Puccinellia schischkinii

HABIT Perennial; caespitose; clumped moderately, or densely. Basal innovations intravaginal. Culms erect, or geniculately ascending; 20–55 cm long. Leaf-sheaths open for most of their length; smooth. Ligule an eciliate membrane; 2–3 mm long; obtuse, or acute. Leaf-blades flat, or convolute; 1–3 mm wide; stiff; grey-green. Leaf-blade surface scaberulous; rough adaxially.

INFLORESCENCE Inflorescence a panicle.

Panicle open; linear; 8–27 cm long. Primary panicle branches appressed; 4–9 cm long; naked below, or bearing spikelets almost to the base. Panicle branches scabrous.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 3–7 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; compressed slightly; 5–10 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; shorter than spikelet. Lower glume linear; 0.9–1.5 mm long; 0.5–0.6 length of upper glume; membranous; without keels; keel-less except near apex; 1 -veined. Lower glume lateral veins absent. Lower glume margins ciliolate. Lower glume apex erose; acute. Upper glume linear; 1.6–2.6 mm long; 0.75 length of adjacent fertile lemma; membranous; without keels; keel-less except near apex; 3 -veined. Upper glume margins ciliolate. Upper glume apex erose; obtuse.

FLORETS Fertile lemma ovate; 2.2–3.2 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 margins ciliolate; hairy above. Lemma apex erose; obtuse. Palea 2 -veined. Palea keels scabrous. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Anthers 3; 0.7–1.2 mm long. Ovary glabrous.

FRUIT Caryopsis with adherent pericarp; 1.6–1.8 mm long. Hilum punctiform.

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