                 Abstract: Based on literature researchꎬ specimen identification and field investigationꎬ we systematically cleared up the
                 early researches of Sedum L. and conducted an overview for the species diversity of Sedum in Guangxi. There are 17
                 species were confirmedꎬ among which six species were newly recorded. The research brief histories of Sedum taxonomy in
                 Guangxi were summarizedꎬ information for S. polytrichoides Hemsl. was revised. Six newly recorded species of Sedum
                 were reported hereꎬ which were S. leblancae Hamet.ꎬ S. lipingense R. B. Zhangꎬ D. Tan & R. X. Weiꎬ S. lungtsuanense

                 photographs for these newly recorded species were provided. The species diversity and the potential utilization of Sedum
                 in Guangxi were discussedꎬ and key for species and the distribution of each taxa in Guangxi were provided. This study
