Culm-internodes terete; smooth. Lateral branches lacking. Leaves mostly basal. Leaf-sheaths without keel; smooth. Ligule an eciliate membrane; 3-6 mm long; obtuse, or acute. Leaf-blades flat, or conduplicate; 2-12 cm long; 2-5 mm wide. Leaf-blade surface smooth; glabrous. Leaf-blade margins smooth, or scaberulous. Leaf-blade apex obtuse, or abruptly acute; hooded.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; ovate; dense, or loose; equilateral, or nodding; 3-7 cm long; 3-7 cm wide. Primary panicle branches spreading; 2 -nate. Panicle branches scaberulous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels 0.5-2 mm long.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2-5 fertile florets; with diminished florets at the apex. Spikelets oblong, or ovate; laterally compressed; 4-7 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite; obscured by lemmas; smooth. Floret callus pubescent.
Fertile
Spikelets comprising 2-5 fertile florets; with diminished florets at the apex. Spikelets oblong, or ovate; laterally compressed; 4-7 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite; obscured by lemmas; smooth. Floret callus pubescent.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; shorter than spikelet. Lower glume elliptic, or ovate; 2.5-4 mm long; 0.8-0.9 length of upper glume; membranous; much thinner on margins; 1-keeled; 1-3 -veined. Lower glume primary vein scabrous. Lower glume apex acute. Upper glume elliptic, or ovate; 3-4.5 mm long; 0.8-0.9 length of adjacent fertile lemma; membranous; with hyaline margins; 1-keeled; 3 -veined. Upper glume primary vein scabrous. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Fertile lemma ovate; oblong in profile; 3.5-5 mm long; membranous; much thinner above; keeled; 5 -veined. Lemma midvein ciliate; hairy below. Lemma lateral veins stopping well short of apex. Lemma surface pubescent; hairy on veins. Lemma margins ciliate; hairy below. Lemma apex acute. Palea 1 length of lemma. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Lodicules 2; membranous. Anthers 3; 1.5-2.5 mm long.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp. Hilum punctiform.
