Morphology General Habit
Perennial; caespitose; clumped loosely. Cataphylls evident. Rhizomes short. Culms geniculately ascending; 20-60 cm long; 0.8-1.7 mm diam.; 2-3 -noded. Leaves mostly basal. Leaf-sheaths smooth; glabrous on surface. Ligule an eciliate membrane; 2-4 mm long. Leaf-blades 10-20 cm long; 2-4 mm wide; pruinose. Leaf-blade surface scabrous; rough adaxially.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; lanceolate, or ovate; 5-10 cm long. Primary panicle branches spreading; whorled at most nodes. Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1(-2) fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 5-7 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus bearded. Floret callus hairs 0.25-0.33 length of lemma.
Fertile
Spikelets comprising 1(-2) fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 5-7 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus bearded. Floret callus hairs 0.25-0.33 length of lemma.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; exceeding apex of florets; firmer than fertile lemma; shiny; recurved at apex. Lower glume lanceolate; 5-7 mm long; 1 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein scabrous. Lower glume lateral veins absent. Lower glume apex acuminate. Upper glume lanceolate; 5-7 mm long; 1.1 length of adjacent fertile lemma; membranous; 1-keeled. Upper glume primary vein scabrous. Upper glume apex acuminate.
Morphology Reproductive morphology Flowers Florets
Fertile lemma ovate; 4.5-6.5 mm long; membranous; without keel; 5 -veined. Lemma lateral veins excurrent. Lemma surface punctate. Lemma apex dentate; 4 -fid; awned; 5 -awned. Principal lemma awn dorsal; arising 0.75 way up back of lemma; geniculate; 15-20 mm long overall; with twisted column. Lateral lemma awns arising on apex of lobes; 1-4 mm long. Apical sterile florets 1 in number; rudimentary. Apical sterile lemmas awned; 1 -awned. Apical sterile lemma awns 5-7 mm long.
