Morphology General Habit
Perennial. Rhizomes short; pachymorph; knotty. Culms erect; 30-60 cm long; firm. Lateral branches lacking, or sparse. Branch complement one; solitary. Leaves cauline; 4-7 per branch. Ligule an eciliate membrane. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades elliptic, or oblong; 10-18 cm long; 25-50 mm wide. Leaf-blade venation with distinct cross veins. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Racemes 1; single; bilateral; 7-15 cm long. Spikelet packing broadside to rhachis; distant. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 6-12 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 20-40 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1.5 mm long; obscured by lemmas. Floret callus evident; 1 mm long.
Fertile
Spikelets comprising 6-12 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 20-40 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1.5 mm long; obscured by lemmas. Floret callus evident; 1 mm long.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; shorter than spikelet. Lower glume ovate; 3-4 mm long; 1 length of upper glume; herbaceous; without keels; 5-7 -veined. Lower glume apex acute. Upper glume ovate; 3-4 mm long; 0.4-0.5 length of adjacent fertile lemma; herbaceous; without keels; 5-7 -veined. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Fertile florets divergent. Fertile lemma obovate; 7-10 mm long; herbaceous; without keel; 11 -veined. Lemma surface pubescent; hairy all along. Lemma apex acute. Palea 1 length of lemma; 6 -veined. Palea keels winged; narrowly winged; ciliolate. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Lodicules 3; obovate; membranous; veined; obtuse. Anthers 6. Stigmas 2; papillose.
