Puccinellia candida
HABIT Perennial; caespitose; clumped loosely. Culms erect, or geniculately ascending; 40–90 cm long. Ligule an eciliate membrane; 1 mm long; obtuse. Leaf-blades convolute. Leaf-blade surface scabrous; rough adaxially.
INFLORESCENCE Inflorescence a panicle.
Panicle open; ovate, or pyramidal; (10–)15–35 cm long. Primary panicle branches ascending, or spreading; 10–15 cm long.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising (3–)4–6 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 4–7 mm long; breaking up at maturity; disarticulating below each fertile floret.
GLUMES Glumes persistent; shorter than spikelet. Lower glume ovate; 1–2.5 mm long; 0.4–0.8 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume margins ciliate. Lower glume apex acute. Upper glume lanceolate; (1.75–)2.5–3 mm long; 1 length of adjacent fertile lemma; membranous; without keels; 3 -veined. Upper glume margins ciliate. Upper glume apex acute.
FLORETS Fertile lemma oblong; 2.5–3 mm long; membranous; keeled; 5 -veined. Lemma lateral veins distinct; stopping well short of apex. Lemma surface puberulous; hairy below; hairy on veins. Lemma margins ciliolate. Lemma apex obtuse. Palea 2 -veined. Palea keels ciliate. Apical sterile florets resembling fertile though underdeveloped.
FLOWER Anthers 3; 1.5–1.75 mm long.
DISTRIBUTION Asia-temperate: Siberia.
