Chloris elata

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.
