Plants in small tufts, 25-50 cm. high, glabrous throughout; culms erect or reclining, very slender and wiry, producing from the middle nodes slender branches about equaling the main culm, both this and the branches bearing small, solitary or fascicled panicles from the upper nodes; leaf-sheaths very short, about 1-2 cm. long; blades 1-4 cm. long, 1-2 mm. wide, the upper often reduced to mere points, erect, firm, involute; panicles short-exserted, the lateral often partly included, 1-2 cm. long, 1-2 mm. wide, subracemose; spikelets 1.4-1.6 mm. long, about 0.7 mm. wide, elliptic, rather turgid; first glume about half the length of the spikelet, blunt, nerveless or 1 -nerved; second glume and sterile lemma equal, scarcely exceeding the fruit, 5-nerved; fruit 1.3 mm. long, 0.6 mm. wide.
Type locality: Jamaica.
Distribution: West Indies and Costa Rica to Brazil.
