Average number of good seeds per gram bulk matter: 469
Average number of good seeds per gram cleaned: 1878
Commercial estimates of seeds per gram: n.a.
Percent seed: 25
Percent live: n.m.
Collection dates: November 8, 22
Collection effort: 20 g in 2 person-hours Collection notes: This species should be collected earlier than when it was for this project, as most of the seed was gone by this time.
Cleaning notes: Bulk seed had most stems removed but included many involucres and bracts. Clean seed was good seed with attached pappus (fluff). To get seed from picked state to bulk (planting) state, simply rubbed the inflorescences between hands to dislodge seeds from involucres.
