Elymus dshinalicus

HABIT Perennial; caespitose; clumped densely. Rhizomes short. Culms geniculately ascending; 60–65 cm long. Ligule an eciliate membrane. Leaf-blades convolute; 1.5–2.2 mm wide; grey-green. Leaf-blade surface scabrous; rough adaxially; glabrous.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 1; single; straight, or arcuate; bilateral; 15–18 cm long. Rhachis flattened; scabrous on margins. Spikelet packing broadside to rhachis. Rhachis internodes linear. Rhachis internode tip flat.

Spikelets appressed; solitary. Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 5–9 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 12–19 mm long; 4–6 mm wide; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes collateral; persistent; similar; shorter than spikelet. Lower glume lanceolate; 9–10 mm long; 1 length of upper glume; coriaceous; without keels; 5–7 -veined. Lower glume surface scabrous; rough below. Lower glume apex acute. Upper glume lanceolate; 9–10 mm long; coriaceous; without keels; 5–7 -veined. Upper glume surface scabrous; rough below. Upper glume apex acute.

FLORETS Fertile lemma elliptic; 7–9 mm long; coriaceous; 5 -veined. Lemma surface scaberulous; rough above. Lemma apex awned; 1 -awned. Principal lemma awn curved; 17–20 mm long overall. Palea 1 length of lemma. Palea keels scabrous; adorned above; with 0.75 of their length adorned. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Lodicules 2; membranous. Anthers 3. Stigmas 2. Ovary pubescent on apex.

FRUIT Caryopsis with adherent pericarp.

DISTRIBUTION Asia-temperate: Caucasus.
