Koeleria eriostachya

HABIT Perennial; caespitose. Rhizomes short. Butt sheaths pubescent; withering, or persistent and investing base of culm; with compacted dead sheaths. Culms erect; 15–20 cm long; 1–2 -noded. Lateral branches lacking. Leaves mostly basal. Leaf-sheaths glabrous on surface. Ligule an eciliate membrane; 0.5–1 mm long; truncate. Leaf-blades convolute; 5–20 cm long; 1–3 mm wide. Leaf-blade surface pubescent. Leaf-blade apex acuminate.

INFLORESCENCE Inflorescence a panicle. Peduncle glabrous, or pubescent above.

Panicle spiciform; oblong; continuous, or interrupted; 2–8 cm long; 0.6–1.5 cm wide. Panicle axis pubescent. Panicle branches pubescent.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels pubescent.

FERTILE SPIKELETS Spikelets comprising 2–3 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 4.5–6.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pubescent.

GLUMES Glumes persistent; similar; shorter than spikelet; similar to fertile lemma in texture; shiny; gaping. Lower glume lanceolate; 2.9–4.8 mm long; 0.75–1 length of upper glume; membranous; much thinner on margins; mid-green, or purple; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume surface pubescent. Lower glume apex acuminate. Upper glume lanceolate; 3.5–5.2 mm long; 0.9–1 length of adjacent fertile lemma; membranous; with hyaline margins; mid-green, or purple; 1-keeled; 3 -veined. Upper glume surface pubescent. Upper glume apex acuminate.

FLORETS Fertile lemma oblong; 3.8–5.8 mm long; membranous; much thinner on margins; shiny; keeled; 5 -veined. Lemma surface pubescent. Lemma apex acuminate. Palea gaping; 1 length of lemma. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Lodicules 2; membranous. Anthers 3; 2.5–4 mm long. Ovary glabrous.

DISTRIBUTION Europe: central and southeastern. Asia-temperate: Caucasus and western Asia.

NOTES Aveneae. Fl Turk 1993.
