Nannothelypteris

Distribution

Asia-Tropical: Philippines (Philippines present), Luzon present, Mindanao present, Panay present, Samar present
Malesia: Philippines (Luzon, Panay, Samar, Mindanao).

Taxonomy

A natural group of species closely related to Pronephrium sect. Dimorphopteris, with which it might be united. No transference is here made to Pronephrium because of the uncertain status of the latter.
Copeland's treatment of these species in his Fern Flora of the Philippines is confused because he did not examine details. Some earlier confusion was caused by the inclusion by Cuming of some specimens of Sphaerostephanos lastreoides in his n. 251, together with the type collection of Nannothelypteris philippina.
