Descriptions

Morphology General Habit
Perennial; caespitose. Culms erect; 30-60 cm long; wiry. Leaves mostly basal. Ligule an eciliate membrane; 5-10 mm long. Leaf-blades filiform, or linear; 5-10 cm long; 1 mm wide.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; ovate, or pyramidal; 10-20 cm long. Primary panicle branches 2-3 -nate. Panicle branches capillary; flexuous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2 fertile florets; with a barren rhachilla extension. Spikelets lanceolate; laterally compressed; 5-7 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite; pilose; with 2 mm long hairs.
Fertile
Spikelets comprising 2 fertile florets; with a barren rhachilla extension. Spikelets lanceolate; laterally compressed; 5-7 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite; pilose; with 2 mm long hairs.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; exceeding apex of florets; similar to fertile lemma in texture; shiny. Lower glume lanceolate; 5-7 mm long; 1 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein smooth, or scaberulous. Lower glume lateral veins absent. Lower glume apex acute. Upper glume elliptic; 5-7 mm long; 1.5-1.8 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume primary vein smooth, or scaberulous. Upper glume lateral veins absent. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Fertile lemma oblong; 3-4 mm long; membranous; shiny; without keel; 5 -veined. Lemma apex dentate; 2 -fid; awned; 1 -awned. Principal lemma awn dorsal; arising 0.1 way up back of lemma; straight; 2-6 mm long overall. Palea 3-4 mm long; hyaline. Palea keels ciliolate. Palea apex dentate; 2 -fid.
