Plants mat-forming, stoloniferous, stolons to 150 cm, often branched, with
well-developed leaves, and (usually) axillary fascicles of closely imbricate leaves.
Culms 10-35 cm, unbranched. Sheaths mostly glabrous, margins sometimes
pilose, keeled; leaves mostly basal, blades of basal leaves 0.5-15
cm long, 1-5 mm wide, glabrous or pilose, with papillose-based hairs near the
base, margins glabrous or pectinate near the base; blades of upper leaves
reduced to obsolete. Rames 1-3, 3-12 cm, straight; internodes 2-2.3
mm. Sessile spikelets (2.2)3-4 mm long, (1.1)1.8-2.2 mm wide, elliptic;
calluses sparsely pubescent; glumes glabrous; lower glumes
5-7-veined, obtuse to truncate, often notched, keels with 1-several, 0.2-0.3 mm
hooklike spines near the base, winged distally; upper glumes 3-veined,
elliptic, acute; anthers of lower florets about 0.3 mm; anthers of upper
florets 1.5-1.7 mm. Pedicels 2.8-3.5 mm long, about 0.5 mm wide at
midlength. Pedicellate spikelets absent or to 3.4 mm, occasionally well-developed.
Caryopses 1.5-2 mm, purple to reddish-brown or brown. 2n = 18.
Eremochloa ophiuroides, an east Asian species, was introduced into the
southeastern United States as a lawn grass about 1920. It is now established along
roadsides and in woods, fallow fields, and dunes in the region. It flowers from
spring to fall, and sporadically at other times. The common name refers to the
appearance of the leafy stolons.
