Abstract

A new species Arundinella namprikensis in the genus Arundinella supported by both morphological and molecular evidences, from the mountains of Sikkim Himalaya is described and illustrated. This species maintains its uniqueness from morphologically allied species A. nepalensis and A. cochinchinensis by possessing smooth and glabrous rhizomes, glabrous culm node, 5–7-veined lower and upper glumes, bisexual lower floret and the lower lemma almost always with 7 veins. Phylogenetic analysis of nuclear ITS sequences strongly supported the distinctiveness of A. namprikensis by forming a well-defined clade within Arundinella with its accessions sufficiently away from its close relatives, A. nepalensis and A. cochinchinensis. Information on its phenology, habitat, distribution and additional specimens examined are provided.

Arundinella (Arundinelleae, Panicoideae, Poaceae) 的新发现：来自锡金喜马拉雅山的一个新物种的形态学和分子证据

本报告描述并说明了来自锡金喜马拉雅山的 Arundinella namprikensis 属中的一个新种 Arundinella namprikensis，该种得到了形态学和分子学证据的支持。nepalensis 和 A. cochinchinensis 的独特性，其根状茎光滑无毛，秆节无毛，下部和上部颖片有 5-7 条脉，下部小花两性，下部外稃几乎总是有 7 条脉。核 ITS 序列的系统发育分析有力地支持了 A. namprikensis 的独特性，它在 Arundinella 中形成了一个定义明确的支系，与其近亲 A. nepalensis 和 A. cochinchinensis 之间有足够的距离。本文提供了有关其物候学、生境、分布和其他标本的信息。

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.
