INFLORESCENCE Inflorescence composed of racemes.

Racemes 1; single; erect; straight, or arcuate; smoothly terete; bilateral; 6–16 cm long. Rhachis fragile at the nodes; semiterete; 1.5–4 mm wide; glabrous on surface, or puberulous on surface; smooth on margins. Spikelet packing broadside to rhachis. Rhachis internodes oblong; 6–10 mm long. Rhachis internode tip transverse.

Spikelets appressed; solitary. Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 1–2 fertile florets; with a barren rhachilla extension. Spikelets oblong; dorsally compressed; 7–10 mm long; falling entire; deciduous with accessory branch structures.

GLUMES Glumes collateral; similar; with lower wider than upper; exceeding apex of florets; firmer than fertile lemma. Lower glume oblong; 1 length of upper glume; coriaceous; without keels; 7–9 -veined. Lower glume surface glabrous, or puberulous. Lower glume apex obtuse. Upper glume oblong; coriaceous; without keels; 5–7 -veined. Upper glume surface glabrous, or puberulous. Upper glume apex acute.

FLORETS Fertile florets appressed to rhachilla. Fertile lemma oblong; 7–8 mm long; membranous; without keel; 3–5 -veined. Lemma surface puberulous; hairy below; with clavate hairs. Lemma apex acute. Palea surface pubescent. Rhachilla extension 0.2 length of fertile floret; pubescent.

FLOWER Lodicules 2; ovate; 1.3–1.8 mm long; membranous; ciliate; hairy across the apex. Anthers 3; 1.5–2.2 mm long. Ovary pubescent on apex.

FRUIT Caryopsis with adherent pericarp; oblong; dorsally compressed; sulcate on hilar side; 6–7 mm long; dark brown; hairy at apex. Embryo 0.3 length of caryopsis. Hilum linear; 1 length of caryopsis.

DISTRIBUTION Asia-temperate: Soviet Middle Asia, Caucasus, and western Asia. Asia-tropical: India.
