广东景天属(景天科)二新种
Two new species of Sedum(Crassulaceae)from Guangdong,China
摘要
Abstract
Two new species of Crassulaceae,Sedum baiwanense Yan S.Huang&Q.Fan and S.nankunshanense Yan S.Huang&Q.Fan,from Guangdong,China,are described and illustrated here.Phylogenetic analysis based on the internal transcribed spacer(ITS)region of nrDNA suggests that the two new species belong to Acre Clade,and are relative to S.subtile Miq.,S.tianmushanense Y.C.Ho&F.Chai,and S.jiulungshanense Y.C.Ho with high support values(node posterior probabilities=1).With high morphologically differences,we can easily distinguish species in this monophyletic group.关键词
