摘要

本文介绍了广西一新种南岭景天(Sedum nanlingense)。对其形态特征进行了分析，发现其形态特征与S. onychopetalum和S. kiangnanense基本相似。然而，这个新种的形态在一些重要方面与其他分类群不同，包括它的3瓣花，包含6个雄蕊和3个心皮。基于核DNA内转录间隔序列(ITS)的分子系统发育分析表明南林ense是一个独立的分支，为其分类提供了进一步的支持。系统发育分析表明，该新种与S. onychopetalum和S. kiangnanense亲缘关系较近。

Sedum nanlingense (Crassulaceae), a new species from Guangxi, China

Sedum nanlingense (Crassulaceae), a new species from Guangxi, is described and illustrated here. We analyzed its morphological characteristics, which are largely similar to S. onychopetalum and S. kiangnanense. However, the morphology of this new species differs from other taxa in some important ways, including its 3-merous flowers, which contain six stamens and three carpels. Molecular phylogenetic analysis based on nuclear DNA internal transcribed spacer (ITS) sequences resolved S. nanlingense as a distinct clade, lending further support to its classification. Phylogenetic analysis showed that this new species is closely related to S. onychopetalum and S. kiangnanense.

期刊介绍： Phytotaxa is a peer-reviewed, international journal for rapid publication of high quality papers on any aspect of systematic and taxonomic botany, with a preference for large taxonomic works such as monographs, floras, revisions and evolutionary studies and descriptions of new taxa. Phytotaxa covers all groups covered by the International Code of Nomenclature foralgae, fungi, and plants ICNafp (fungi, lichens, algae, diatoms, mosses, liverworts, hornworts, and vascular plants), both living and fossil. Phytotaxa was founded in 2009 as botanical sister journal to Zootaxa. It has a large editorial board, who are running this journal on a voluntary basis, and it is published by Magnolia Press (Auckland , New Zealand). It is also indexed by SCIE, JCR and Biosis. All types of taxonomic, floristic and phytogeographic papers are considered, including theoretical papers and methodology, systematics and phylogeny, monographs, revisions and reviews, catalogues, biographies and bibliographies, history of botanical explorations, identification guides, floras, analyses of characters, phylogenetic studies and phytogeography, descriptions of taxa, typification and nomenclatural papers. Monographs and other long manuscripts (of 60 printed pages or more) can be published as books, which will receive an ISBN number as well as being part of the Phytotaxa series.
