Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Racemes 1; single; linear; bilateral; 5-8 cm long; bearing 12-16 fertile spikelets on each. Rhachis fragile at the nodes. Spikelet packing broadside to rhachis. Rhachis internodes oblong; 0.5 length of fertile spikelet; falling with spikelet above. Spikelets solitary. Fertile spikelets sessile.
Morphology Reproductive morphology Inflorescences Spikelets
Basal sterile spikelets rudimentary; 1 in number. Spikelets comprising 1-2 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 5.5-8.5 mm long; falling entire; deciduous with accessory branch structures.
Sterile
Basal sterile spikelets rudimentary; 1 in number.
Fertile
Spikelets comprising 1-2 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 5.5-8.5 mm long; falling entire; deciduous with accessory branch structures.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes similar; shorter than spikelet. Lower glume oblong; 5-7 mm long; 1 length of upper glume; coriaceous; without keels; 4-6 -veined. Lower glume lateral veins distinct; ribbed. Lower glume apex with a unilateral tooth, or dentate; 1-2 -fid. Upper glume oblong; 5-7 mm long; 1.2 length of adjacent fertile lemma; coriaceous; without keels; 4-6 -veined. Upper glume lateral veins distinct; ribbed; parallel at apex. Upper glume apex with a unilateral tooth, or dentate; 1-2 -fid.
Morphology Reproductive morphology Flowers Florets
Fertile lemma elliptic; 4-6 mm long; coriaceous; keeled; keeled above; 5 -veined. Lemma apex entire; awned; 1 -awned. Principal lemma awn 30-60 mm long overall. Palea 2 -veined. Palea keels scaberulous. Apical sterile florets resembling fertile though underdeveloped.
