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. Panicle narrow, 2-12 cm long, 1.5-2 cm broad; strongly winged-angled, scaberulous; lateral branches 1-10, scaberulous, less than 1cm long with 1-10 spikelets, occasionally pubescent at base of branches and between spikelets. Spikelets second, ovoid to ellipsoid, 2.5-3 mm long excluding wns; pedicels pubescent, less than 0.5 mm long. Frist glume strongly scaberulous keeled, lateral nerved obscure, margins obtuse, 0.2-0.6 mm long, 2nd glume and sterile lemma 3-nerved, pubescent or glabrous, scarious, acute, 2.5-3 mm long, sterile palea absent or rudimentary; fertile lemma and palea nerveless, apiculate to mucronate, 2.5-3 mm long.

Distribution
Ecology
Habitat
O. setarius occurs in moist or wet loamy soil, from loamy humus to sandy loam. [2] It also seems to prefer partially to deeply shaded light conditions. [2] 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. [2] It also occurs in disturbed habitat, including trailsides, roadsides, common use areas, and railways. [2]
Phenology
Flowering and fruiting has been observed in July, August, September, October, and December. [2]
