Abstract

Begonia menchunaensis P.Gyeltshen & M.Hughes is described from the cool broadleaved forest of Punakha District in Bhutan. It is assigned to Begonia sect. Diploclinium because it has a tuberous habit and bifid placentae, and is allied to B. picta. Based on its restricted distribution, Begonia menchunaensis is assessed as Critically Endangered under the IUCN Red List Categories and Criteria. Begonia picta, B. rex, B. roxburghii and B. xanthina are reported as new records for Bhutan.
