INFLORESCENCE Inflorescence composed of racemes; deciduous as a whole.

Racemes 1; single; lanceolate; bilateral; 1–1.5 cm long; bearing few fertile spikelets; bearing 3 fertile spikelets on each. Rhachis tough. Spikelet packing broadside to rhachis.

Spikelets solitary. Fertile spikelets sessile.

STERILE SPIKELETS Basal sterile spikelets rudimentary; (2–)3 in number.

FERTILE SPIKELETS Spikelets comprising 3–4 fertile florets; with diminished florets at the apex. Spikelets elliptic, or ovate; laterally compressed; 13–15 mm long; falling entire; deciduous with accessory branch structures.

GLUMES Glumes similar; shorter than spikelet. Lower glume oblong; gibbous; 9–11 mm long; 1 length of upper glume; coriaceous; without keels; 7–9 -veined. Lower glume lateral veins thickened; ribbed. Lower glume apex dentate; 2 -fid; awned; 1 -awned. Lower glume awn 30–50 mm long. Upper glume oblong; gibbous; 9–11 mm long; 0.9 length of adjacent fertile lemma; coriaceous; without keels; 7–9 -veined. Upper glume lateral veins thickened; ribbed; parallel at apex. Upper glume apex dentate; 2 -fid; awned; 1 -awned. Upper glume awn 30–40 mm long.

FLORETS Fertile lemma oblong; 9–11 mm long; coriaceous; without keel; 5 -veined. Lemma apex dentate; 2 -fid; awned; 1 -awned. Principal lemma awn 3 mm long overall. Palea 2 -veined. Palea keels scaberulous. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Lodicules 2. Ovary pubescent on apex.

FRUIT Caryopsis with adherent pericarp; hairy at apex. Disseminule comprising a inflorescence.

DISTRIBUTION Europe: southeastern. Asia-temperate: western Asia.
