Dendrochilum is a genus of orchids (Orchidaceae), containing between 100 and over 300 species according to different sources.
While many authors would accept about 150 species or so, numerous new taxa have become known in recent decades. Thus, in this text the more split-up approach is followed pending more up-to-date information, as it seems that the very low species numbers are certainly gross overlumping, and while the very high numbers presented by some authors are probably a result of oversplitting, they are likely to be closer to the truth.
