Characteristics

Perennials, tufted. Leaf blades linear to setaceous, flat or rolled. Inflorescence an open or contracted panicle. Spikelets with 1 floret, bisexual, disarticulating above glumes; rachilla extension absent; glumes ovate to lanceolate, subequal, usually longer than floret, herbaceous to membranous, 3–7-veined, veins linked by veinlets or anastomosing near apex, apex obtuse to acuminate; callus very short, rounded, glabrous; lemma lanceolate to ovate or elliptic, dorsally compressed, leathery to bony, brown or black-brown at maturity, glossy, usually with appressed ascending white hairs, infrequently glabrous, covering sides of palea, apex entire or minutely 2-toothed, awned; awn caducous (rarely persistent), fine, straight, scabrid; palea back exposed between lemma margins. Lodicules 3. Stamens 3, anthers usually bearded at apex. Stigmas 2.

More

Perennials, caespitose or shortly rhizomatous. Culms often branched. Leaves: ligule membranous; blade flat to involute. Inflorescence open or contracted. Glumes equal or slightly unequal, obtuse to acuminate, membranous to firm, usually 3–5-nerved. Callus short, blunt. Lemma terete or laterally compressed, shorter than to about as long as glumes, enclosing palea, shortly notched at apex, 3–5-nerved, glabrous; corona and coma absent; terminal or subterminal awn caducous. Palea shorter than to ±equal to lemma, 2-nerved. Lodicules 2 or 3, hyaline, rather large.
