Asia-Tropical: East Asia: present Pacific Islands: present
Three genera and c. 15 species in East Asia, Malesia and Pacific Islands; one genus in all parts of the moist tropics.
According to Smith et al. (2006) Dryopteridaceae, is almost certainly monophyletic, if Didymochlaena, Hypodematium, and Leucostegia are excluded. Schuettpelz & Pryer (2008) included for the first time all three genera in one analysis. They confirmed the conclusion of Smith et al. (2006), and concluded that Didymochlaena, Hypodematium, and Leucostegia should indeed be segregated from Dryopteridaceae because including them would render that family paraphyletic.
