摘要

Chroniochilus sinicus L. J. Chen & Z. J. Liu, a new species, is described for the Orchidaceae from Yunnan, China, and accordingly the genus Chroniochilus J. J. Sm. is first reported from China. The new species differs from the allied species C. virescens (Ridl.) Holttum by having much larger leaves (7-10 cm), much longer inflorescences (to 18 cm), tiny bracts, and a cordate-conical lip constricted in its upper portion, with side-lobes 3.5-4.5 mm long.
