{{Short description|Genus of ferns}} {{italic title}} thumb | right | Ctenopteris heterophylla '''''Ctenopteris''''' is a defunct genus of ferns in the family Polypodiaceae. The name is derived from two Greek words: ''ktenos'', "comb", and ''pteris'', "fern".<ref name="quattrocchiI">Umberto Quattrocchi. 2000. ''CRC World Dictionary of Plant Names'' volume I.

Or is it specifically a syntactic compound with the genitive singular κτενός?|date=March 2025}}
The name "''Ctenopteris''" can no longer be used because its type species, ''Ctenopteris venulosa'' has been transferred to ''Prosaptia''.<ref name="parris2009">Barbara S. Parris. 2009. "New genera of Malesian Grammitidaceae". ''Blumea'' '''54'''(1-3):217-219. {{doi|10.3767/000651909X476184}}</ref> Because ''Ctenopteris'' is polyphyletic, some of its species were not transferred to ''Prosaptia'' with the type species. For these, the name ''Ctenopteris'' was used provisionally, pending their reassignment to other genera.<ref name="sundue2010">Michael A. Sundue, Melissa Islam, and Tom A. Ranker. In press.

Edwin Bingham Copeland wrote extensively on ''Ctenopteris'' in the 1940s and 1950s.<ref name="copeland1947">Edwin Bingham Copeland. 1947.
