Abstract:

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.
