Morphology General Habit
Perennial; caespitose. Basal innovations flabellate. Culms 30-45 cm long. Leaf-sheaths glabrous on surface, or pilose. Ligule an eciliate membrane. Leaf-blades 5-15 cm long; 4 mm wide. Leaf-blade surface scaberulous.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes; deciduous as a whole. Peduncle disarticulating; disarticulating above uppermost sheath. Racemes 8-10; digitate; radiating; unilateral; 10-20 cm long. Rhachis subterete; scabrous on surface. Spikelet packing broadside to rhachis; lax; regular. Raceme-bases filiform; 20-50 mm long. Spikelets solitary. Fertile spikelets sessile.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 3.7-4.3 mm long; falling entire; deciduous with accessory branch structures. Floret callus bearded; obtuse.
Fertile
Spikelets comprising 1 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 3.7-4.3 mm long; falling entire; deciduous with accessory branch structures. Floret callus bearded; obtuse.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes similar; shorter than spikelet; thinner than fertile lemma; gaping. Lower glume lanceolate; 2.7-3 mm long; 0.7-0.8 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein scaberulous. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 3.5-3.8 mm long; 0.8-0.9 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume primary vein scaberulous. Upper glume lateral veins absent. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Fertile lemma lanceolate, or ovate; laterally compressed; 3.7-4.3 mm long; cartilaginous; keeled; 3 -veined. Lemma margins ciliate; hairy above. Lemma apex acute; awned; 1 -awned. Principal lemma awn subapical; 7-11 mm long overall. Apical sterile florets 1 in number; barren; elliptic; 2-2.5 mm long. Apical sterile lemmas acute; awned; 1 -awned. Apical sterile lemma awns 4.5-6.5 mm long; 1 per spikelet in number.
Morphology Reproductive morphology Flowers
Lodicules 2; cuneate; fleshy. Anthers 3. Stigmas 2.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp; ellipsoid; dorsally compressed; trigonous; 2.3 mm long.
Distribution
