Upper glume apex acute.
    Florets
    Fertile lemma oblong; 1.5 mm long; hyaline; without keel; 5 -veined. Lemma lateral veins excurrent. Lemma apex erose; truncate; muticous, or mucronate. Principal lemma awn subapical. Palea 0.9 length of lemma; hyaline; 2 -veined.

    Anthers
    Anthers 0.8-1.4 mm. long.
    Habit
    A stoloniferous perennial, loosely caespitose.
    Culms
    Culms 25-140 cm. tall or even more, erect or geniculately ascending, slender, simple, 3-many-noded.
    Leaf sheaths
    Leaf-sheaths scabridulous towards the mouth.
    Leaf lamina
    Leaf-laminae 5-17 x 0.25-0.6 cm., usually expanded, tapering to a fine point, glabrous, sometimes slightly rigid, scaberulous.
    Inflorescences
    Panicle 5-25 cm. long, up to 2.75 mm. wide, contracted, linear to oblong in outline, straight or slightly curved, sometimes lobed or interrupted.
    Spikelets
    Spikelets 2-2.6 mm. long, widely gaping, pale-green or tinged with purple.
    Glume
    Glumes 1 -nerved, subequal, as long as the spikelet, lanceolate, membranous, acute, scaberulous to scabrous.
    Lemma
    Lemma 1.4-1.6 mm. long, oblong-elliptic when expanded, 5-nerved, apex truncate, all nerves or at least the lateral pairs excurrent into short mucros, rarely with the central nerve excurrent into a short (0.5 mm.) awn; callus glabrous.
