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

摘要

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.
