Discusión taxonómica
Enterosora is a small genus of eight species in the wet Neotropics, ranging from southern Mexico to Bolivia and Surinam, and in the Antilles; one or two additional species are known from Africa (Bishop & Smith, 1992), and there may be additional species in Madagascar. The genus is closely related to Ceradenia (Ranker et al., in prep.), and may be the sister group to that. Enterosora, like Ceradenia, is anhydathodous but differs in the often anastomosing veins (free in two of the three Mexican species!), less dissected blades (often subentire to shallowly lobed), in having sori commonly imbedded in thick, spongy, highly aerenchymatous blades, and especially in the absence of whitish, globose glands in the sori.A
