Colpodium colchicum

HABIT Perennial; caespitose. Rhizomes elongated. Culms 15–70 cm long. Ligule an eciliate membrane; 3–7 mm long; erose; obtuse, or acute. Leaf-blades 2–5 cm long; 2–6 mm wide. Leaf-blade surface glabrous.

INFLORESCENCE Inflorescence a panicle.

Panicle open; elliptic; nodding; 2–10 cm long; 1.5–3 cm wide.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets cuneate; laterally compressed; 4.5–5.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus glabrous.

GLUMES Glumes persistent; similar; reaching apex of florets; similar to fertile lemma in texture; gaping. Lower glume lanceolate; 3–4.5 mm long; 0.75–0.9 length of upper glume; membranous; much thinner above; much thinner on margins; 1-keeled; keeled below; 1 -veined. Lower glume lateral veins absent. Lower glume apex obtuse, or acute. Upper glume lanceolate; 4.2–5 mm long; 1 length of adjacent fertile lemma; membranous; much thinner above; with hyaline margins; 1-keeled; keeled below; 3 -veined. Upper glume lateral veins all falling short of apex. Upper glume apex obtuse, or acute.

FLORETS Fertile lemma oblong, or obovate; 4.5–5.5 mm long; membranous; much thinner above; keeled. Lemma lateral veins less than two thirds length of lemma. Lemma surface pilose; hairy below; hairy on veins. Lemma apex erose; obtuse. Palea keels smooth; eciliate.

FLOWER Anthers 3; 3 mm long; purple.

FRUIT Hilum elliptic.

DISTRIBUTION Asia-temperate: Caucasus and western Asia.
