Morphology General Habit
Perennial; caespitose. Culms erect; 4-20 cm long. Leaf-sheaths glabrous on surface. Ligule an eciliate membrane; 1.7-2 mm long. Leaf-blades filiform; 1-8 cm long; 0.6-2.4 mm wide. Leaf-blade surface scabrous; rough adaxially; glabrous. Leaf-blade margins scabrous. Leaf-blade apex acute.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; linear, or lanceolate; dense; 1-4 cm long; 0.2-0.8 cm wide. Primary panicle branches ascending; 0.8-1.5 cm long. Panicle branches scabrous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform; terete; 0.3-2 mm long; scaberulous.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 1.5-2.3 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus bearded. Floret callus hairs 1 length of lemma.
Fertile
Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 1.5-2.3 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus bearded. Floret callus hairs 1 length of lemma.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; reaching apex of florets, or exceeding apex of florets; firmer than fertile lemma; shiny; gaping. Lower glume ovate; 1 length of upper glume; membranous; purple; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume ovate; 1.5-2.3 mm long; 1-1.1 length of adjacent fertile lemma; membranous; purple; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Fertile lemma oblong; 1.5-2 mm long; hyaline; without keel; 5 -veined. Lemma surface pilose. Lemma apex dentate; 4 -fid; truncate; awned; 1 -awned. Principal lemma awn dorsal; arising 0.5 way up back of lemma; geniculate; 2-4 mm long overall; with twisted column. Palea 1 length of lemma; hyaline; 2 -veined.
