description
Short description Epiphytic; long-creeping filiform rhizomes, rootless and densely covered by dense black trichomes, bearing widely separated fronds; fronds sessile and peltate, up to 6 cm long, mostly round and entire, with false veins parallel to true veins and palmate venation; sori numerous, pantotactic, cylindrical with a truncated mouth.
discussion
Note Didymoglossum hildebrandtii is clearly distinct with round and sessile peltate fronds which seem tightly appressed against the substrate (Fig. 3 C). These features, unique for the family in the region, are shared with the Pacific and Asiatic D. tahitense (Nadeaud) Ebihara & K. Iwats. to which it is evolutionary closely related (Ebihara et al. 2007).
distribution
Global distribution Comoros, Madagascar. Distribution in Comoros Anjouan, Mayotte, Mohéli.
