Plants perennial; usually cespitose, rarely stoloniferous. Culms
to 135 cm. Sheaths mostly glabrous; ligules 0.7-1 mm, erose to lacerate;
blades to 45 cm long, to 15 mm wide, with basal hairs, otherwise usually
glabrous, occasionally scabrous. Panicles digitate, with (4)8-28 evidently
distinct and easily separable branches; branches (5)8-20 cm, flexible,
usually more or less spreading, sometimes drooping, averaging 12 spikelets per
cm. Spikelets strongly imbricate, with 1 bisexual and usually 2 sterile
florets. Lower glumes 1-2.5 mm; upper glumes 1.9-3.5 mm; lowest
lemmas 1.5-2.8 mm long, 0.5-0.9 mm wide, elliptic, strongly laterally compressed,
margins conspicuously hairy for most of their length, hairs 1-3 mm, strongly divergent,
keels densely appressed pubescent, not or only minutely bilobed, apices awned,
awns 1.4-4.8 mm; second florets 1-1.6 mm, cylindrical to narrowly turbinate,
shortly bilobed, lobes less than 1/5 as long as the lemmas, awned from the sinuses,
awns 1.7-4 mm; third florets often enclosed by the first sterile florets,
0.5-0.9 mm, turbinate or flabellate, as long as or longer than the subtending
rachilla internodes, sometimes inflated apically, unawned. Caryopses about
1 mm long, about 0.5 mm wide. 2n = 72.
The range of Chloris elata lies primarily to the south of the Flora
region, extending from southern Florida and the Caribbean islands to Peru
and Argentina.
