 in) long with a short tube. The upper lip of each flower is short and flat with a smooth edge and the lower lip is three-lobed, the central lobe being the largest, flat with a notched tip. There are four stamens, two long and two short, which are longer than the corolla and are attached to the tube. The ovary is superior and the fruit is a schizocarp with four chambers.


Actaea rubra, the red baneberry or chinaberry, is a poisonous herbaceous flowering plant in the family Ranunculaceae, native to North America.


All parts of the plant are poisonous. However, accidental poisoning is not likely since the berries are extremely bitter.
The berries are the most toxic part of the plant. A healthy adult will experience poisoning from as few as six berries. Ingestion of the berries causes nausea, dizziness, increased pulse and severe gastrointestinal discomfort. The toxins can also have an immediate sedative effect on the cardiac muscle tissue possibly leading to cardiac arrest if introduced into the bloodstream. As few as two berries may be fatal to a child.
The fruits and foliage contain ranunculin, and are often reported to contain protoanemonin. The plant also contains berberine.
All parts of the plant contain an irritant oil that is most concentrated within the roots and berries.
The roots contain β-sitosterol glucoside.
There have been no reported cases of severe poisoning or deaths in North America, but children have been fatally poisoned by its European relative A. spicata. It is claimed that poisoning is unlikely from eating the fruits of this species also.
This plant closely resembles mountain sweetroot (Osmorhiza chilensis), and can be confused with it; however, red baneberry lacks the strong anise-like "spicy celery" odor of mountain sweetroot.
The following illustrates a non-fatal case of experimental self-intoxication produced by the ingestion of fruit from Actaea rubra. The onset of symptoms began within 30 minutes.
At first there was a most extraordinary pyrotechnic display of blue objects of all sizes and tints, circular with irregular edges; as one became interested in the spots a heavy weight was lowered on the top of the head and remained there, while sharp pains shot through the temples.
Then suddenly the mind became confused and there was a total disability to recollect anything distinctly or arrange ideas with any coherency. On an attempt to talk, wrong names were given to objects, and although at the same time the mind knew mistakes were made in speech, the words seemed to utter themselves independently.
For a few minutes there was great dizziness, the body seeming to swing off into space, while the blue spots changed to dancing sparks of fire. The lips and throat became parched and the latter somewhat constricted; swallowing was rather difficult; there was intense burning in the stomach with gaseous eructations, followed by sharp colicky pains in the abdomen and also pain across the back over the kidneys. The pulse rose to 125, was irregular, wiry, tense; the heart fluttered most unpleasantly.

These symptoms lasted about an hour and were followed by a feeling of great weariness, but in three hours from the time of taking the dose all seemed to be again normal".


They are found growing in shady areas with moist to wet soils, open forest or dry slopes. In Alaska it ranges from the Kenai Peninsula, through Kodiak Island, Bristol Bay, and up the Yukon River.


It is a perennial herb that grows 40 to 80 cm (16 to 31 in) tall.
The leaves are coarsely toothed with deeply lobed margins. Plants commonly have hairy veins on the undersides of the foliage. Each stem will have either three leaves that branch near the top, or will have three compound leaves and one upright flowering stalk from one point on the main central stem.
Plants produce one to a few ternately branched stems which bear clusters of flowers having 3 to 5 sepals that are petal-like and obovate in shape and remain after flowering. The petals are deciduous, falling away after flowering is done. They are clawed at the base and 2.5 to 4 mm (0.10 to 0.16 in) long and spatulate to obovate in shape. Flowers have numerous stamens and they are white in color.

After flowering green berries are produced. The fruits are ellipsoid shaped berries containing several seeds.
 In mid to late summer, the berries turn bright red, or white in forma neglecta. The berries also have a black dot on them.


Orthilia is a genus of flowering plants in the family Ericaceae. It has only one species, Orthilia secunda. Its common names are sidebells wintergreen, one-sided-wintergreen and serrated-wintergreen. It is also called one-sided pyrola, one-sided shinleaf, and one-sided wintergreen.  It was previously part of genus Pyrola, the wintergreens.
The plant has a circumboreal distribution, growing throughout much of the Northern Hemisphere.
The American wintergreen, Gaultheria procumbens, belongs to a different genus.


Daphne mezereum is very toxic because of the compounds mezerein and daphnin present especially in the berries and twigs. If poisoned, victims experience a choking sensation. Handling the fresh twigs can cause rashes and eczema in sensitive individuals. Despite this, it is commonly grown as an ornamental plant in gardens for its attractive flowers.  The native wild version became a protected species in the UK in 1975 under the Conservation of Wild Creatures and Wild Plants Act.


It is a deciduous shrub growing to 1.5 m tall. The leaves are soft, 3–8 cm long and 1–2 cm broad, arranged spirally on the stems. The flowers are produced in early spring on the bare stems before the leaves appear. They have a four-lobed pink or light purple (rarely white) perianth 10–15 mm diameter, and are strongly scented. The fruit is a bright red berry 7–12 mm diameter; it is very poisonous for humans, though fruit-eating birds like thrushes are immune and eat them, dispersing the seeds in their droppings.


Daphne mezereum, commonly known as mezereum, mezereon,  February daphne, spurge laurel or spurge olive, is a species of Daphne in the flowering plant family Thymelaeaceae, native to most of Europe and Western Asia, north to northern Scandinavia and Russia. In southern Europe it is confined to medium to higher elevations and in the subalpine vegetation zone, but descends to near sea level in northern Europe. It is generally confined to soils derived from limestone.


The soft tree fern can be used as a food source, with the pith of the plant being eaten either cooked or raw. It is a good source of starch.
The 1889 book 'The Useful Native Plants of Australia records that "The pulp of the top of the trunk is full of starch, and is eaten by the aboriginals [sic.] both raw and roasted. The native blacks [sic.] of the colony used to split open about a foot and a-half of the top of the trunk, and take out the heart,
in substance resembling a Swedish turnip, and of the thickness of a man's arm. This they either roasted in the ashes, or ate as bread; but it is too bitter and astringent to suit an English palate. (Gunn)"


Dicksonia antarctica, the soft tree fern or man fern, is a species of evergreen tree fern native to eastern Australia, ranging from south-east Queensland, coastal New South Wales and Victoria to Tasmania.


These ferns can grow to 15 m (49 ft) in height, but more typically grow to about 4.5–5 m (15–16 ft), and consist of an erect rhizome forming a trunk. They are very hairy at the base of the stipe (adjoining the trunk) and on the crown. The large, dark green, roughly-textured fronds spread in a canopy of 2–6 m (6 ft 7 in–19 ft 8 in) in diameter. The shapes of the stems vary as some grow curved and there are multi-headed ones. The fronds are borne in flushes, with fertile and sterile fronds often in alternating layers.
The "trunk" of this fern is merely the decaying remains of earlier growth of the plant and forms a medium through which the roots grow. The trunk is usually solitary, without runners, but may produce offsets. They can be cut down and, if they are kept moist, the top portions can be replanted and will form new roots. The stump, however, will not regenerate since it is dead organic matter. In nature, the fibrous trunks are hosts for a range of epiphytic plants including other ferns and mosses.
The fern grows at 3.5 to 5 cm per year and produces spores at the age of about 20 years.


Arctous alpina has a circumpolar distribution. It is found at high latitudes, from Scotland east across Scandinavia, Russia, Alaska, Northern Canada and Greenland. Its southern limits in Europe are the Pyrenees and the Alps, in Asia, the Altay Mountains and Mongolia, and in North America, British Columbia in the west, and Maine and New Hampshire in the east. Its natural habitat is moorland, dry forests with birch and pine and hummocks covered in moss at the edges of bogs.


Arctous alpina forms a symbiotic relationship life with fungi which supply it with nutrients such as phosphorus. The berries are appreciated by birds.


Arctous alpina is a procumbent shrub usually less than 6 inches (15 cm) high with a woody stem and straggling branches. The leaves are alternate and wither in the autumn but remain on the plant for another year. The leaves are stalked and are oval with serrated margins and a network of veins. They often turn red to scarlet in autumn. The flowers are in groups of two to five, white or pink and urn-shaped and about 3 to 5 mm (0 to 0 in) long. They have five sepals, five fused petals with five small projecting lobes, ten stamens and a single carpel. The fruits are spherical, 9 to 12 mm (0 to 0 in) long, initially green, then red and finally glossy black and succulent when ripe. This plant flowers in June.


The species flowering stalk is located 200 millimetres (7.9 in) above the leaves with the sticky purple colored awns. Flowers appear from December to June. It grows 0.3 metres (1 ft 0 in) high and has some hairs which have 10-15 nerves on either side. The plant is whitish on the lower surface and is very narrow near midrib.
It is self-pollinated plant whose seeds attract various animals and birds. The sticky seeds are easily distributed by animals and humans, easily adhering to fur and clothing.


Oplismenus hirtellus (commonly known as basket grass) is a flowering perennial plant from the family Poaceae that can be found on every continent in the world except Antarctica, growing mostly in coastal tropic and subtropic regions as well as tropical and subtropical islands such as Hawaii, New Zealand, Australia and Madagascar.


Traditionally, the plant has been a part of certain indigenous cultures of British Columbia, as a source of food, medicine, and for other uses. The rhizomes are edible after cooking and removing the skin, while peeled stems and leaf bases can be eaten raw or cooked. The young flower spikes, young shoots, and sprouts at the end of the rootstocks are edible as well. The pollen from the mature cones can be used as a flavoring. The starchy rootstalks are ground into meal by Native Americans.
It is not advisable to eat specimens deriving from polluted water as it absorbs pollutants and in fact is used as a bioremediator. Specimens with a very bitter or spicy taste should not be eaten.


Typha latifolia (broadleaf cattail, bulrush, common bulrush, common cattail, cat-o'-nine-tails, great reedmace, cooper's reed, cumbungi) is a perennial herbaceous plant in the genus Typha. It is found as a native plant species in North and South America, Eurasia, and Africa.


Typha latifolia grows 1.5 to 3 metres (5 to 10 feet) high and it has leaves 2–4 centimetres (3⁄4–1+1⁄2 inches) broad. It will generally grow from 0.75 to 1 m (2 to 3 ft) of water depth.


While caribou do not have specialized food habits, they can eat most plants - preferring fungi, green leaves of deciduous shrubs, and new spring growth of sedges. They often eat Kalmia polifolia in the spring and summer; the plant comprises 11% of their dietary dry-matter protein.


Kalmia polifolia flowers in April and is pollinated by bees. Bees, however, after pollinating this plant, produce a poison honey. Its seeds ripen in September. These seeds are five-parted, round, and woody.
Kalmia polifolia can grow to be two feet tall. Its leaves are arranged oppositely upon its branch and grow to be an inch to an inch and a half in length and tend to be waxy with an entire and revolute margin. Below each leaf base there are ridges, where it appears as though a part of the leaf is curled around the circumference of the stem. This is especially noticeable lower on the plant.
The base of the petiole is pressed against the stem as its flowers cluster in a single terminal bunch, which appears to be pink or purple in colour; the near cup-shaped flower spans about three-eighths of an inch in diameter.

Frangula caroliniana is usually around 12 to 15 feet (3.6-4.5 meters) high, but capable of reaching 40 feet (12 meters) in a shaded location. The most striking characteristic of this plant are its shiny, dark green leaves. The flowers are very small and inconspicuous, pale yellow-green, bell-shaped, appearing in leaf axils in late spring after the leaves. The fruit is a small (1/3 inch or 8.3 mm) round drupe; at first red, but later turning black with juicy flesh. It ripens in late summer.
Despite its common name, the Carolina buckthorn is completely thornless.


Frangula caroliniana, commonly called the  Carolina buckthorn, is a deciduous upright shrub or small tree native to the southeastern, south-central, and mid-western parts of the United States, from Texas east to Florida and north as far as Maryland, Ohio, Missouri, and Oklahoma. There is also an isolated population in the State of Nuevo León in northeastern Mexico. It is found in a wide variety of habitats, including barrens, forests, and limestone bluffs.


Wildlife such as songbirds eat the fruits, which are reported to have medicinal uses.


In the U.K. the habitat is often pastures and flowery banks, and nearby areas where the preferred food plants for the larvae, Viola canina and Viola riviniana, grow.
The dark green fritillary uses violets within bracken mosaics frequently consisting of one-third bracken and two-thirds grass, often on the edges of suitable high brown fritillary habitat. Their distribution can be found on the NBN website.


The dark green fritillary (Speyeria aglaja) is a species of butterfly in the family Nymphalidae. The insect has a wide range in the Palearctic realm - Europe, Morocco, Iran, Siberia, Central Asia, China, Korea, and Japan.


Commonly eaten by Maori in New Zealand, for whom it is known as Tutae Koau, sea celery was also an important vegetable for early explorers and colonists in Australia and New Zealand. Captain Cook ate sea celery at Botany Bay and gathered it in bulk along with Lepidium oleraceum at Poverty Bay in New Zealand in October 1769 to protect his crew from scurvy. It was commonly eaten by colonists as a survival food in the early days of the Sydney colony.
Both leaf and stem are eaten. Dried leaves are used in native Australian spice mixes. It tastes much the same as celery and is used to flavour soups. Variety filiforme is considered to be more palatable.
It was cultivated by colonists around Albany, Western Australia, as a vegetable. It is commercially cultivated to a limited extent.


Apium prostratum, commonly known as sea celery, is a variable herb native to coastal Australia and New Zealand. The leaves are variable, with toothed leaflets, and a celery like aroma. The tiny white flowers occur in clusters.
There are two varieties:
Apium prostratum var. filiforme – headland sea celery, squat with broad leaves (2-3 times longer than wide)and grows on coastal dunes and headlands.
Apium prostratum var. prostratum – mangrove sea celery, upright with fine leaves (6-15 times longer than wide) and grows in swamps.
The subspecies Apium prostratum subsp. howense is endemic to Lord Howe Island.


Fraxinus americana, the white ash or American ash, is a species of ash tree native to eastern and central North America.
The species is native to mesophytic hardwood forests from Nova Scotia west to Minnesota, south to northern Florida, and southwest to eastern Texas. Isolated populations have also been found in western Texas, Wyoming, and Colorado, and the species is reportedly naturalized in Hawaii.
There are an estimated 8 billion ash trees in the United States – the majority being the white ash trees and the green ash trees.


It is grown in Hungary for essential oil and menthol production. It also contains a significant amount of pulegone.
The leaves have a distinct peppermint smell when pinched or crushed as the plant contains aromatic oils. The leaves can be picked at any time during plant growth, and may be dried. They are used in making mint jelly, mint tea, and mint leaf candy. First nations people use mint tea for bad breath or toothache, or to cure hiccups. The mint can also be used for fox or lynx bait.
Mint essential oil is known to be effective as insect repellent for insects such as Drosophila melanogaster.


Mentha canadensis is a species of mint native to North America (from the Northwest Territories to central Mexico) and the eastern part of Asia (from Siberia to Java). In North America, it is commonly known as Canada mint, American wild mint, and in Asia as Chinese mint, Sakhalin mint, Japanese mint, and East Asian wild mint. The flowers are bluish or have a slight violet tint. The plant is upright, growing to about 4–18 in (10–46 cm) tall. Leaves grow opposite from each other, and flower bunches appear in the upper leaf axils. The mint grows in wet areas but not directly in water, so it will be found near sloughs, and lake and river edges. Plants bloom from July to August in their native habitats.
The plants found in eastern Asia have been called Mentha sachalinensis, among other synonyms.


One of the most important essential oils used in medicine is Japanese mint oil. Mentha canadensis is rich in natural menthol compared to other mint species, and menthol is used extensively in a number of pharmaceutical preparations. Approximately 4000 tons of Japanese mint oil and 2000 tons of menthol were produced in the world in 1998. The major producing countries are Brazil, Paraguay, Taiwan, Japan, China, India, and Thailand.


Adenophyllum porophylloides is a species of flowering plant in the family Asteraceae known by the common names San Felipe dogweed and San Felipe dyssodia. It is native to the Sonoran and Mojave Deserts of the southwestern United States (Arizona, California, Nevada) and northwestern Mexico (Sonora, Baja California, Baja California Sur).
Adenophyllum porophylloides is an aromatic desert subshrub with several branching stems reaching a maximum height near 60 centimeters. The sparse, clawlike leaves are divided into sharply pointed linear lobes that bear prominent resin glands. The foliage has an unpleasant scent. The inflorescence is borne on a peduncle several centimeters long. The flower head is cylindrical and lined with phyllaries with large resin glands on them. The tip of the head blooms with bright yellow to reddish orange disc florets. There are sometimes short, stubby yellow to reddish ray florets along the rim. The fruit is an achene about 5 millimeters long with a bristly, scaly pappus.


Brachystola magna, one of the grasshoppers known as plains lubber or western lubber, is a large grasshopper native to southern and central USA and Northern Mexico.
It is reddish brown with black dots on its outer wings, however there is some variation in colouration, with more northern races being greener, and southern ones more buff. The Brachystola magna has extremely small wings and is unable to fly. The antennae are bluish-brown and the legs are reddish near the body with purple tarsi. It has a ridge along the upper and middle region of the abdomen. It is distinguished from Brachystola virescens by its longer antennae and colour.
In Wyoming it is found on gravelly ground in the southwest of the state. It does not cause significant damage to crops, and seems to prefer coarse broadleaved plants to crops. It overwinters in the egg, which hatch in the spring and reach adulthood in August.
Walter Sutton's description of reduction division was based on studying the spermatocytes of Brachystola magna. This work was critical in the development of the chromosome theory of inheritance.


Gaylussacia baccata closely resembles the native blueberry plants (Vaccinium species) with which it grows in the same habitats. However, it can be readily identified by the numerous resin dots on the undersides of the leaves which glitter when held up to the light.  Gaylussacia baccata is a shrub up to 150 cm (5 feet) tall, forming extensive colonies. Flowers are in dangling groups of 3–7, orange or red, bell-shaped. Berries are dark blue, almost black, rarely white.
Berries are sweet and tasty. People and animals eat them raw, jellied, or baked into pancakes, muffins, and many other items.


Galen, a Greek physician of the 2nd century A.D., knew of alder buckthorn, although he did not distinguish clearly in his writings between it and other closely related species. All of these plants though, were credited with the power to protect against witchcraft, demons, poisons, and headaches.
The bark (and to a lesser extent the fruit) has been used as a laxative, due to its 3–7% anthraquinone content. Bark for medicinal use is dried and stored for a year before use, as fresh bark is violently purgative; even dried bark can be dangerous if taken in excess.


Alder buckthorn is a non-spiny deciduous shrub, growing to 3–6 m (10–20 ft), occasionally to 7 m (23 ft) tall. It is usually multistemmed, but rarely forms a small tree with a trunk diameter of up to 20 cm (8 in). The bark is dark blackish-brown, with bright lemon-yellow inner bark exposed if cut. The shoots are dark brown, the winter buds without bud scales, protected only by the densely hairy outer leaves.
The leaves are arranged alternately on 8–15-millimetre (5⁄16–19⁄32-inch) petioles. They are ovate, 3–7 cm (1+1⁄4–2+3⁄4 in) long by 2.5–4 cm (1–1+5⁄8 in) wide (rarely to 11 cm or 4+1⁄4 in by 6 cm or 2+1⁄4 in). They have 6–10 pairs of prominently grooved and slightly downy veins and an entire margin.
The flowers are small, 3–5 mm (1⁄8–3⁄16 inch) in diameter, star-shaped with five greenish-white acute triangular petals, hermaphroditic, and insect-pollinated, flowering in May to June in clusters of two to ten in the leaf axils.
The fruit is a small black berry 6–10 mm (1⁄4–13⁄32 inch) in diameter, ripening from green through red in late summer to dark purple or black in early autumn, containing two or three pale brown 5-millimetre (3⁄16-inch) seeds. The seeds are primarily dispersed by frugivorous birds, which readily eat the fruit.


Frangula alnus, commonly known as alder buckthorn, glossy buckthorn, or breaking buckthorn, is a tall deciduous shrub in the family Rhamnaceae. Unlike other "buckthorns", alder buckthorn does not have thorns. It is native to Europe, northernmost Africa, and western Asia, from Ireland and Great Britain north to the 68th parallel in Scandinavia, east to central Siberia and Xinjiang in western China, and south to northern Morocco, Turkey, and the Alborz in Iran and Caucasus Mountains; in the northwest of its range (Ireland, Scotland), it is rare and scattered. It is also introduced and naturalised in eastern North America.


Alder buckthorn grows in wet soils in open woods, scrub, hedgerows and bogs, thriving well in sunlight and moderate shade, but less vigorously in dense shade; it prefers acidic soils though will also grow on neutral soils.
Frangula alnus is one of just two food plants (the other being Rhamnus cathartica) used by the common brimstone butterfly (Gonepteryx rhamni). The flowers are valuable for bees, and the fruit an important food source for birds, particularly thrushes.


Males and females: Upperside very similar to the above, paler; in the female often the ground colour ochraceous white, closely irrorated with brown striae; ocelli as in the wet-season form, but those on the hindwing often non-pupilled. Underside also paler than in the wet-season form, the subbasal, discal and subterminal bands on the whole more prominent; ocelli on the hindwing reduced to mere specks.
Wingspan of 38–46 mm.

Ypthima baldus, the common five-ring, is a species of Satyrinae butterfly found in Asia.


Native Americans used the sprouts to create baskets, fish traps, and baby carriers. The nuts were eaten and commonly used as a trade good among indigenous groups- both the Lewis and Clark expedition and prolific early naturalist David Douglas bartered for beaked hazelnuts with local peoples they encountered. It was used medicinally as emetic, for deworming, as an astringent, and for teething.
It is considered an excellent nut, with the same uses as any hazelnut. While the beaked hazelnut does not produce as many nuts as commercial European species such as the common hazel or filbert, it is more resistant to common diseases, and has been used in breeding programs to create high-yield, disease resistant hybrids.
It is used in restoration plantings to increase biodiversity, improve food sources for wildlife, and to reduce rates of laminated root rot in nearby Douglas-fir and Sitka spruce.


The beaked hazelnut can reach 4–8 metres (13–26 feet) tall with stems 10–25 centimetres (4–9+3⁄4 inches) thick with smooth gray bark, but it can also remain relatively small in the shade of other plants. It typically grows with several trunks.
The leaves are green, rounded oval with a pointed tip, coarsely double-toothed, 5–11 cm (2–4+1⁄4 in) long and 3–8 cm (1+1⁄4–3+1⁄4 in) broad, with soft and hairy undersides.
The male flowers are catkins that form in autumn, pollinating the single female flowers the following spring to allow the fruits to mature through the summer.
The beaked hazelnut is named for its fruit, which is a nut enclosed in a husk with a tubular extension 2–4 cm (3⁄4–1+1⁄2 in) long that resembles a beak. Tiny filaments protrude from the husk and may stick into, and irritate, skin that contacts them. The spherical nuts are small and surrounded by a hard shell. The beaked hazel is the hardiest of all hazel species, surviving temperatures of −50 °C (−58 °F) at its northern limits.
It has a shallow and dense root system which is typically only 15 cm (6 in) deep, with a single taproot which may extend 0.6 m (2 ft) below the surface.


Corylus cornuta, the beaked hazelnut (or just beaked hazel), is a deciduous shrubby hazel with two subspecies found throughout most of North America.


The melliferous flowers are solitary or in pairs, and grow in the leaf axils. Greenish or yellowish in color, they have 5 lanceolate sepals, but no petals. Flowering takes place from late summer to late winter.
The inedible fruit is not hardy and transitions from green to indigo, purple and, lastly, black as it ripens. The glabrous fruits contain a multitude of tiny seeds in a dark blue pulp, which are dispersed by birds.


Its range stretches from Florida and the Lower Rio Grande Valley of Texas in the United States south through Mexico, Central America, and the Caribbean to South America. In 1909, it was introduced in Polynesia and Australia.
It is extremely prolific (up to 1000 seeds per square meter), smothering any vegetation it grows on, including trees. In New Caledonia, it is prohibited to introduce the species into the wild.


It is a creeping or climbing perennial liana up to 6 meters long. It has suberous stems in its lower part, glabrous to puberulent.
The leaves are simple, alternate, entire to three-lobed, with both sides glabrous, shiny green. They are 4 to 12 centimeters long when elliptical and up to 5 cm long and 7 cm wide when deeply lobed, sharp lobes, base rounded to truncated, glabrous to puberulent; petioles 0.5–4 cm long, with a pair of conspicuous and stipitate glands in upper half; linear stipules.
The plant is known for the fact that the leaves on one and the same plant vary greatly in shape and size. Another well-known phenomenon is that the lower part of the trunk becomes corky with aging.


Rubus hispidus, with the common names swamp dewberry, bristly dewberry, bristly groundberry, groundberry, hispid swamp blackberry or running swamp blackberry, is North American species of dewberry in the rose family.
The plant grows in moist or sometimes dry soils, ditches, swales or open woods in central and eastern North America, from Ontario and Minnesota east to Newfoundland, and south to South Carolina and Mississippi.


The plant is eaten by birds and many mammals.
A dull blue dye can be created from its berries. The fruit also can be used as an astringent.
The berries are rather bitter for culinary use, and so this plant is generally not cultivated.


Rubus hispidus is a small, herb-like shrub up to 20 cm (8 inches) tall.  The twigs are red and have bristles. Flowers are generally in small clumps, each with five white rounded petals. The fruit are dark purple, almost black.


Juniperus deppeana (alligator juniper or checkerbark juniper; Native American names include táscate and tláscal) is a small to medium-sized tree reaching 10–15 metres (33–49 feet), rarely 25 m, in height. It is native to central and northern Mexico (from Oaxaca northward) and the southwestern United States (Arizona, New Mexico, western Texas). It grows at moderate altitudes of 750–2,700 m (2,460–8,860 ft)  on dry soils.
The bark is usually very distinctive, unlike other junipers, hard, dark gray-brown, cracked into small square plates superficially resembling alligator skin; it is however sometimes like other junipers, with stringy vertical fissuring. The shoots are 1–1.5 millimetres in diameter; the leaves are arranged in opposite decussate pairs or whorls of three; the adult leaves are scale-like, 1-2.5 mm long (to 5 mm on lead shoots) and 1–1.5 mm broad. The juvenile leaves (on young seedlings only) are needle-like, 5–10 mm long. The cones are berry-like, 7–15 mm in diameter, green maturing orange-brown with a whitish waxy bloom, and contain 2–6 seeds; they are mature in about 18 months, and are eaten by birds and mammals. The male cones are 4–6 mm long, and shed their pollen in spring. It is largely dioecious, producing cones of only one sex on each tree, but occasional trees are monoecious.
There are five varieties, not accepted as distinct by all authorities:
Juniperus deppeana var. deppeana. Throughout the range of the species. Foliage dull gray-green with a transparent or yellowish resin spot on each leaf; cones 7–12 mm diameter.
Juniperus deppeana var. pachyphlaea (syn. J. pachyphlaea). Arizona, New Mexico, northernmost Mexico. Foliage strongly glaucous with a white resin spot on each leaf; cones 7–12 mm diameter.
Juniperus deppeana var. robusta (syn. J. deppeana var. patoniana). Northwestern Mexico. Cones larger, 10–15 mm diameter.
Juniperus deppeana var. sperryi. Western Texas, very rare. Bark furrowed, not square-cracked, branchlets pendulous; possibly a hybrid with Juniperus flaccida.
Juniperus deppeana var. zacatecensis. Zacatecas. Cones large, 10–15 mm diameter.


Trifolium arvense is a small erect herbaceous annual or biennial plant, growing to 10–40 cm tall. Like all clovers, its leaves are trifoliate, divided into three slender, sessile leaflets 1–2 cm long and 3–5 mm broad, sometimes edged with small hairs and finely serrated. The leaves have a pair of stipules at the base, often tipped in red. The flowers are grouped in a dense inflorescence 2–3 cm long and 1-1.5 cm broad; each flower is 4–5 mm long, rosy white in colour, and especially characterised by the many silky white hairs which tip the five sepals, which are much larger than the petals. These hairs, along with the more or less oblong form of the inflorescence, are the inspiration for the common name. Pollination is carried out by bees, or via autogamy, since the plant is hermaphroditic, and the flowering season is from mid-spring to late summer. The fruit is a small pod containing a single seed.


Trifolium arvense is native to Europe and has been introduced to North America where it now appears throughout the eastern United States, southern Canada, and the western part of the U.S. along the Pacific Coast. The plant has also been recorded in some parts of Hawaii.


Umbrella magnolias have large shiny leaves 30–50 cm long, spreading from stout stems. In a natural setting the umbrella magnolia can grow 15 m tall. The flowers are large, appear in the spring, malodorous, 15–25 cm diameter, with six to nine creamy-white tepals and a large red style, which later develops into a red fruit (an aril) 10 cm long, containing several red seeds. These trees are attractive and easy to grow. The leaves turn yellow in the autumn. The leaves are clustered at the tip of the stem with very short internodes. The tree has reddish cone-shaped fruit, is shade tolerant, has shallow spreading roots, and is pollinated by beetles.


Magnolia tripetala, commonly called umbrella magnolia or simply umbrella-tree,  is a deciduous tree native to the eastern United States in the Appalachian Mountains, the Ozarks, and the Ouachita Mountains.  The name "umbrella tree" derives from the fact that the large leaves are clustered at the tips of the branches forming an umbrella-shaped structure.


The largest known Magnolia tripetala is 15.2 m in height with a trunk diameter of 87 cm in Bucks County, Pennsylvania.


Leptotes pirithous is a small butterfly with a wingspan of 21–29 mm in males and 24–30 mm in females. The uppersides of the wings are purple bluish in males, bluish brown in female. The undersides are dark beige striped with white lines. The hindwings show marginal orange and black spots and two small tails. For the design of the undersides of the wings they can be confused with Lampides boeticus and Cacyreus marshalli. These butterflies fly from February to November depending on the location. They are regular migrants.
The larvae feed on the flowers and fruits of Fabaceae, Rosaceae and Plumbaginaceae species, including  Plumbago capensis, Indigofera, Rynchosia, Vigna, Burkea, Mundulea, Melilotus, Crataegus, Quercus suber, Medicago sativa, Trifolium alexandrinum, Arachis hypogaea, Lythrum, Calluna, Genista, Dorycnium, Lythrum salicaria, Calluna vulgaris, Onobrychis viciifolia, Ulex and Melilotus alba. A life cycle takes about four to eight weeks, depending on the temperature.


This species can be found in southern Europe (Spain, France and Italy), along the Mediterranean coast, in Asia Minor up to the Himalayas, and in most of Africa and Madagascar.


This species prefers varied wasteland, cultivated areas and gardens.


Hesperis matronalis has been a cultivated species for a long time, and grows best in full sun to partial shade where soils are moist with good drainage. It is undemanding and self-seeds quickly, forming dense stands. Extensive monotypic stands of dame's rocket are visible from great distances; these dense collections of plants have the potential to crowd out native species when growing outside of cultivated areas.
The successful spread of dame's rocket in North America is attributed to its prolific seed production and because the seeds are often included in prepackaged "wildflower seed" mixes sold for "naturalizing". The plants typically produce a low-lying rosette of foliage the first year; in subsequent years, blooming and seed production occurs in tandem throughout the blooming season. This species is commonly found in roadside ditches, dumps and in open woodland settings, where it is noticed when in bloom. Although it makes an attractive, hardy garden plant, it has been found to be ecologically invasive in North America.
Hesperis matronalis is propagated by seeds, but desirable individuals, including the double-flowering forms, are propagated from cuttings or division of the clumps.
Young leaves are high in vitamin C and can be eaten in salads and have a slightly bitter taste. Seeds can be sprouted and also eaten in salads.


Hesperis matronalis grows 100 cm or taller, with multiple upright, hairy stems. Typically, the first year of growth produces a mound of foliage, and flowering occurs the second year; the plants are normally biennials, but a number of races can be short-lived perennials. The plants have showy blooms in early to mid spring. The leaves are alternately arranged on upright stems and lanceolate-shaped; they typically have very short or lack petioles and have toothed margins, but sometimes are entire and are widest at the base. The foliage has short hairs on the top and bottom surfaces that give the leaves a somewhat rough feel. The larger leaves are around 12 cm long and over 4 cm wide. In early spring, a thick mound of low-growing foliage is produced; during flowering the lower parts of the stems are generally unbranched and denuded of foliage and the top of the blooming plant might have a few branches that end in inflorescences.
The plentiful, fragrant flowers are produced in large, showy, terminal racemes that can be 30+ cm tall and elongate as the flowers of the inflorescence bloom. When stems have both flowers and fruits, the weight sometimes causes the stems to bend. Each flower is large (2 cm across), with four petals. Flower coloration varies, with different shades of lavender and purple most common, but white, pink, and even some flowers with mixed colors exist in cultivated forms. A few different double-flowered varieties also exist.  The four petals are clawed and hairless. The flowers have six stamens in two groups, the four closest to the ovary are longer than the two oppositely positioned. Stigmas are two-lobed. The four sepals are erect and form a mock tube around the claws of the petals and are also colored similarly to the petals.
Some plants may bloom until August, but warm weather greatly shortens the duration on each flower's blooming. Seeds are produced in thin fruits 5–14 cm long pods, containing two rows of seeds separated by a dimple. The fruit are terete and open by way of glabrous valves, constricted between the seeds like a pea pod. Seeds are oblong, 3–4 mm long and 1–1.5 mm wide.
In North America, Hesperis matronalis is often confused with native Phlox species that also have similar large showy flower clusters.  They can be distinguished from each other by foliage and flower differences: dame's rocket has alternately arranged leaves and four petals per flower, while phloxes have opposite leaves and five petals.


A garden escape, H. matronalis is found in many areas of Ireland, including Belfast.
Dame's rocket was brought to North America in the 17th century and has since become naturalized there, now growing throughout most of the US and Canada. The US Department of Agriculture website has a map showing states and provinces in which the plant has been found.
In Europe, it is host to the caterpillars of several butterfly species, including the orange tip (Anthocharis cardamines), large white (Pieris brassicae), small white (Pieris rapae), and moths, such as Plutella porrectella.


Like other insects that undergo complete metamorphosis, the western honey bee has four distinct life stages: egg, larva, pupa and adult. The complex social structure of western honey bee hives means that all of these life stages occur simultaneously throughout much of the year. The queen deposits a single egg into each cell of a honeycomb prepared by worker bees. The egg hatches into a legless, eyeless larva fed by "nurse" bees (worker bees who maintain the interior of the colony). After about a week, the larva is sealed in its cell by the nurse bees and begins its pupal stage. After another week, it emerges as an adult bee. It is common for defined regions of the comb to be filled with young bees (also called "brood"), while others are filled with pollen and honey stores.
Worker bees secrete the wax used to build the hive, clean, maintain and guard it, raise the young and forage for nectar and pollen; the nature of the worker's role varies with age. For the first 10 days of their lives, worker bees clean the hive and feed the larvae. After this, they begin building comb cells. On days 16 through 20, workers receive nectar and pollen from older workers and store it. After the 20th day, a worker leaves the hive and spends the remainder of its life as a forager. Although worker bees are usually infertile females, when some subspecies are stressed they may lay fertile eggs. Since workers are not fully sexually developed, they do not mate with drones and thus can only produce haploid (male) offspring.
Queens and workers have a modified ovipositor called a stinger, with which they defend the hive. Unlike bees of any other genus and the queens of their own species, the stinger of worker western honey bees is barbed. Contrary to popular belief, a bee does not always die soon after stinging; this misconception is based on the fact that a bee will usually die after stinging a human or other mammal. The stinger and its venom sac, with musculature and a ganglion allowing them to continue delivering venom after they are detached, are designed to pull free of the body when they lodge. This apparatus (including barbs on the stinger) is thought to have evolved in response to predation by vertebrates, since the barbs do not function (and the stinger apparatus does not detach) unless the stinger is embedded in elastic material. The barbs do not always "catch", so a bee may occasionally pull its stinger free and fly off unharmed (or sting again).
Although the average lifespan of a queen in most subspecies is three to five years, reports from the German honey bee subspecies (A. m. mellifera) previously used for beekeeping indicate that a queen can live up to eight years. Because a queen's store of sperm is depleted near the end of her life, she begins laying more unfertilized eggs; for this reason, beekeepers often replace queens every year or two.
The lifespan of workers varies considerably over the year in regions with long winters. Workers born in spring and summer work hard, and live only a few weeks, but those born in autumn remain inside for several months as the colony clusters. On average during the year, about 1% of a colony's worker bees die naturally per day. Except for the queen, all of a colony's workers are replaced about every four months.


Insect predators of western honey bees include the Asian giant hornet and other wasps, robber flies, dragonflies such as the green darner, some mantises, water striders and the European beewolf.
Arachnid predators of western honey bees include fishing spiders, lynx spiders, goldenrod spiders and St. Andrew's cross spiders.
Reptile and amphibian predators of western honey bees include the black girdled lizard, anoles, and other lizards, and various anuran amphibians including the American toad, the American bullfrog and the wood frog.
Specialist bird predators of western honey bees include the bee-eaters; other birds that may take western honey bees include grackles, hummingbirds, tyrant flycatchers and the summer tanager.  Most birds that eat bees do so opportunistically; however, summer tanagers will sit on a limb and catch dozens of bees from the hive entrance as they emerge.
Mammals that sometimes take western honey bees include bears, opossums, raccoons, skunks, the North American least shrew and the honey badger.


The western honey bee can be found on every continent except Antarctica. The species is believed to have originated in Africa or Asia, and it spread naturally through Africa, the Middle East and Europe. Humans are responsible for its considerable additional range, introducing European subspecies into North America (early 1600s), South America, Australia, New Zealand, and eastern Asia.
Western honey bees adapted to the local environments as they spread geographically. These adaptations include synchronizing colony cycles to the timing of local flower resources, forming a winter cluster in colder climates, migratory swarming in Africa, and enhanced foraging behavior in desert areas. All together, these variations resulted in 31 recognized subspecies.
Previously it was believed that the various subspecies were all cross-fertile, but in 2013 it was confirmed through research that the A. m. mellifera Queens do not hybridize with non-A. m. mellifera Drones.
The subspecies are divided into four major branches, based on work by Ruttner and confirmed by mitochondrial DNA analysis. African subspecies belong to branch A, northwestern European subspecies branch M, southwestern European subspecies branch C and Middle-Eastern subspecies branch O.


Unlike most other bee species, western honey bees have perennial colonies which persist year after year. Because of this high degree of sociality and permanence, western honey bee colonies can be considered superorganisms. This means that reproduction of the colony, rather than individual bees, is the biologically significant unit. Western honey bee colonies reproduce through a process called "swarming".
In most climates, western honey bees swarm in the spring and early summer, when there is an abundance of blooming flowers from which to collect nectar and pollen. In response to these favorable conditions, the hive creates one to two dozen new queens. Just as the pupal stages of these "daughter queens" are nearly complete, the old queen and approximately two-thirds of the adult workers leave the colony in a swarm, traveling some distance to find a new location suitable for building a hive (e.g., a hollow tree trunk). In the old colony, the daughter queens often start "piping", just prior to emerging as adults, and, when the daughter queens eventually emerge, they fight each other until only one remains; the survivor then becomes the new queen. If one of the sisters emerges before the others, she may kill her siblings while they are still pupae, before they have a chance to emerge as adults.
Once she has dispatched all of her rivals, the new queen, the only fertile female, lays all the eggs for the old colony, which her mother has left. Virgin females are able to lay eggs, which develop into males (a trait shared with wasps, bees, and ants because of haplodiploidy). However, she requires a mate to produce female offspring, which comprise 90% or more of bees in the colony at any given time. Thus, the new queen goes on one or more nuptial flights, each time mating with 1–17 drones. Once she has finished mating, usually within two weeks of emerging, she remains in the hive, playing the primary role of laying eggs.
Throughout the rest of the growing season, the colony produces many workers, who gather pollen and nectar as cold-season food; the average population of a healthy hive in midsummer may be as high as 40,000 to 80,000 bees.  Nectar from flowers is processed by worker bees, who evaporate it until the moisture content is low enough to discourage mold, transforming it into honey, which can then be capped over with wax and stored almost indefinitely. In the temperate climates to which western honey bees are adapted, the bees gather in their hive and wait out the cold season, during which the queen may stop laying. During this time, activity is slow, and the colony consumes its stores of honey used for metabolic heat production in the cold season. In mid- through late winter, the queen starts laying again.  This is probably triggered by day length. Depending on the subspecies, new queens (and swarms) may be produced every year, or less frequently, depending on local environmental conditions and a number of characteristics inside the hive.


Pleurocoronis pluriseta is a species of flowering plant in the family Asteraceae known by the common name bush arrowleaf. It is native to the southwestern United States and northern Mexico, where it grows in desert scrub and similar habitat. This is a clumpy or bushy subshrub reaching up to about half a meter in maximum height with many slender branches. The distinctive leaves are several centimeters in length and are mostly petiole; there is generally a toothed diamond- or arrowhead-shaped blade no more than one centimeter long at the very tip. The inflorescence is made up of one or two flower heads, sometimes more. Each flower head is somewhat cylindrical or bullet-shaped, measuring up to about a centimeter long. The head is discoid, containing only disc florets and no ray florets. It is lined with a series of many phyllaries coated thinly in glandular hairs and often streaked with purple-red coloration. The tips of the outer phyllaries curve outward. The fruit is a hairy, ribbed achene a few millimeters long with a pappus of bristles and scales on its tip.


Ruellia simplex, the Mexican petunia, Mexican bluebell or Britton's wild petunia, is a species of flowering plant in the family Acanthaceae. It is a native of Mexico, the Caribbean, and South America. It has become a widespread invasive plant in Florida, where it was likely introduced as an ornamental before 1933, as well as in the eastern Mediterranean, South Asia and other parts of the eastern hemisphere.


Ruellia simplex is an evergreen perennial growing 3 ft (0.91 m) tall, forming colonies of stalks with lance-shaped leaves that are 6 to 12 in (15 to 30 cm) and .5 to .75 in (1.3 to 1.9 cm) wide. Trumpet shaped flowers are metallic blue to purple, with five petals, and 3 in (7.6 cm) wide. There is a dwarf variety that is only 1 ft (0.30 m) tall.


P. strobus is found in the nearctic temperate broadleaf and mixed forests biome of eastern North America. It prefers well-drained or sandy soils and humid climates, but can also grow in boggy areas and rocky highlands. In mixed forests, this dominant tree towers over many others, including some of the large broadleaf hardwoods. It provides food and shelter for numerous forest birds, such as the red crossbill, and small mammals such as squirrels.
Fossilized white pine leaves and pollen have been discovered by Brian Axsmith, a paleobotanist at the University of South Alabama, in the Gulf Coastal Plain, where the tree no longer occurs.
Eastern white pine forests originally covered much of north-central and northeastern North America. Only 1% of the old-growth forests remain after the extensive logging operations from the 18th century to early 20th century.
Old-growth forests, or virgin stands, are protected in Great Smoky Mountains National Park. Other protected areas with known virgin forests, as confirmed by the Eastern Native Tree Society, include Algonquin Provincial Park, Quetico Provincial Park, Algoma Highlands in Ontario, and Sainte-Marguerite River Old Forest in Quebec, Canada; Estivant Pines, Huron Mountains, Porcupine Mountains State Park, and Sylvania Wilderness Area in the Upper Peninsula of Michigan, United States; Hartwick Pines State Park in the Lower Peninsula of Michigan; Menominee Indian Reservation in Wisconsin; Lost 40 Scientific and Natural Area (SNA) and Boundary Waters Canoe Area Wilderness in Minnesota; White Pines State Park, Illinois; Cook Forest State Park, Hearts Content Scenic Area, and Anders Run Natural Area in Pennsylvania; and the Linville Gorge Wilderness in North Carolina, United States.
Small groves or individual specimens of old-growth eastern white pines are found across the range of the species in the USA, including in Ordway Pines, Maine; Ice Glen, Massachusetts; and Adirondack Park, New York. Many sites with conspicuously large specimens represent advanced old-field ecological succession. The tall stands in Mohawk Trail State Forest and William Cullen Bryant Homestead in Massachusetts are examples.
As an introduced species, P. strobus is now naturalizing in the Outer Western Carpathians subdivision of the Carpathian Mountains in Czech Republic and southern Poland. It has spread from specimens planted as ornamental trees.


The eastern white pine has the distinction of being the tallest tree in eastern North America. In natural precolonial stands, it is reported to have grown as tall as 70 m (230 ft). No means exist for accurately documenting the height of trees from these times, but eastern white pine may have reached this height on rare occasions. Even greater heights have been reported in popular, but unverifiable, accounts such as Robert Pike's Tall Trees, Tough Men.
Total trunk volumes of the largest specimens are around 28 m³ (990 cu ft), with some past giants possibly reaching 37 to 40 m³ (1,300 to 1,400 cu ft). Photographic analysis of giants suggests volumes closer to 34 m³ (1,200 cu ft).


Catochrysops strabo, the forget-me-not, is a small butterfly found in Asia that belongs to the lycaenids or blues family. The species was first described by Johan Christian Fabricius in 1793. It is found in Sri Lanka, India, from Sikkim to Indochina and in Sundaland, Sulawesi and the Philippines.
The wingspan is 25–30 mm.
The larvae feed on Ougeinia dalbergioides, Schleichera trijuga and Desmodium species.


This species resides in Peninsular India south of the outer ranges of the Himalayas; Ceylon; Assam; Burma; Tenasserim; the Andamans; Nicobars; extending through the Malayan subregion down to Australia.


Brachymesia gravida, the four-spotted pennant, is a species of skimmer in the dragonfly family Libellulidae. It is found in North America.
The IUCN conservation status of Brachymesia gravida is "LC", least concern, with no immediate threat to the species' survival. The population is stable. The IUCN status was reviewed in 2017.


Penstemon procerus is a species of penstemon known by the common name littleflower penstemon. It is native to western North America from Alaska to California to Colorado, as far east in Canada as Manitoba, where it grows in mountain habitat such as meadows, often in alpine climates. This herbaceous perennial forms mats of herbage with some erect stems reaching about 40 centimeters in maximum height. There are several varieties which vary in morphology, some more decumbent than others, some of which are known commonly as pincushion penstemons for their matted forms. In general, the leaves are lance-shaped to oval, plentiful around the base of the plant with smaller ones arranged in opposite pairs along the stem. The inflorescence is made up of one or more clusters of tubular flowers with lipped, lobed mouths. Each flower is no more than one centimeter in length and is purple to blue in color, often with a white throat. The outside of the flower is generally hairless, while the inside may be lined with white or yellowish hairs.
The Latin specific epithet procerus means "tall".
In cultivation in the UK the cultivar 'Roy  Davidson' has won the Royal Horticultural Society's Award of Garden Merit. It copes with a range of situations, but requires a well-drained medium in full or partial sun.


Salvia coccinea is an annual species. It is cultivated in urban green areas as well as in private gardens around the world. It has a long flowering period, from the start of summer to the end of autumn. Cultivated varieties include orange-red, pink, salmon, red, white, and scarlet, as well as bi-colored varieties. The plant is hardy to USDA Hardiness Zones Zones 8–10.


Salvia coccinea, the blood sage, scarlet sage, Texas sage, or tropical sage, is a herbaceous perennial  in the family Lamiaceae that is widespread throughout the Southeastern United States, Mexico, Central America, the Caribbean, and northern South America (Colombia, Peru, and Brazil). At one time Brazil was considered to be where it originated, but its diploid chromosome count now points to Mexico as its place of origin.


Psorothamnus schottii is a species of flowering plant in the legume family known by the common name Schott's dalea. It is native to the Sonoran Deserts of northern Mexico and adjacent sections of Arizona and the Colorado Desert in California.


Psorothamnus schottii is a shrub approaching two meters in maximum height. Its highly branching stems are green to woolly gray-green and glandular. The gland-pitted linear leaves are up to 3 centimeters long and not divided into leaflets.
The inflorescence is an open raceme of up to 15 flowers. Each flower has a deep purple blue pealike corolla up to a centimeter long in a glandular tubular calyx of sepals with pointed lobes. The fruit is a legume pod coated in glands and containing one seed.


Heterotheca grandiflora is a species of flowering plant in the family Asteraceae known by the common name silk-grass goldenaster or telegraphweed. It is native to the southwestern United States (California, Nevada, Utah, Arizona) and northwestern Mexico (Baja California), but it can be found in other areas as an introduced species, such as Hawaii. It is often a roadside weed even where it is native.
Heterotheca grandiflora is a tall, bristly, glandular plant exceeding a meter (40 inches) in height and densely foliated in hairy to spiny toothed or lobed leaves. Leaves are smaller and more widely spaced toward the top of the stem, which is occupied by an inflorescence of bright yellow daisy-like flower heads. The disc and ray florets drop away to leave a spherical head of achenes, each with a long white pappus.


The sweet potato or sweetpotato (Ipomoea batatas) is a dicotyledonous plant that belongs to the bindweed or morning glory family, Convolvulaceae. Its large, starchy, sweet-tasting tuberous roots are used as a root vegetable. The young shoots and leaves are sometimes eaten as greens.  Cultivars of the sweet potato have been bred to bear tubers with flesh and skin of various colors. Sweet potato is only distantly related to the common potato (Solanum tuberosum), both being in the order Solanales. Although darker sweet potatoes are often referred to as "yams" in parts of North America, the species is not a true yam, which are monocots in the order Dioscoreales.
Sweet potato is native to the tropical regions of the Americas. Of the approximately 50 genera and more than 1,000 species of Convolvulaceae, I. batatas is the only crop plant of major importance—some others are used locally (e.g., I. aquatica "kangkong"), but many are poisonous. The genus Ipomoea that contains the sweet potato also includes several garden flowers called morning glories, though that term is not usually extended to I. batatas. Some cultivars of I. batatas are grown as ornamental plants under the name tuberous morning glory, and used in a horticultural context.


The Oxytropis lambertii plant is one of the locoweeds most frequently implicated in livestock poisoning. The toxin is called swainsonine. Research suggests that the plant itself may not be toxic, but becomes toxic when inhabited by endophytic fungi of the genus Embellisia, which produce swainsonine.


It is native to grasslands in the Canadian Prairie  of central Canada and in the mid-west and Great Plains of the United States.


Asparagus asparagoides grows as a herbaceous vine with a scrambling or climbing habit which can reach 3 m (10 ft) in length. It has shiny green leaf-like structures (phylloclades) which are flattened stems rather than true leaves. They measure up to 4 cm long by 2 cm wide. The pendent white flowers appear over winter and spring, from July to September. It is rhizomatous, and bears tubers which reach 6 cm (2.4 in) by 2 cm (1.8 in) in size.


Asparagus asparagoides, commonly known as bridal creeper, bridal-veil creeper, gnarboola, smilax or smilax asparagus, is a herbaceous climbing plant  of the family Asparagaceae native to eastern and southern Africa. Sometimes grown as an ornamental plant, it has become a serious environmental weed in Australia and New Zealand.


Calochortus tolmiei is a North American species of flowering plant in the lily family known by the common names Tolmie's star-tulip and pussy ears. It was discovered by and named for Dr. William Fraser Tolmie.
It is native to the west coast of the United States: Washington, Oregon, and northern California as far south as Santa Cruz County, though it is now apparently extinct in Washington. It is a common member of the flora in several types of habitat.


Calochortus tolmiei is a perennial herb producing a slender stem, branched or unbranched, to 40 centimeters in maximum height. There is a basal leaf up to 40 centimeters long which does not wither at flowering, and generally a smaller leaf farther up the stem.
The inflorescence is a solitary bloom or a cluster of bell-shaped flowers. Each has white to pale pink or purple petals, each up to 2.5 centimeters long, and three narrower sepals beneath. The petals are usually very hairy on their inner surfaces, and may be fringed with long hairs as well.
The fruit is a winged capsule 2 or 3 centimeters long containing several dark brown seeds.


Licorice fern was chewed for flavor by numerous Native American groups, including the Squamish, Shishalh, Comox, Nuxalk, Haida, and Kwakwaka'wakw. The rhizomes were also usually used medicinally as a treatment for the cold and sore throats.


Polypodium glycyrrhiza, commonly known as licorice fern, many-footed fern, and sweet root, is a summer deciduous fern native to western North America, where it is found in shaded, damp locations.
Spores are located in rounded sori on the undersides of the fronds, and are released in cool weather and high humidity.


Licorice fern does not grow its fronds from a centralized location; this is in contrast to other ferns that grow their fronds from the same spot. The name Polypodium refers to this characteristic; it means "many-footed." The fronds are once-divided and triangular in shape, with finely-toothed margins and pointed leaflets. They are usually at least one foot in length, but may grow to be over two feet long. They also display parallel venation. The rhizome is creeping and the fronds appear to have random placement, originating at various points. The rhizome appears reddish-brown, and has a sweet licorice flavor. Since it is a fern, P. glycyrrhiza reproduces by spores; the spores grow in a pattern of spots on the undersides of the leaves. These sori may be oval in immaturity. Licorice fern may grow over the ground, rocks, or as an epiphyte.
The species is not closely related to the flowering plant from which the commercial product licorice is derived (Glycyrrhiza glabra).


Ficus aurea, amongst other related Ficus species, has been a source of bark for preparing amate, the bark paper used for codices in the Mesoamerican civilizations. The oldest example dates back to 75 CE and was found in a shaft tomb culture site in Huitzilapa, Jalisco in Mexico.
The fruit of Ficus aurea is edible and was used for food by the Native Americans and early settlers in Florida; it is still eaten occasionally as a backyard source of native fruit. The latex was used to make a chewing gum, and aerial roots may have been used to make lashings, arrows, bowstrings and fishing lines. The fruit was used to make a rose-coloured dye. F. aurea was also used in traditional medicine in The Bahamas and Florida. Allison Adonizio and colleagues screened F. aurea for anti-quorum sensing activity (as a possible means of anti-bacterial action), but found no such activity.
Individual F. aurea trees are common on dairy farms in La Cruz, Cañitas and Santa Elena in Costa Rica, since they are often spared when forest is converted to pasture. In interviews, farmers identified the species as useful for fence posts, live fencing and firewood, and as a food species for wild birds and mammals.
Ficus aurea is used as an ornamental tree, an indoor tree and as a bonsai. Like other figs, it tends to invade built structures and foundations, and need to be removed to prevent structural damage. Although young trees are described as "rather ornamental", older trees are considered to be difficult to maintain (because of the adventitious roots that develop off branches) and are not recommended for small areas. However, it was considered a useful tree for "enviroscaping" to conserve energy in south Florida, since it is "not as aggressive as many exotic fig species," although it must be given enough space.


Ficus aurea, commonly known as the Florida strangler fig (or simply strangler fig), golden fig, or higuerón, is a tree in the family Moraceae that is native to the U.S. state of Florida, the northern and western Caribbean, southern Mexico and Central America south to Panama. The specific epithet aurea was applied by English botanist Thomas Nuttall who described the species in 1846.
Ficus aurea is a strangler fig. In figs of this group, seed germination usually takes place in the canopy of a host tree with the seedling living as an epiphyte until its roots establish contact with the ground. After that, it enlarges and strangles its host, eventually becoming a free-standing tree in its own right. Individuals may reach 30 m (100 ft) in height. Like all figs, it has an obligate mutualism with fig wasps: figs are only pollinated by fig wasps, and fig wasps can only reproduce in fig flowers. The tree provides habitat, food and shelter for a host of tropical lifeforms including epiphytes in cloud forests and birds, mammals, reptiles and invertebrates. F. aurea is used in traditional medicine, for live fencing, as an ornamental and as a bonsai.


Ficus aurea is a tree which may reach heights of 30 m (98 ft). It is monoecious: each tree bears functional male and female flowers. The size and shape of the leaves is variable. Some plants have leaves that are usually less than 10 cm (4 in) long while others have leaves that are larger. The shape of the leaves and of the leaf base also varies—some plants have leaves that are oblong or elliptic with a wedge-shaped to rounded base, while others have heart-shaped or ovate leaves with cordate to rounded bases. F. aurea has paired figs which are green when unripe, turning yellow as they ripen. They differ in size (0.6–0.8 cm [0.2–0.3 in], about 1 cm [0.4 in], or 1.0–1.2 cm [0.4–0.5 in] in diameter); figs are generally sessile, but in parts of northern Mesoamerica figs are borne on short stalks known as peduncles.


Talinum paniculatum is often grown as an ornamental plant. Cultivars include 'Kingwood Gold', 'Limón', and 'Variegatum'.
The leaves are edible and have been used in traditional medicine in Asia.
Used in home medicine as a diuretic, healing, emollient, vulval and anti-infective, it is also consumed in salads.


Talinum paniculatum is native to the southern United States, much of Latin America (such as Paraguay and Uruguay) and the Caribbean. It has been introduced notably in Africa and Asia.


T. paniculatum bears tuberous roots and panicles of flowers and produces tiny, jewel-like fruits. Its peculiarity is its very long root, of orange colour , that reaches about 80 centimeters. It is a very bad herb in crops, and it proliferates very easily, since it roots very easily, even after it has been plucked and if it has any part of the root in contact with the soil. The plant as a whole can reach almost 2 meters high measured from the soil surface, where after maturity, its brown seeds (in abundance), spread easily through the surrounding area.


Wisteria sinensis clings to supporting plants or man-made structures by counterclockwise-twining stems. The leaves are shiny, green, pinnately compound, 10–30 cm in length, with 9-13 oblong leaflets that are each 2–6 cm long. The flowers are white, violet, or blue, produced on 15–20 cm racemes before the leaves emerge in spring. The flowers on each raceme open simultaneously before the foliage has expanded, and have a distinctive fragrance similar to that of grapes. Though it has shorter racemes than Wisteria floribunda (Japanese wisteria), it often has a higher quantity of racemes. The fruit is a flattened, brown, velvety, bean-like pod 5–10 cm long with thick disk-like seeds around 1 cm in diameter spaced evenly inside; they mature in summer and crack and twist open to release the seeds; the empty pods often persist until winter. However seed production is often low, and most regenerative growth occurs through layering and suckering.
All parts of the plant contain a glycoside called wisterin which is toxic if ingested and may cause nausea, vomiting, stomach pains, and diarrhea. Wisterias have caused poisoning in children of many countries, producing mild to severe gastroenteritis.


Wisteria sinensis, commonly known as the Chinese wisteria, is a species of flowering plant in the pea family, native to China, in the provinces of Guangxi, Guizhou, Hebei, Henan, Hubei, Shaanxi, and Yunnan. Growing 20–30 m (66–98 ft) tall, it is a deciduous vine. It is widely cultivated in temperate regions for its twisting stems and masses of scented flowers in hanging racemes, in spring.


The brown shrike (Lanius cristatus) is a bird in the shrike family that is found mainly in Asia. It is closely related to the red-backed shrike (L. collurio) and isabelline shrike (L. isabellinus). The genus name, Lanius, is derived from the Latin word for "butcher", and some shrikes are also known as "butcher birds" because of their feeding habits. The specific cristatus is Latin for "crested", used in a broader sense than in English. The common English name "shrike" is from Old English scríc, "shriek", referring to the shrill call.
Like most other shrikes, it has a distinctive black "bandit-mask" through the eye and is found mainly in open scrub habitats, where it perches on the tops of thorny bushes in search of prey. Several populations of this widespread species form distinctive subspecies which breed in temperate Asia and migrate to their winter quarters in tropical Asia. They are sometimes found as vagrants in Europe and North America.


The brown shrike is a migratory species and ringing studies show that they have high fidelity to their wintering sites, often returning to the same locations each winter. They begin establishing wintering territories shortly after arrival and their loud chattering or rattling calls are distinctive. Birds that arrive early and establish territories appear to have an advantage over those that arrive later in the winter areas. The timing of their migration is very regular with their arrival in winter to India in August and September and departure in April. During their winter period, they go through a premigratory moult. Their song in the winter quarters is faint and somewhat resembles the call of the rosy starling and often includes mimicry of other birds. The beak remains closed when singing and only throat pulsations are visible although the bird moves its tail up and down while singing.
The breeding season is late May or June and the breeding habitat includes the taiga, forest to semi-desert where they build a nest in a tree or bush, laying two to six eggs.
They feed mainly on insects, especially Lepidoptera. Like other shrikes, they impale prey on thorns. Small birds and lizards are also sometimes preyed upon. A white-eye (Zosterops) has been recorded in its larder. They typically look out for prey from a perch and fly down towards the ground to capture them.


Most of the range is occupied by the nominate subspecies. In the southern part of the range, L. a. gravirostris, which has a longer bill - especially in males - and tail, is only found on mountaintops of the San Gabriel Mountains to San Diego County. Birds on Mount Pinos are somewhat intermediate. mtDNA cytochrome b and ATP synthase subunit 6 sequence data confirms this arrangement and also suggests that the Mount Pinos birds are closer to L. a. gravirostris (Alexander & Burns, 2006). Apparently, the larger bill of the southern subspecies is an adaptation for being better able to feed on the large, spiny cones of Coulter pines (Pinus coulteri). Some taxonomic authorities, including the American Ornithological Society, continue to place this species in the genus Picoides.


The range of the white-headed woodpecker stretches in the mountains from British Columbia through southern California. They form nests in dead trees or snags and reproduce once per year.


It is a succulent plant forming basal rosettes of waxy leaves. The leaves are oval or spoon shaped and up to 3 centimeters long, with smaller ones occurring farther up the stem. The leaves are green to blue green to red tinged or all red. The inflorescence is an erect, sometimes flat-topped array of many flowers. The flowers have white petals tinged with green, yellow, or orange. It typically blooms from May to June.
Though it is not an obligatory host, it is described as a beneficial organism for the Euptoieta claudia butterfly.


Sedum obtusatum is a species of flowering plant in the family Crassulaceae known by the common name Sierra stonecrop. It is native to the Sierra Nevada and adjacent high mountain ranges of California, its distribution extending north into Oregon and east into Nevada. It grows in rocky mountain habitat.


The roots have occasionally been used as a culinary substitute for anise. This species was also used historically by Native Americans as a medicinal herb.


Osmorhiza longistylis, commonly called long-styled sweet-cicely or longstyle sweetroot, is an herbaceous plant in the family Apiaceae. It is native to North America, where it is found from the Rocky Mountains east to the Atlantic Coast, in Canada and the United States. Its natural habitat is in forests with fertile soil, often in areas of loam and dappled sunlight. It can be found in areas of high or average quality natural communities, and does not tolerate intense disturbance.
It is an herbaceous perennial that grows to two and a half feet tall. It produces umbels of small white flowers in late spring and early summer. The crushed plant has a distinct scent of anise.
