Abstract

One new species of Ophiopogon, O. guangzhouensis, from Guangdong Province in southern China, is described and illustrated. The new species is similar to O. bockianus, but differs markedly by its pedicel (1.3–1.7 cm long) longer than the stalky part of the floral base, adjacent anthers and filaments all completely connate, and style exerted beyond the tepals. This paper not only details their taxonomic features and relationships among similar species, but also provides data on the habitat and phenology of the new species. Based on critical observations on herbarium specimens (including type material) of nine other similar species, we also demonstrate that O. pseudotonkinensis is conspecific with O. bockianus and O. albimarginatus is synonymous with O. stenophyllus. We therefore reduce O. pseudotonkinensis and O. albimarginatus to the synonymy of O. bockianus and O. stenophyllus respectively.

天门冬科天门冬属的分类学研究 I：天门冬属天门冬（Ophiopogon）和天门冬属天门冬（O. albimarginatus）、天门冬属天门冬（O. pseudotonkinensis）以及中国广东新种天门冬属天门冬（O. guangzhouensis）的特征

本报告描述了产自中国南部广东省的一个新种Ophiopogon，即O. guangzhouensis，并绘制了插图。bockianus 相似，但花梗（长 1.3-1.7 厘米）长于花基部的柄部，相邻的花药和花丝完全合生，花柱位于花被片之外。本文不仅详细介绍了其分类学特征和同类间的关系，还提供了新种的生境和物候数据。基于对标本馆中其他九个相似种标本（包括模式标本）的关键观察，我们还证明 O. pseudotonkinensis 与 O. bockianus 为同种，而 O. albimarginatus 与 O. stenophyllus 为同名。因此，我们将 O. pseudotonkinensis 和 O. albimarginatus 分别归入 O. bockianus 和 O. stenophyllus 的同义类。

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.
