Leymus golmudensis

HABIT Perennial; caespitose. Rhizomes elongated. Culms erect; 30–70 cm long. Ligule an eciliate membrane. Leaf-blades filiform; involute; 1–2 mm wide; coriaceous; stiff.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 1; single; linear; bilateral; 4.5–14 cm long. Spikelet packing broadside to rhachis; lax. Rhachis internodes linear.

Spikelets solitary. Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 3–4 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 8–10 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume linear; 5–7 mm long; 0.75 length of upper glume; coriaceous; 0–1 -veined. Lower glume lateral veins absent. Lower glume apex acuminate. Upper glume linear; 7–9 mm long; 1 length of adjacent fertile lemma; coriaceous; without keels; 0–1 -veined. Upper glume apex acuminate.

FLORETS Fertile lemma lanceolate, or oblong; 7–8 mm long; coriaceous; without keel; 5 -veined. Lemma surface glabrous. Lemma apex acuminate; mucronate. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Anthers 3; 2.5–3 mm long.
