Anthoxanthum pluriflorum

HABIT Perennial; culms solitary. Rhizomes elongated. Culms 18–40 cm long; 1–1.2 mm diam. Ligule a ciliolate membrane. Leaf-blades involute; 25–40 cm long; 4–6 mm wide.

INFLORESCENCE Inflorescence a panicle.

Panicle open; oblong; 2–3 cm long; 1–1.5 cm wide.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; laterally compressed; 5–6 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; similar; reaching apex of florets; thinner than fertile lemma; shiny. Lower glume ovate; 5–6 mm long; 1 length of upper glume; membranous; 1-keeled; 3 -veined. Lower glume apex obtuse. Upper glume ovate; 5–6 mm long; 1.2 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume apex obtuse.

FLORETS Basal sterile florets similar; male; with palea; attached to and deciduous with the fertile. Lemma of lower sterile floret elliptic; 4.5–5.5 mm long; 1 length of fertile lemma; chartaceous; 1-keeled; 5 -veined; pubescent; ciliate on margins; obtuse; muticous, or mucronate. Awn of lower sterile floret 0–2 mm long. Lemma of upper sterile floret oblong; 4.5–5.5 mm long; chartaceous; pubescent; ciliate on margins; muticous. Fertile lemma ovate; 4–5 mm long; cartilaginous; without keel. Lemma surface pubescent; hairy at base. Lemma margins convolute; covering most of palea. Lemma apex acute. Palea elliptic; 1 -veined; without keels.

FLOWER Anthers 2 (bisexual), or 3 (male). Ovary glabrous.

FRUIT Caryopsis with adherent pericarp.

DISTRIBUTION Asia-temperate: eastern Asia.
