Description
Carex utriculata produces stems exceeding 1 m (3 ft 3 in) in maximum height from a thick network of long rhizomes. The inflorescence is a cylindrical mass of flowers up to about 40 cm (16 in) long with an accompanying leaf-like bract which is generally longer than the flower spike. Each inflorescence bears up to 200 developing fruits, each enclosed in a shiny green, golden, or brown perigynium.
