Glyceria striata

HABIT Perennial; caespitose. Rhizomes absent, or short. Culms erect; 40–90 cm long. Leaf-sheaths tubular for much of their length; with 1 of their length closed; without keel; smooth; glabrous on surface. Ligule an eciliate membrane; 1.5–4 mm long. Leaf-blades flat, or conduplicate; 2–8 mm wide. Leaf-blade surface smooth; glabrous.

INFLORESCENCE Inflorescence a panicle.

Panicle open; ovate; nodding; 12–22 cm long. Primary panicle branches drooping; 6–12 cm long. Panicle branches flexuous; smooth, or scaberulous.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 3–7 fertile florets; with diminished florets at the apex. Spikelets oblong, or ovate; laterally compressed; 3–4 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume ovate; 0.4–0.9 mm long; 0.9 length of upper glume; membranous; much thinner on margins; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume surface puberulous; hairy at apex. Lower glume apex obtuse. Upper glume ovate; 0.5–1 mm long; 0.33–0.5 length of adjacent fertile lemma; membranous; with hyaline margins; without keels; 1 -veined. Upper glume surface puberulous; hairy at apex. Upper glume apex obtuse.

FLORETS Fertile lemma obovate; 1.5–2 mm long; membranous; without keel; 7 -veined. Lemma lateral veins prominent. Lemma apex erose; obtuse. Palea bowed outwards; 1 length of lemma; 2 -veined. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Lodicules 2; united; oblong; fleshy; truncate. Anthers 2; 0.3–0.5 mm long.

FRUIT Caryopsis with adherent pericarp. Hilum linear.

DISTRIBUTION Europe: central, southwestern, and eastern. Australasia: New Zealand. North America: Subarctic, western Canada, eastern Canada, northwest USA, north-central USA, northeast USA, southwest USA, south-central USA, southeast USA, and Mexico. South America: Mesoamericana.
