Abstract
Sedum jinianum (Crassulaceae) has been treated as a synonym of S. bulbiferum, a widely distributed species in southern China, in Flora of China. However, critical observations on living plants in the wild revealed remarkable morphological distinctions between the two taxa. Sedum jinianum can be readily distinguished from S. bulbiferum by its alternate leaves, shape and size of leaves, and dark green bulbils. The plastomes of S. jinianum are 150,041-150,086 bp in length and exhibit a typical quadripartite structure. Phylogenetic analysis based on complete chloroplast genome data indicates that S. jinianum forms a monophyletic clade, sister to a well-supported clade comprising four S. bulbiferum samples from geographically different populations. These findings support the reinstatement of S. jinianum as an independent species. Since the original holotype of S. jinianum could not be found in the ANUB, a neotype (L. Shen 240510 at ANUB) is designated here, along with an emended species description.
