- the pinnules are elongatedly triangular to trapezium-shaped and they are broadly attached to the axis (like Pecopteris)
- the top of a pinnule is rounded and the leaf margin is lobed
- the pinnules are nearly always somewhat convex
Sometimes seeds are attached to the pinnules, but unfortunatedly we haven't found them.
Complete leaves are forked twice.
