Morphology General Habit
Annual; culms solitary. Culms erect, or prostrate; 1-30 cm long. Lateral branches lacking, or sparse. Leaf-sheaths inflated; longer than adjacent culm internode; without keel; ribbed; smooth; glabrous on surface, or pilose; with tubercle-based hairs; outer margin glabrous, or hairy. Ligule a fringe of hairs. Leaf-blades flat, or involute; 0.5-2 cm long; 1-5 mm wide; stiff; glaucous. Leaf-blade surface ribbed; scabrous; rough adaxially; pilose; sparsely hairy; hairy on both sides; with tubercle-based hairs. Leaf-blade margins scabrous. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle; comprising 8-15 fertile spikelets; subtended by an inflated leaf-sheath; embraced at base by subtending leaf, or enclosed. Panicle capitate; elliptic, or ovate; 0.5-1 cm long; 0.4-0.5 cm wide. Panicle axis glabrous. Spikelets solitary, or in pairs. Fertile spikelets sessile, or sessile and pedicelled.
Sterile
Basal sterile spikelets well-developed; 1-2 in number.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets cuneate; laterally compressed; 3-4 mm long; falling entire. Basal sterile spikelets well-developed; 1-2 in number.
Fertile
Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets cuneate; laterally compressed; 3-4 mm long; falling entire.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes similar; with lower narrower than upper; shorter than spikelet. Lower glume lanceolate; 2-2.5 mm long; 0.9 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein scabrous; eciliate. Lower glume lateral veins absent. Lower glume margins eciliate. Lower glume apex caudate. Upper glume lanceolate, or ovate; 2-2.5 mm long; 0.9 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume primary vein scabrous. Upper glume lateral veins absent. Upper glume margins eciliate. Upper glume apex caudate.
Morphology Reproductive morphology Flowers Florets
Fertile lemma lanceolate; 2-2.5 mm long; membranous; keeled; 1 -veined. Lemma apex caudate. Palea 1.2-2 mm long; 2 -veined. Palea apex dentate; 4 -fid.
Morphology Reproductive morphology Flowers
Lodicules absent. Anthers 3; 2.5 mm long; yellow, or brown.
Morphology Reproductive morphology Fruits
Caryopsis ellipsoid, or oblong; 1.5-2 mm long. Embryo 0.75 length of caryopsis.
