Ctenopteris

Ctenopteris is a defunct genus of ferns in the family Polypodiaceae. The name is derived from two Greek words: ktenos, "comb", and pteris, "fern".

The name "Ctenopteris" can no longer be used because its type species, Ctenopteris venulosa has been transferred to Prosaptia. Because Ctenopteris is polyphyletic, some of its species were not transferred to Prosaptia with the type species. For these, the name Ctenopteris has been used provisionally, pending their reassignment to other genera.
