Elymus habahenensis

HABIT Perennial; caespitose; clumped loosely. Rhizomes short. Culms erect; 80–120 cm long. Leaf-sheaths pilose. Ligule an eciliate membrane; lacerate. Leaf-blade margins ciliate.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 1; single; bilateral; 3–8 cm long; 5–10 mm wide. Rhachis flattened; pubescent on surface. Spikelet packing broadside to rhachis; crowded.

Spikelets pectinate; solitary. Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 3–11 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 15 mm long; 2 mm wide; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; similar. Lower glume lanceolate; asymmetrical; 3–7 mm long; coriaceous; 1-keeled; 3–5 -veined. Lower glume primary vein ciliate. Lower glume apex acute, or acuminate. Upper glume lanceolate; asymmetrical; 3–7 mm long; coriaceous; 1-keeled; 3–5 -veined. Upper glume primary vein ciliate. Upper glume apex acute, or acuminate.

FLORETS Fertile lemma lanceolate; 7 mm long; coriaceous; 5 -veined. Lemma surface pubescent. Lemma apex acuminate; awned; 1 -awned. Principal lemma awn 3 mm long overall. Palea 1 length of lemma; 2 -veined. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Lodicules 2; ciliate. Anthers 3; 2 mm long.

FRUIT Caryopsis with adherent pericarp.

DISTRIBUTION Asia-temperate: China.
