Note Among the four Crepidomanes taxa recognised in Comoros, the widespread C. bipunctatum is an easily distinguishable species. It displays typical lamina false veins more or less continuous and parallel to margins and the sorus lips are triangular (a unique feature for the Comorian Hymenophyllaceae) (see Figs 2E, 3E). This is also one of the only two Hymenophyllaceae species reported on all the four islands with Didymoglossum kirkii (see Table 2).
