紫萼景天Guo et S.B. Zhou，前L.H.描述了浙江铅锌矿区特有的一新种-景天科本分类群属于景天组Sect. Sedum（H. Ohba）S.H.基于正面的囊状心皮和果的傅。它表面上类似于S。alfredii Hance和其他三个景天属种在同一地区发现，但与这些其他分类群不同的是花为4瓣。在地理分布、生长习性、物候期、宏观形态、茎叶解剖及种子微形态等方面存在差异。plumbizincicola、黑脉链霉菌S. alfredii和其它相关的景天属植物也有报道。nrDNA内转录间隔区（ITS）序列分析表明：plumbizincicola支持这是一个有别于S. alfredii。
Sedum plumbizincicola X.H. Guo et S.B. Zhou ex L.H. Wu (Crassulaceae), a new species restricted to lead-zinc mining areas in Zhejiang Province, China, is described and illustrated. This taxon belongs to sect. Sedum (H. Ohba) S.H. Fu based on the adaxially gibbous carpels and follicles. It superficially resembles S. alfredii Hance and three other Sedum species found in the same area, but differs from these other taxa in bearing 4-merous flowers. Differences in geographical distribution, growth habit, phenology, macromorphology, leaf and stem anatomy, as well as seed micromorphology among S. plumbizincicola, S. alfredii and other related taxa in the genus Sedum are also reported. nrDNA internal transcribed spacers (ITS) sequences from seven populations of S. plumbizincicola support the recognition of this as a taxonomic entity distinct from S. alfredii.
