Carex rhynchophysa

Carex utriculata is a species of sedge known as Northwest Territory sedge[1] and common yellow lake sedge.[2]


This sedge is native to the northern half of North America, including most all of Canada and the northern United States, and down to montane California.[1] It is also found in northern Europe and northern Asia. It is a common plant in many types of wetland habitat.


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.
