Description
C. anceps is a perennial graminoid of the Poaceae family native to North America. [1]
Differentiating between the subspecies, Coleataenia anceps ssp. rhizomata tends to have hairier leaves than C. anceps ssp. anceps. As well, to differentiate between C. anceps ssp. rhizomata and C. rigidula ssp. condensa, the sheaths of ssp. rhizomata vary from sparsely to densely villous, principally near the margin, while ssp. condensa are either completely glabrous or appressed pubescent distally.[2]
Distribution
This weedy graminoid can be found in the United States, from the east coast west to Illinois and Texas. [2]
Ecology
Habitat
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. It is listed as a facultative and facultative wetland species, occurring mainly in wetlands but also occasionally in non-wetlands.[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. [3]
Phenology
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
C. anceps consists of approximately 10-25% of the diet for water birds and terrestrial birds.[4] This species is grazed by cattle and deer, and birds as well as waterfowl eat the seeds.[5]
Conservation and Management
For management, it should be noted that close grazing of this species causes the basal tufts to widely spread as well as the leaves to form a dense cover over the small areas it is found.[5]
Cultivation and restoration
This grassy wwed has been used for restoring regions used for mining, logging, timber roads, and other eroded sites by reintroducing vegetation.[1]
