Descriptions

Morphology General Habit
Perennial. Stolons present. Basal innovations flabellate. Culms geniculately ascending; 50-100 cm long. Leaf-sheaths glabrous on surface. Ligule a ciliate membrane. Leaf-blades 5-10 cm long; 2-5 mm wide. Leaf-blade surface glabrous, or pubescent; hairy abaxially, or on both sides.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Peduncle glabrous. Racemes 3-9; digitate; unilateral; 6-9 cm long. Rhachis subterete; scabrous on surface. Spikelet packing broadside to rhachis; regular. 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; 3-3.7 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent; obtuse.
Fertile
Spikelets comprising 1 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 3-3.7 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent; obtuse.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; reaching apex of florets; thinner than fertile lemma; gaping. Lower glume lanceolate, or ovate; 1.5-2.5 mm long; 0.6-0.7 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein scabrous. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate, or ovate; 3.2-3.7 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume primary vein scabrous. Upper glume lateral veins absent. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Fertile lemma elliptic, or obovate; laterally compressed; 3-3.7 mm long; cartilaginous; keeled; 3 -veined. Lemma midvein pubescent. Lemma margins pubescent. Lemma apex obtuse; awned; 1 -awned. Principal lemma awn subapical; 3.5-7 mm long overall. Apical sterile florets 2-3 in number; barren; in a clump; cuneate; 1.5-2.8 mm long. Apical sterile lemmas glabrous, or pubescent; adorned on keel; truncate; awned; 1 -awned. Apical sterile lemma awns 3-4 mm long; 2-3 per spikelet in number.
