Description
Oplismenus setarius is a perennial grass.
"Creeping perennial; upright culms 1.5-3.5 dm tall, geniculate, nodes appressed pubescent or glabrous, internodes striate, puberulent, pubescent, or glabrous. Leaves cauline; blades ovate to lanceolate, 2-6 cm long, 2-20 mm wide, upper surface densely nerved centrally, pubescent, lower surface occasionally conspicuously septate, puberulent, margins ciliate, conspicuously shorter than internodes; ligules, membranous, ciliate, 0.51-.5 mm long; collars pubescent.

Grain yellowish, oblong to ellipsoid, 2-2.2 mm long."[2]
Distribution
This species ranges from eastern North Carolina to Florida, then west to Arizona and Texas. It's also located throughout the Caribbean and Central America to central South America.[1]
Ecology
Habitat
O. setarius occurs in moist or wet loamy soil, from loamy humus to sandy loam.[3] It also seems to prefer partially to deeply shaded light conditions.[3] It can be found in mesic woodlands, live oak and mixed hardwood hammocks, pine flatwoods, and situations near water, like woodland floodplains and bordering swamps or creeks.[3] It also occurs in disturbed habitat, including trailsides, roadsides, common use areas, and railways.[3]
Phenology
This plant flowers from August to October.[1]
Fire ecology
Populations of Oplismenus setarius have been known to persist through repeated annual burning.[4]
