C. anceps is a perennial graminoid of the Poaceae family native to North America. [1]


This weedy graminoid can be found in the United States, from the east coast west to Illinois and Texas. [3]



C. anceps is tolerant of a variety of habitats such as dry sandy soil and standing water regions; however, swamp regions are its ideal habitat, with partial shade. [1]

Specimens of C. anceps have been collected from habitats including upper tidal swamps, edge of rivers, in dune swale, ind rying sandy loam of open flatwoods, burned over cypress swamp, pine flatwoods, moist sands of roadsides, moist sands in hammock clearing, and longleaf pine flatwoods. [4]


once a year the C. anceps flowers, in the fall, and produces its seeds that are germinated in the fall and early winter. [1]

Use by animals

Deer graze on the grass and birds and waterfowl eat the seeds. [1]
