Plants perennial; cespitose to shortly stoloniferous. Culms 10-40 cm. Sheaths glabrous; ligules 0.5-0.8 mm, shortly ciliate; blades to 15 cm long, to 1 mm wide, sometimes with basal hairs, mostly glabrous or scabrous. Panicles with 6-13, evidently distinct branches, these usually digitate, sometimes with a second, poorly-developed whorl just below the terminal branches; branches 4-14 cm, spreading, spikelet-bearing to the base, with 4-7 spikelets per cm; disarticulation at the uppermost cauline node, panicles falling intact. Spikelets with 1 bisexual and 1 sterile floret. Lower glumes 2-2.3 mm; upper glumes 3-3.3 mm; lowest lemmas 1.9-2.7 mm long, 0.5-0.6 mm wide, lanceolate to elliptic, without conspicuous grooves on the sides, mostly glabrous but the margins and keels appressed pubescent with hairs less than 1 mm, apices acute, awned, awns 1.9-5.2 mm; second florets 0.9-1.7 mm, 0.2-0.5 mm wide, narrowly cylindrical, obtuse, bilobed and awned, lobes less than 1/5 as long as the lemmas, awns 2.5-3.5 mm. Caryopses 1.3-1.4 mm long, about 0.4 mm wide, ellipsoid. 2n = 40.

Chloris andropogonoides grows along grassy roadsides and prairie relicts of the coastal plain of southern Texas and northeastern Mexico.
