Dichelachne rara

Rather variable, culms erect, mostly to c. 70 cm high, but occasionally to 1 m or more, typically smooth and glabrous, but not infrequently scabrous or shortly pubescent. Leaves scabrous, glabrous or shortly hairy; blade flat, to 15 cm long, 1–3 mm wide; ligule membranous, truncate, to 1.5 mm long. Inflorescence typically a moderately dense panicle 5–15 cm long, usually with short, erect branches bearing spikelets almost to the base, rarely a rather open panicle with spreading branches; glumes acute to acuminate, sometimes almost hair-pointed, 4.5–6 mm long, subequal; lemma up to 1.5 mm shorter than glumes, smooth to finely scabrous in upper half; awn inserted up to 1 mm (but usually c. 0.5 mm or less) from lemma apex, 10–25 mm long, distinctly once(occasionally twice)-bent, the column differentiated, strongly twisted at maturity. Flowers Oct.–Feb.
