Abstract / 摘要 MT翻译 摘要 / 摘要 Abstract(#br)Sedum is the most species-rich and taxonomically complex member of the family Crassulaceae. The genus comprises ca. 420 species, which display notable diversity and homoplasy of growth forms, vegetative and reproductive features traditionally used to delineate crassulacean genera therefore it is impossible to characterize Sedum phenotypically. Artificial nature of Sedum was recognized long time ago and it was characterized as a “catch-all” taxon. The phylogenetic structure of Sedum and its relationship with allied genera are poorly understood. Two hundred twenty three sequences of nuclear ribosomal internal transcribed spacer (85 were obtained in this study) were used to address this question and provide |
