Plants perennial; stoloniferous. Culms to 100 cm, erect. Sheaths glabrous,
scabrous, or partly pilose; ligules erose to ciliate; blades with
basal hairs to 3 mm, otherwise glabrous, scabrous, or sparsely pilose. Panicles
digitate, with 2-9 evidently distinct branches; branches 5-11 cm, spikelet-bearing
almost to the base, averaging 10 spikelets per cm. Spikelets with 1 bisexual
and 1(2) staminate floret(s). Lower glumes 1.2-2.3 mm; upper glumes
2.5-4.1 mm; lowest lemmas 2-5.4 mm long, 0.6-1.2 mm wide, elliptic to obovate,
sometimes ventricose, usually glabrous, midveins scabrous, sides not conspicuously
grooved, margins inrolled, usually glabrous or scabrous, occasionally with a few
scattered hairs, especially distally, apices entire or minutely bilobed, awned,
awns 1-11 mm; second florets 1-2.6 mm long, 0.3-1 mm wide, cylindrical
to narrowly turbinate, apices obtuse to truncate, entire, awned, awns 0.5-7.5
mm; anthers 0.7-1.4 mm. Caryopses 1.5-2.1 mm long, about 0.4 mm
wide, narrowly obovoid to trigonous. 2n = unknown.
Chloris ventricosa, an Australian species, has been found near old woolen
mills in South Carolina and has been cultivated. It is very similar to C.
truncata, but usually has shorter panicle branches. Other differences
include its usually tawny bisexual lemmas and their usually glabrous margins.
