Strawcolored Flatsedge

Cyperus strigosus L.

Comments

provided by eFloras
Cyperus strigosus is usually among the more common Cyperus species throughout its range. Small individuals flowering the first year may be difficult to distinguish from C. polystachyos, C. odoratus, C. erythrorhizos, and C. esculentus, which may be sympatric. Cyperus strigosus has trigonous achenes and three stigmas, unlike C. polystachyos; C. strigosus has flattened spikelets, unlike the subcylindric ones of C. odoratus; C. strigosus has floral scales usually 3 mm or more, unlike the smaller (1.2–1.5 mm) ones of C. erythrorhizos; C. strigosus has deciduous floral scales and a cormlike stem base with stolons, unlike C. esculentus.

Cyperus strigosus appears to be closely related to the neotropical C. camphoratus Liebmann; both species have deciduous floral scales and deciduous spikelets (G. C. Tucker 1994). Plants segregated as C. stenolepis cannot be distinguished consistently from C. strigosus on any single charcter, rather they appear to be merely large individuals of C. strigosus with long floral scales and frequently septate inflorescence bracts (M. L. Horvat 1941).

Cyperus strigosus

provided by wikipedia EN

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.[1][2] 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.[3]

Introduced populations occur in Bulgaria, France, Italy, Spain and Bangladesh.[1]
