Abstract

Carex tenuirostrata, a new species of C. sect. Confertiflorae, is described from Pingyang and Putuo counties of Zhejiang province, China. It is morphologically similar to C. pseudodispalata, but differs in its androgynous lateral spikes; distended perigynia attenuately contracted into a short beak at the apex; ellipsoid-obovoid achenes contracted into a slender beak at the apex; and long-sheathed lower bracts. Scanning electron microscope (SEM) photographs of the achenes of the new species and C. pseudodispalata are provided for comparison.
