Characteristics

Densely caespitose perennial; culms (30–)55–110 cm. high, slender, somewhat wiry, often purple tinged above each node.. Leaves mostly basal, the sheaths usually conspicuously silky pubescent, sometimes ciliate on the margins, often long-ciliate at the top; blades flat and linear or inrolled and filiform, (14–)18–35(–50) cm. long, 1.5–3 mm. wide, tapering at the base, acuminate.. Panicle narrowly oblong to ovate, (8–)12–18(–30) cm. long, the branches usually ascending and appressed, sometimes spreading.. Spikelets ovate, 2–2.5(–3) mm. long, glabrous, often purple tinged; lower glume ovate, 1/2 as long as the spikelet, 5(–7)-nerved, acuminate; upper glume ovate, 5(–7)-nerved; lower lemma ovate, 5-nerved, male, its palea well developed; upper lemma pale and glossy.
