and cattle, requires moist condition, prefers fertile soils, it does not tolerate waterlogging, naturalized, colonizer, a weed of cultivation, excellent drought
resistance, persistent under heavy grazing. Distribution at Sulawesi
Celebes.

Plants annual, rooting at the lower nodes. Culms 50 cm long, decumbent, slender. Sheaths smooth. Ligule 1.5 mm long, an eciliate membrane. Blades 5-10 cm
by 2-6 mm, soft, glabrous to moderately appressed-pilose. Inflorescence composed of racemes. Racemes 2-4, digitate, unilateral, 4-10 cm long. Rachis narrowly winged,
smooth on margins. Spikelets in pairs: fertile spikelets pedicelled, 2 in the cluster. Pedicels unequal. Fertile spikelets comprising 1 basal sterile florets, 1 fertile florets,
