Ligule 0.5-2 mm, entire, rounded, glabrous throughout. Leaf-blade 1.5-9 cm × 3-4 mm, flat or folded, soft, glabrous, often crinkled when young; margins sparsely, minutely scabrid, tip rounded to blunt point. Culm 3-20 cm, erect, spreading or prostrate, internodes glabrous. Panicle 2-10 cm, usually open, erect; branches smooth to sparsely scabrid, spreading to deflexed after anthesis.
