Bulbophyllumchrysolabium (Orchidaceae, Epidendroideae, Malaxideae), a new species from Yunnan, China

Abstract. Bulbophyllumchrysolabium, a new species belonging to section Racemosae from Yunnan, China is described and illustrated. The species is related to B.orientale and B.morphologorum, but differs by having the following set of characters: obliquely broadly-based triangular petals with a long filiform apex; lip densely glandular papillose and conspicuously ciliolate along margins; lip auricles well developed, narrowly falcate, tapering to a long sharp point at the apex; stelidia subulate and twisted inwards, slightly exceeding operculum. The conservation status of B.chrysolabium is assessed and taxonomic notes are provided.
