Distribution

Xanthocyparis vietnamensis is endemic to Vietnam, being native only to the karst limestone mountains of the Hà Giang Province in northern Vietnam.[2]

Taxonomy

It was first discovered by western scientists only in October 1999 and was shortly thereafter described as a new genus and species, namely Xanthocyparis vietnamensis, closely related to Nootka cypress (Xanthocyparis nootkatensis), which was also transferred to this new genus.[3] Subsequently, Little et al. (2004) pointed out that an earlier genus name Callitropsis had been given to Nootka cypress,[4] but this name was later abandoned in favour of Xanthocyparis.[5][6]

Conservation

Xanthocyparis vietnamensis is designated as an Endangered[7] species, as only 560 individuals are known to exist, on only 10 km2 of habitat.[2]
