    Habit
    Perennial; caespitose. Butt sheaths pallid. Culms geniculately ascending; 15-30 cm long. Leaf-sheaths open for most of their length. Ligule an eciliate membrane; 2.5-4 mm long; acute. Leaf-blades 3-6 cm long; 1.5-2.5 mm wide. Leaf-blade surface glabrous.
    Inflorescences
    Inflorescence a panicle. Panicle contracted; linear; 6-10 cm long. Primary panicle branches appressed; bearing 3-4 fertile spikelets on each lower branch. Panicle branches scaberulous; rough distally. Spikelets solitary. Fertile spikelets sessile, or pedicelled.
    Spikelets
    Spikelets comprising 3-4 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; compressed slightly; 6-7 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent.
    Fertile
    Spikelets comprising 3-4 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; compressed slightly; 6-7 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent.
    Glume
    Glumes persistent; shorter than spikelet. Lower glume lanceolate; 1.6-2.2 mm long; 0.5-0.66 length of upper glume; membranous; purple; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume oblong; 2.8-3.2 mm long; 0.75 length of adjacent fertile lemma; membranous; purple; without keels; 3 -veined. Upper glume apex acute.
    Florets
    Fertile lemma ovate; 3.5-4 mm long; membranous; much thinner above; purple; without keel; 5 -veined. Lemma lateral veins obscure; stopping well short of apex. Lemma surface pilose; hairy below; hairy on veins. Lemma apex acute. Palea 2 -veined. Palea keels scabrous; ciliate; adorned with hairs below. Apical sterile florets resembling fertile though underdeveloped.
