Elymus kaachemicus

HABIT Perennial; caespitose; clumped densely. Culms geniculately ascending; 30–45 cm long. Ligule an eciliate membrane. Leaf-blades 1–2 mm wide; glaucous. Leaf-blade surface smooth, or scaberulous; rough adaxially.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 1; single; straight, or arcuate; bilateral. Rhachis flattened. Spikelet packing broadside to rhachis; lax. Rhachis internodes linear.

Spikelets solitary. Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 3–5 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 12 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 5–7 mm long; 1 length of upper glume; coriaceous; without keels; 3 -veined. Upper glume lanceolate; 5–7 mm long; 0.5–0.66 length of adjacent fertile lemma; coriaceous; without keels; 3 -veined. Upper glume apex acuminate.

FLORETS Fertile lemma lanceolate; 10 mm long; coriaceous; 5 -veined. Lemma surface pilose. Lemma apex acute; awned; 1 -awned. Principal lemma awn 4–5 mm long overall. Apical sterile florets resembling fertile though underdeveloped.
