Sedum taishunense (Crassulaceae), a New Species from Zhejiang, China

Sedum taishunense X.X. Chen, X. Liu & Y.L. Xu (Crassulaceae) is described as a new species from Taishun County, Zhejiang Province, China. Based on morphology, S. taishunense should be placed in sect. Sedum due to the presence of adaxially gibbous carpels. It is morphologically similar to S. lipingense, S. kawaraense and S. shunhuangense, but differs from them by having larger rosulate leaves, fertile stem leaves and primary bracts; inflorescence with multiple flowers; spatulate sepals; ovules 16–24 per carpel; and seed surface with narrow elliptical or scale-like tuberculae. The systematic position of S. taishunense was assessed using the internal transcribed spacer (ITS) region of nuclear ribosomal DNA. Phylogenetic analysis supported S. taishunense as sister to S. makinoi with high support values (UFBS/ PP/ SH-aLRT) 98.5/1/99.
