中国莎草科最新物种名录和分类纲要

An updated species checklist and taxonomic synopsis of Cyperaceae in China

近年来随着分子系统学研究的开展,中国莎草科内族、属和种的名称以及分类学地位产生了诸多变化,因此需要进行及时的整理以减少使用上的谬误。本文通过收集国内外有关莎草科的分类学文献,结合野外调查和网络数据库(中国数字植物标本馆、全球生物多样性信息网络)中的标本数据,全面整理并更新了中国莎草科物种名录与分类纲要。统计结果显示:中国现有莎草科植物2亚科19族32属932种(世界范围内为2亚科24族95属5,719种)。与《中国生物物种名录(2023版)》相比,本文将翅鳞莎属(Courtoisina)、水蜈蚣属(Kyllinga)、湖瓜草属(Lipocarpha)、扁莎属(Pycreus)和海滨莎属(Remirea)的全部物种归并到莎草属(Cyperus),水葱属(Schoenoplectus)、飘拂草属(Fimbristylis)的部分物种和三肋果莎(Tricostularia undulata)按最新研究结果进行了重新归类,并将长柄果飘拂草(Fimbristylis longistipitata)组合到棒拂草属(Abildgaardia)。中国莎草科植物物种多样性在中国南部亚热带地区属、种数较多;薹草属(Carex)种数最多,为632种,莎草属次之,有84种,分别占比67.8%和9.0%;在国内仅分布1种的属有8个,占比25.0%;在国内外标本数据平台没有标本记录的有67种,需要进行深入调查、采集、研究以确认其分布现状。本文整合了目前最新的分类学研究结果,给出中国现有莎草科植物的名录和分类纲要,并对该科植物的分布情况进行了初步分析,可为中国莎草科分类、系统、进化和生物多样性研究等提供数据基础。

Aims:In recent years,with the development of molecular systematics research,there have been many changes in the names and taxonomic status of tribes,genera and species in the family Cyperaceae in China.Therefore it is necessary to review these changes in order to comprehensively understand the taxonomic status of Chinese Cyperaceae and provide a taxonomic basis for related scientific research.Methods:By reviewing the taxonomic literature of Cyperaceae in China and abroad,combined with examining the specimen data from field surveys and online databases(Chinese Virtual Herbarium,Global Biodiversity Information Facility),we summarized and updated the species checklist and taxonomic synopsis of Cyperaceae in China.Results:The statistical results indicated that there were 932 species of Cyperaceae in 2 subfamilies,comprising of 19 tribes and 32 genera in China(of the 5,719 species of 2 subfamilies,comprising of 24 tribes and 95 genera worldwide,excluding infraspecies).Compared with the Catalogue of Life China 2023 Annual Checklist,all species in Courtoisina,Kyllinga,Lipocarpha,Pycreus and Remirea were combined into Cyperus;some species in the genera Schoenoplectus,Fimbristylis and Tricostularia undulata were reclassified according to the results of the latest molecular phylogenetic analyses;and here we combined Fimbristylis longistipitata into Abildgaardia.The species diversity of Chinese Cyperaceae is relatively higher in the subtropical region of southern China,both at the genus and species levels;Carex and Cyperus had the largest number of species,accounting for 67.8%and 9.0%of Cyperaceae species in China,with 632 and 84 species,respectively;8 genera had only one species distributed in China,accounting for 25.0%of Cyperaceae genera in China;67 species had no specimen record in domestic or foreign specimen data platforms,and further research was needed to confirm their distribution status.Conclusion:This paper integrates the latest taxonomic research results of Cyperaceae,gives a list and taxonomic outline of the existing sedge plants in China,and makes a preliminary analysis of the distribution of them,which will lay the data foundation for taxonomic,phylogenetic,and evolutionary research of the sedge family in China.
