摘要

海棠menchunaensis P.Gyeltshen & M.Hughes产于不丹Punakha地区凉爽的阔叶林。由于它有结节状的习性和两裂的胎盘，它被分配到海棠科。diploclium，与B. picta同属。根据其有限的分布，menchunaensis被世界自然保护联盟(IUCN)红色名录列为极度濒危物种。报道了不丹海棠(Begonia picta)、B. rex、B. roxburghii和B. xanthina的新记录。

ONE NEW SPECIES AND FOUR NEW RECORDS OF BEGONIA (BEGONIACEAE) FROM BHUTAN

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.
