Morphology General Habit
Annual, or perennial; short-lived. Culms geniculately ascending; 10-40 cm long. Ligule a fringe of hairs. Leaf-blades flat; 2-20 cm long; 2-5 mm wide.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle spiciform; linear to oblong; 2-6 cm long. Primary panicle branches accrescent to a central axis; with sessile scars on axis. Panicle axis angular; scaberulous; bearing deciduous spikelet clusters. Spikelets subtended by an involucre. Fertile spikelets sessile; 1-3 in the cluster. Involucre composed of bristles; connate into a cup below; with 1-2.5 mm connate; 6-12 mm long; base obconical. Involucral bristles deciduous with the fertile spikelets; numerous; with an outer whorl of thinner bristles; inner bristles longer than outer; with one conspicuously longer bristle; 8-16 mm long; flattened; without grooves, or grooved on the face; flexible (often wavy); antrorsely scaberulous; glabrous, or ciliate.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate, or ovate; dorsally compressed; acute; 3-5 mm long; falling entire; deciduous with accessory branch structures.
Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate, or ovate; dorsally compressed; acute; 3-5 mm long; falling entire; deciduous with accessory branch structures.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes one the lower absent or obscure, or two; similar; shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate, or ovate; 2-3 mm long; 0.5-0.66 length of spikelet; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume surface puberulous. Lower glume apex obtuse, or acute. Upper glume lanceolate, or ovate; 2-3.5 mm long; 0.66 length of spikelet; membranous; without keels; 1-3 -veined. Upper glume surface puberulous. Upper glume apex obtuse, or acute.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets male, or barren; with palea. Lemma of lower sterile floret oblong; 1 length of fertile lemma; membranous; 5 -veined; puberulous; obtuse, or acute. Fertile lemma elliptic; dorsally compressed; 3-5 mm long; chartaceous; without keel; 5 -veined. Lemma surface asperulous. Lemma margins covering most of palea. Lemma apex acute; mucronate. Palea 1 length of lemma; chartaceous; 2 -veined.
Morphology Reproductive morphology Flowers
Anthers 3; 3 mm long.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp; obovoid; dorsally compressed; 1.5-2 mm long; truncate.
