Perennial, decumbent-spreading, rooting at lower nodes, to 1 m or more long, glabrous or sparsely pilose, the nodes not villous. Sheaths much shorter than internodes, glabrous to pilose or papillose-pilose, especially on margins; ligules thin, ca 1 mm long; blades lanceolate to obovate, acuminate, rounded and +/- clasping and asymmetrical at base, 5-12 cm long, mostly 5-15 mm wide, scaberulous, finely cross-veined downward. Inflorescences with 2 or more branches from terminal node of stem, the longest panicle 15-26 cm long and 4-5 cm wide, beginning to branch ca 11 cm from base; axillary nodes of stems producing inflorescences; spikelets 3-3.5 mm long, glabrous or sparsely pilose or hirsute; first glume acuminate, one-half to two-thirds as long as spikelet, scabrous on keel; second glume and sterile lemma acuminate, subequal; sterile lemma long-ciliate. Fruits ca 2 mm long, oblong-elliptic, the scars extending downward into very narrow wings. Croat 4228, 7893.

Perennial, +/- erect except at decumbent base, rooting at lower nodes, villous especially at nodes. Sheaths much shorter than internodes, prominently ribbed, villous; blades linear-lanceolate to ovate-lanceolate, acuminate, inequilateral and obtuse to rounded at base, 5-10 cm long, 7-20 mm wide, glabrous or with deciduous stiff trichomes on upper surface. Inflorescences with a few short branches from upper node of stem, the longest panicles 7-12 cm long and 2-4 cm wide, beginning to branch 2.5-5.5 cm from base; axillary nodes of stems usually without visible inflorescences; spikelets 3.5-4 mm long, scabrous on keel of first and second glumes; first glume about two-thirds the length of spikelet, acute to acuminate; second glume much longer than fruit, acuminate to +/- aristate; sterile lemma slightly longer than fruit, long-ciliate, blunt. Fruits oblong-elliptic, ca 2 mm long, dull white. Croat 8351, 12868. Rare, along trails in the forest, mostly on the western side of the island.
