Distribution:— VIETNAM, Lam Dong Province (Dalat Town Area). Pakistan, Nepal, Bhutan, N India, Myanmar, Thailand, Laos, China, Korea, Japan. Conservation status:—The only population of this species discovered in Vietnam occupies less than 500 m 2 of territory and according to the formal Red List IUCN (2022) criteria, it meets in Vietnam with the following conditions: extent of occurrence Notes:—All earlier records of this species for Phu Quoc Island treated in the past as a territory of Cambodia or Vietnam are based solely on one wrongly identified specimen (Ile de Phú Quốc, № 75, Contest-Lacour) housed in the P Herbarium (P00392341) and belonging in fact to C. finlaysonianum Lindley (1833: 164). No more records of this remarkable, easily recognizable species in these countries were reported. In this regard, our discovery is the first to be supported by herbarium material. Studied specimen:— VIETNAM, Lam Dong Province, Dalat Town area, secondary open grassy old coniferous forest and woodlands derived from old Pinus kesiya plantation at an elevation of 1300–1400 m a.s.l., erect terrestrial achlorophyllous aphyllous herb with inflorescences to 30 cm tall and thick rhizome to 25 cm long on a steep grassy slope, very rare, 31 May 2022, L.
