- relatively large pinnules, which are parallel-sided and often somewhat contracted at the base
- the pinnules are standing obliquely upward and close together (often touching each other)

- the midvein is firm and sunken
- the lateral veins are forked close to the midvein and afterwards again
By far the most of the Pecopteris fossils belong to this species. Rather large leaves (up to 30 cm) occur.
