摘要

Bulbophyllum basiflorum M.K.Li, J.P.Deng & Y.Luo (Orchidaceae) from southeastern Xizang, China, is described as a new species and illustrated. This species is morphologically similar to B. cauliflorum and B. stenobulbon, but can be clearly distinguished from them by having shorter scapes adhering to rhizomes and pseudobulbs, raceme dense with 1 or 2 flowers, petals ovate, lip white with 2 longitudinal ridges, and very short column foot. The new species belongs to Bulbophyllum sect. Desmosanthes.
