Crepidomanes inopinatum var. tamonii (Hymenophyllaceae), a new lowland variety endemic to semi-dry forests in La Réunion

Jean-Yves Dubuisson, Sabine Hennequin, Yannis Robert


Unexpected populations of Hymenophyllaceae ferns were observed and collected at low to middle elevations as epilithic in wet ravines within the semi-dry forest in La Réunion Island. These populations would represent lowland ecotypes of the montane Crepidomanes inopinatum, which is usually restricted to humid rainforests at higher elevations. Because of this unexpected habitat and the dwarfed size of the specimens by comparison to typical populations, we thus describe a new variety for the island.
