Abstract
Chiloschista densiflora (Orchidaceae), a new record of flora of China, is described and illustrated based on materials from Motuo, Xizang. Morphologically, Chiloschista densiflora is characterized by middle lobe with a pubescent callus ranging from base to apex, two conical calli at base, short and stocky column.
