Description :

• Perennial, tufted, basal sheaths sometimes swollen into bulbs
• Leaf blade expanded or almost filiform; ligule an unfringed membrane
• Inflorescence a panicle, contracted, spike-like, dense and cylindrical, often interrupted; spikelets solitary, pedicelled
• Spikelet 3.5-4.0 mm long, shining, laterally compressed, disarticulating above glumes; glumes ± equal to unequal, ± equal to longer than spikelet, lower sometimes shorter than spikelet, herbaceous, oblanceolate, linear or lanceolate-linear, acute, keeled, hairy or glabrous, with hyaline margins, sometimes mucronate; lower glume usually 1-nerved; upper glume 1-3-nerved
• Florets 2-4, bisexual or uppermost floret reduced and sterile; lemma 3-5 mm long, longer than glumes, similar in texture to glumes, 3-nerved, keeled, acute to acuminate, entire, sometimes with a mucro or awned (usually minute); palea projecting and conspicuous in mature spikelet, linear or narrowly lanceolate, subacute, 2-keeled, 2-toothed, thinner in texture than lemma, hyaline
• Lodicules 2, hyaline, glabrous
• Stamen 3
• Ovary glabrous; styles distinct, plumose
• x = 7 (aneuploids, high polyploidy)
