Conservation status:—The national record of this species is based on a single herbarium specimen collected almost twenty years ago in the north-west and on a few cultivated plants collected recently in southern Vietnam. According to the formal criteria of the Red List IUCN (2022), based on scarcely available data, it may be assessed nationally as Critically Endangered (CR), meeting in Vietnam the following conditions: A2a,c; B1a,b(i-iii,v)+2a,b(i-iii,v); C1+2(i,ii); D1; observed population reduction for 10 years or 3 generation ≥ 80% are not reversible (A2), based on direct observation (a), observed decline of the area of occupancy, and extent of occurrence and habitat quality (b); the area of occurrence Notes:—A series of publications (Liu et al. 2006, Puy & Cribb 2007, Chen et al. 2009, Zhou et al. 2016, Ormerod et al. 2021) declare the occurrence of this species in Vietnam without citing any specimens from the country’s territory. Here we report this rare species based on the only verified herbarium collection known up to now.
