Morphology General Habit
Annual; caespitose. Culms erect, or geniculately ascending; 10-120 cm long. Ligule a fringe of hairs. Leaf-blades 3-30 cm long; 2-10 mm wide.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Racemes 3-10; borne along a central axis; unilateral; 1-5 cm long. Central inflorescence axis 3-20 cm long. Rhachis wingless, or narrowly winged; angular; puberulous on surface. Spikelet packing adaxial; regular; 2 -rowed. Spikelets ascending; solitary. Fertile spikelets pedicelled. Pedicels oblong; setose.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; acuminate; (2.5-)3-5 mm long; falling entire. Spikelet callus globular; incorporating lowest rhachilla internode with adnate lower glume; glabrous.
Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; acuminate; (2.5-)3-5 mm long; falling entire. Spikelet callus globular; incorporating lowest rhachilla internode with adnate lower glume; glabrous.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes one the lower absent or obscure; exceeding apex of florets; thinner than fertile lemma. Upper glume elliptic; (2.5-)3-5 mm long; 1 length of spikelet; membranous; without keels; 5 -veined. Upper glume surface pubescent. Upper glume apex attenuate; awned; 1 -awned. Upper glume awn 0.5-4 mm long.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets barren; without significant palea. Lemma of lower sterile floret similar to upper glume; elliptic; 0.9 length of spikelet; 5 -veined; pubescent; attenuate; awned. Awn of lower sterile floret 0.2-3 mm long. Fertile lemma elliptic; 2-3 mm long; indurate; without keel; 5 -veined. Lemma surface punctate. Lemma margins involute. Lemma apex obtuse; mucronate. Principal lemma awn 0.3-1 mm long overall. Palea involute; indurate.
