Abstract

Parrya tojibaevii, a morphologically distinct species related to the taxa previously assigned to the genus Pseudoclausia, recognized herein as a section, is described and illustrated. The novelty, known from a few collections, is confined to a small and highly disturbed area around the confluence of Chatkal River with Charvak Reservoir (Western Tian Shan, Uzbekistan) and is morphologically closest to P. gracillima and P. mollissima. The new species can be assessed as critically endangered due to its very narrow and obviously shrinking range and habitat, an easy accessibility of known localities, and a growing threat from the construction of hydroelectric power station, roads and resorts, and also from recreation and grazing.

来自乌兹别克斯坦天山西部的一个高度濒危且分布范围受限的 Parrya 科新物种：Pseudoclausia, comb.来自乌兹别克斯坦天山西部的一个濒危和限制分布区的新物种

Parrya tojibaevii 是一个形态上独特的物种，与之前归属于 Pseudoclausia 属的类群有关，在此被认定为一个科，本文对其进行了描述并绘制了插图。该新种仅见于 Chatkal 河与 Charvak 水库（乌兹别克斯坦，天山西部）汇合处周围的一个高度受干扰的小区域，在形态上与 P. gracillima 和 P. mollissima 最为接近。由于该物种的分布范围和栖息地非常狭窄且明显缩小，已知地点交通不便，水电站、道路和度假村的建设以及娱乐和放牧活动对其威胁日益严重，因此可将该新物种评估为极度濒危物种。

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.
