Notes on Carex (Cyperaceae) from China (V): new species, combination and subspecies from Zhejiang

Abstract

Recent fieldwork in the Chinese province of Zhejiang revealed new insights into the taxonomy of the genus Carex in this area. Carex honglinii, a new species of Carex sect. Confertiflorae, is described. It differs from C. pseudodispalata in having perigynia broadly obovoid, contracted into a ca. 0.5‒0.7 mm long beak at the apex, and staminate scales acuminate. Carex nemostachys var. subglabra (sect. Confertiflorae) is raised to specific rank and combined as C. subglabra. Eventually, a new subspecies of Carex scopulus (subsp. aristata; sect. Mitratae) is described. This new subspecies differs from the type subspecies in having pistillate scales with a 1‒4 mm long apical scabrous awn, and leaves 1.5‒2.5 wide.

Carex linanensis (sect. Mitratae), a new species of Cyperaceae from Zhejiang, East China

“…Recent ongoing field collections and specimen examinations of Carex in Zhejiang Province, China have resulted in the discovery and description of new species and subspecies ( Lu and Jin 2018a ), as well as some new distribution records ( Lu and Jin 2018b ; Lu et al 2019 ; Zhang et al 2020 ). These findings have contributed to revisions in the genus Carex for the new edition of Flora of Zhejiang ( Jin et al 2020 ; Jin et Lu 2021 ).…”

 Carex malipoensis (Cyperaceae), a new species from southeast Yunnan, China

“…A total of 527 Carex were recorded in Flora of China (Dai et al 2010), the Catalogue of Life China (Chen and Zhang 2018) recorded 593 species, which represents the most complete and update list of the genus in China. The number of species of Carex continues growing in China as more new species have been reported in recent years (Lu and Jin 2018;Zhang et al 2018;Jin et al 2020;Lu et al 2020;Yang and Liu 2020).…”
