Plants perennial, creeping stolons, rooting at the nodes. Culms up to 45 cm long. Sheaths glabrous. Ligule 0.5-2 mm long, truncate, erose. Blades 1-5 cm by 2-5 mm,
glabrous. Inflorescence composed of racemes. Racemes 2 or 3, digitate, ascending- erect, 1-7 cm long. Rachis broadly winged, with rounded midrib. Pedicels unequal.
Spikelets in threes: Fertile spikelets pedicelled, 3 in the cluster; comprising 1 basal sterile florets, 1 fertile florets, without rhachilla extensions; elliptic, dorsally
compressed, 1.2-1.6 mm long, falling entire. Glumes dissimilar. Lower glume absent, rarely a minute scarious collar. Upper glume as long as the spikelet, elliptic,
membraneous, without keels, 3-5-nerved, apically anastomosing, surface glabrous, apex acute. Florets: basal sterile florets barren, without significant palea; lemma
elliptic, as long as spikelet, membraneous, 7-nerved, glabrous, acute. Fertile lemma 1.2-1.6 mm long, cartilaginous, without keel; margin flat, apex acute.
