The collection of Indian Carex in the Kew herbarium has recently been considerably enriched by specimens collected in the Punjab, Sikkim, and Tibet, chiefly by Dr. N. L. Bor. Among them is a remarkable new species. As it is unispicate, this very dark little sedge falls into Kiikenthal's subgenus Primocarex, but, by the frequent occurrence of an empty bract, and even, rarely, an accompanying spike, at a short distance below the usual terminal one, it well illustrates the artificiality of this subgenus. Kiikenthal distinguishes this from the other three subgenera in his treatment (Engl. Pflanzenreich, IV, 20: 1909) simply by its unispicate character ; other and more important characters, such as differences in the shape of the utricle and achene, and accompanying variation in number of stigmas, being entirely disregarded.
