Taxonomic identities of Coelogyne roseans , C. chen‐tsii and C. niana (Coelogyninae, Orchidaceae)

The taxonomic identities of Coelogyne roseans (= Pholidota roseans ) and C. niana (= P. niana ) have long been misunderstood. Our findings indicate that C. chen‐tsii (= P. longipes ) is conspecific with C. niana , consequentially C. chen‐tsii is reduced to a synonym of C. niana . Although C. roseans and C. niana are closely related and frequently confused, we have clarified their taxonomic distinctions, which primarily lie in the morphology of the lip and column and we have emended descriptions of the two species.
