Cyperus strigosus is a species of sedge known by the common names false nutsedge and straw-colored flatsedge. It is native to the United States, Cuba and Canada, where it grows in wet areas in many habitat types, including disturbed and cultivated areas such as roadsides and crop fields. It is common and sometimes weedy.[http://apps.kew.org/wcsp/namedetail.do?name_id=238655 Kew World Checklist of Selected Plant Families][http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=242357718 Flora of North America] It is a perennial sedge growing up to 70 centimetres tall. The inflorescence is a cluster of many linear-shaped spikelets up to 3 centimetres long each. A few long, leaf-like bracts grow at the base of the spike.[http://ucjeps.berkeley.edu/cgi-bin/get_JM_treatment.pl?7928,8084,8100 Jepson Manual Treatment]
