A. fissifolius is a perennial grass of the Poaceae family. The leaf blade can be flat or folded with fine hairs along margin near the base, slightly pointed or rounded, and purplish or reddish when mature. The seedhead has 3 slender racemes, 2 at summit and 1 (rarely 2) below.
A. fissifolius can be found in the southeastern United States from Texas to Virginia, in California and Puerto Rico, and was introduced to Hawaii.
A. fissifolius is found in pine flatwoods, sandy forests, fields, roadsides, and lawns.  It has also been found in grassland areas with poor drainage, among other bunchgrasses.  Other observances include loamy sand of longleaf pine oak wiregrass sandhills, wet depressions, mixed swamps, hydric hammocks, and wet clayey sand.
A. fissifolius was found to either increase its occurrence or be unaffected by soil disturbance by roller chopping in south Florida. It has also shown additional growth and sometimes no change in growth in reestablished native south Florida forests that were disturbed by roller chopping. It does not respond to soil disturbance by clearcutting and chopping in North Florida flatwoods forests.
Associated species: Fuirena sp. and Rhynchospora sp.
A. fissifolius occurs more in spots where grazing and trampling were particularly heavy. 
Herbivory and toxicology
A. fissifolius is rated as good forage.  It is grazed all year by various livestock. This species is an invader species that can tolerate heavy grazing and must be subject to grazing to continue growing.
Conservation, cultivation, and restoration
A. fissifolius is designated as a weedy or invasive plant by the Hawaiian Ecosystems at Risk Project, Biological Resources Division. For the most production and efficient harvest by livestock, grazing should be rotated each 30 to 40 days with no more than 50% of the current year's growth grazed.
