Poa sublanata

HABIT Perennial. Rhizomes elongated. Culms 50–70 cm long. Lateral branches lacking. Leaf-sheaths glabrous on surface. Ligule an eciliate membrane; 5 mm long; lacerate; acuminate. Leaf-blades flat, or conduplicate; 20–30 cm long; 3–3.5 mm wide.

INFLORESCENCE Inflorescence a panicle.

Panicle open; pyramidal; 12–17 cm long; 7–8 cm wide. Primary panicle branches 3–6 -nate; 1–8 cm long; bearing 1–3 fertile spikelets on each lower branch. Panicle branches smooth.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 4–5 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 6–8 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus woolly.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; membranous; 1-keeled; 3 -veined. Lower glume apex acute. Upper glume ovate; membranous; 1-keeled; 3 -veined. Upper glume apex acute.

FLORETS Fertile lemma ovate; 4–4.5 mm long; membranous; keeled; 5 -veined. Lemma midvein ciliate; hairy below. Lemma lateral veins prominent. Lemma surface puberulous. Lemma margins ciliate; hairy below. Lemma apex acute. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Lodicules 2; membranous. Anthers 3.

FRUIT Caryopsis with adherent pericarp. Hilum punctiform.

DISTRIBUTION Asia-temperate: Siberia and Soviet far east.
