Puccinellia manchuriensis

HABIT Perennial; caespitose; clumped loosely. Cataphylls inconspicuous. Culms 30–50 cm long; 1–2 mm diam. Leaf-sheaths open for most of their length. Ligule an eciliate membrane; 1–2 mm long. Leaf-blades flat, or convolute; 1.2–3 mm wide. Leaf-blade surface scaberulous.

INFLORESCENCE Inflorescence a panicle.

Panicle open; elliptic; 10–25 cm long. Primary panicle branches 7–13 cm long. Panicle branches scabrous.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 4–5 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; compressed slightly; 4–5 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; shorter than spikelet. Lower glume ovate; 1 mm long; 0.75 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex obtuse. Upper glume ovate; 1.5 mm long; 1 length of adjacent fertile lemma; membranous; without keels; 3 -veined. Upper glume apex obtuse.

FLORETS Fertile lemma oblong; 1.5 mm long; membranous; much thinner above; without keel; 5 -veined. Lemma lateral veins obscure; stopping well short of apex. Lemma surface pubescent; hairy at base. Lemma apex obtuse. Palea 2 -veined. Palea keels scabrous; ciliolate. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Anthers 3; 1–1.3 mm long. Ovary glabrous.

FRUIT Caryopsis with adherent pericarp. Hilum punctiform.

DISTRIBUTION Asia-temperate: Siberia, Soviet far east, China, and Mongolia.
