Cyperus acuminatus is a common species of sedge known by several common names, including tapertip flatsedge and pale umbrella-sedge. This plant is native to North America, where it is widespread across the Great Plains and the western United States , with scattered populations in the eastern US as well as in Saskatchewan, Tamaulipas and Coahuila.[1][2][3][4]
Cyperus acuminatus is found in wet areas from large rivers to roadside ditches. This is an annual plant with a paper-thin stem approaching 40 centimetres (1 ft 4 in) in height at maximum. It may have a few thin leaves near the base. Its spherical inflorescence is one to two centimeters wide and contains several spikelets each a few millimeters long. Each spikelet has a flat layer of flowers which yield oval-shaped achene fruits, each about one millimeter long.[5]
