Carex kagoshimensis, a New Species of Carex (sect. Rhomboidales) from Japan

抄録

Carex kagoshimensis Tak. Shimizu is described as new to science. It is similar to C. laticeps in the shape of the achenes, but differs by having emarginate scales in the staminate inflorescence, plants (except utricle) glabrous, wider leaves (2 to 3 times wider), and utricles ascending and sparsely pubescent. It faintly resembles C. insaniae var. papillaticulmis in the shape of the utricles, but differs by having deep notches on the ridges of the achenes and a strongly curved beak lacking an annular appendage, the emarginate scales of the staminate flowers, numerous utricles (at least 3 times as many) on the lowest spike and smooth bract sheaths. Carex kagoshimensis occurs in Yamaguchi, Miyazaki and Kagoshima prefectures.
