A new species of Sedum from Jiangxi:Sedum fluviale
[Objective]During a survey of forest germplasm resources in the Yangjifeng National Nature Reserve in northeastern Jiangxi,China,in 2021,the authors discovered a plant belonging to the Crassu-laceae family and Sedum L.genus.This species differed from previously reported plants of the same ge-nus,and this paper discusses and determines its taxonomic status.[Methods]Multiple populations in Yangjifeng were tracked,and detailed observations and morphological comparisons were conducted at dif-ferent phenological stages to distinguish commonalities and unique traits.Additionally,its national distri-bution was determined through literature review and specimen examination.[Results]The species had a lotus-shaped nutritive branch in the seedling stage,which was most similar to Sedum subtile Miq.Distin-guishing features included well-developed and trinodal sterile branches,5 to 16 flowers per branch on the flower stem,and spatulate-lanceolate bracts in the former,while the latter had slender sterile branches with alternate or opposite leaves,3 to 5 flowers per branch on the flower stem,and linear bracts.[Conclusion]The study indicated that this was a new species,and was named Sedum fluviale B.Chen &Z.W.Zhu.It was specifically found in stream environments and had a broad distribution,including prov-inces such as Jiangxi,Zhejiang,Fujian,Anhui,Hunan,and Guizhou.There had been numerous instances of misidentifications in the past.The holotype specimen was stored at the Shanghai Chenshan Herbarium(CSH).
