(Michaux) P. Beauv.
|Natural range of Anthaenantia villosa from USDA NRCS Plants Database.|
Synonyms: Anthenantia villosa (Michx.) P. Beauv., orthographic variant
A. villosa can be found in a number of southeastern states including Florida, Georgia, Alabama, South Carolina, North Carolina, Louisiana, Mississippi, and Texas. 
The Anthaenantia genera is endemic to the longleaf pine range from southeastern Virginia to central Florida and west to southeast Texas.
A. villosa is found in longleaf pine regions. This grass excels in more exculsively longleaf pine regions during times of higher levels of needle fall from the canopy.  Mild competition is beneficial to viable seed production for A. villosa, making the species more likely to thrive in a variety of competitive environments.  Habitats that specimens of A. villosa have been recovered from include dry sandy edges of coastal flatwoods, sandy peat of flatwoods, turkey oak sand ridge, open live hammock, savanna, edge of longleaf pinelands, grassy roadside with pine overstory, and mixed woodland  It has become absent in response to agricultural practices in southwest Georgia. It has also shown resistance to regrowth in reestablished savanna communities that were disturbed by agricultural practices. A. villosa does not respond to soil disturbance by clearcutting and chopping in North Florida flatwoods forests.
This species is thought to be dispersed by gravity. 
Populations of Anthaenantia villosa have been known to persist through repeated annual burns.
Anthaenantia villosa is wind-pollinated instead of reliant on insects or other animals for pollination.  A. villosa is a bunchgrass that is used by herbivorous animals, including cattle. It is grazed primarily in the summer, and tends to increase under cattle grazing.
Conservation, cultivation, and restoration
A. villosa should avoid soil disturbance by agricultural practices to conserve its presence in pine communities.
