Perennials, erect, caespitose. Flowering culms to 60 cm high. Leaves: basal leaf sheath margins glabrous; ligule a ciliate membrane, 0.7–0.9 mm long; blade flat, linear, 1.5–12 cm long, to 4 mm wide, with smooth margins. Inflorescences paniculate, irregular, open (towards base) or contracted and spiciform (towards apex), 8–20 cm long; primary branches whorled at the lowermost panicle node, not all whorled, equalling or longer than adjacent internodes, appressed in upper half of inflorescence, without spikelets in the lower quarter, with spikelets loosely spaced and fairly even. Spikelets subsessile or pedicellate, 2–2.5 mm long; pedicel 0.6–1 mm long. Glumes: lower glume obscurely oblong, 0.8–1 mm long, truncate, without nerves; upper glume lanceolate, ±equalling spikelet, 2–2.5 mm long. Lemma lanceolate, 2–2.5 mm long, slightly carinate, acute, 1-nerved, pubescent in upper part. Palea slightly shorter than lemma, entire. Anthers 3, 0.8–0.9 mm long. Grain asymmetrically ovate, subterete, to 1.1 mm long, to 0.6 mm wide, to 0.6 mm thick, smooth, pale brown. Embryo ±half as long as grain.
