Abstract:
Based on morphological and plastid data, we have described and confirmed that Coptisaustrogaoligongensis distributed in Tongbiguan Provincial Nature Reserve, Yingjiang County, Yunnan Province, is a new species of Coptis. It is distinctly different from C.teetasubsp.teeta and C.teetasubsp.lohitensis with differences mainly reflected in the following features: former leaf segment lobes contiguous to each other, and lateral segments equal to central one; plants without developed stolons; inflorescences with only 1-3 flowers; petals have short claws. Phylogenetic analysis indicated that C.austrogaoligongensis is a sister to C.teetasubsp.teeta and C.teetasubsp.lohitensis.
