Carex poculisquama $K{\ddot{u}}k$., recorded only in the literature in Korea, was confirmed to be distributed in limestone zones in the country. Carex poculisquama is most similar to species in the section Occlusae, such as C. ligulata Nees, but it differs in its rhombic-elliptic perigynium and by the presence of short hairs on the veins of its utricles. We provide here a description, illustrations, and photographs of C. poculisquama and a key to the species.
