摘要

Begonia satrapis C.B. Clarke and B. scutata Wall. are two rare species known from Eastern Himalaya. Begonia satrapis is an endemic of Sikkim and Darjeeling Himalaya, while B. scutata is reported to occur in Sikkim and the adjacent Nepal Himalaya. In this contribution we review their collection history, reassess their present conservation status, and identify various threats to their survival in nature. We found that many of the species' populations have disappeared and the existing ones have considerably shrunk to small sizes. Begonia satrapis was represented by only three scattered populations in the adjoining localities comprising about 40-50 individuals each. Likewise, B. scutata was represented by three populations of about 10-15 individuals each. We suggest urgent ex situ and in situ conservation measures for saving these species front extinction.
