biostudies-literatureUnknown268Yi XWThis study describes a new species of Sedum (Crassulaceae), Sedum qingyuanense sp. nov. discovered in Qingyuan City, Guangdong Province, China. Morphologically, S. qingyuanense resembles S. alfredii and S. emarginatum. The new species may have previously been misidentified as S. alfredii. However, the new species can be readily distinguished from S. alfredii by its creeping sterile stems, opposite leaves, emarginate leaf apices, and smaller sepals. Compared to S. emarginatum, it is differentiated by its creeping sterile stems, smaller sepals, and conspicuous pseudopetioles. Phylogenetic analysis based on the nuclear ribosomal DNA internal transcribed spacer (ITS) region revealed that the new species forms a sister clade to SPhytoKeys45-58https://www.ebi.ac.uk/biostudies/studies/S-EPMC12723398biostudies-literatureSedum qingyuanense (Crassulaceae), a new species from Qingyuan, Guangdong, China.PMC12723398Tang KZeng QGYi XWXie ZYHuang YSFan QXu WShen XGfalseSedum qingyuanense (Crassulaceae), a new species from Qingyuan, Guangdong, China.This study describes a new species of Sedum (Crassulaceae), Sedum qingyuanense sp. nov. discovered in Qingyuan City, Guangdong Province, China.
