Abstract

Nitellopsis obtusa (Desv.) J.Groves, the species of charophytes (Characeae, Charales), has a wide distribution from Europe to Asia, and is listed as a threatened species in certain countries. While 19 species of Chara, Nitella, and Tolypella have been documented in Mongolia, N. obtusa has remained unreported. In this study, we provided the first documented occurrence of N. obtusa in Mongolia, specifically from the Khar-Us and Khar Lakes and the connecting Chono Kharaikh River (western Mongolia). Species identification was corroborated by morphological observations and molecular analysis. The majority of specimens examined were sterile, with only a limited number of thalli-bearing oogonia (female reproductive organs). This study presents a detailed account of the morphology, taxonomy, phylogeny, and geographical distribution of N. obtusa in Mongolia.

蒙古钝刺棘蝗（特指）首次记录：国家植物区系新属

钝棘球线虫（Desv.）叶蕨属植物（chareae, Charales），从欧洲到亚洲分布广泛，在某些国家被列为濒危物种。虽然在蒙古已记录有19种查拉、Nitella和Tolypella，但obtusa仍未报道。在这项研究中，我们提供了蒙古首次记录的N. obtusa，特别是在Khar- us和Khar湖以及连接的Chono Kharaikh河（蒙古西部）。形态观察和分子分析证实了物种鉴定。检查的大多数标本都是不育的，只有有限数量的含铊的卵原体（雌性生殖器官）。本文详细介绍了蒙古长尾草的形态、分类、系统发育和地理分布。

期刊介绍： The Journal of Asia-Pacific Biodiversity (previous title was Journal of Korean Nature) is an official journal of National Science Museum of Korea (NSMK) and Korea National Arboretum (KNA). The scope of journal is wide and multidisciplinary that publishes original research papers, review articles, as well as conceptual, technical and methodological papers on all aspects of biological diversity-its description, analysis and conservation, and its application by humankind. This wide and multidisciplinary journal aims to provide both scientists and practitioners in conservation theory, policy and management with comprehensive and applicable information. However, papers should not be submitted that deal with microorganisms, except in invited paper. Articles that are focused on the social and economical aspects of biodiversity will be normally not accepted.
