    [GB]
    Habit
    Perennial; caespitose. Culms 17-28 cm long. Culm-internodes smooth; distally glabrous. Leaf-sheaths smooth, or scaberulous. Ligule an eciliate membrane. Leaf-blades 6-9 cm long. Leaf-blade midrib keeled beneath. Leaf-blade surface ribbed (9-15 ribs); grooved adaxially; scabrous; rough abaxially; pubescent; hairy adaxially (on ribs).
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; straight; bilateral; 8-12 cm long; bearing 5-8 fertile spikelets on each. Rhachis flattened; glabrous on surface; ciliate on margins. Spikelet packing broadside to rhachis. Spikelets solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 14-16 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pubescent.
    Fertile
    Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 14-16 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pubescent.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume oblong; 10 mm long; 1.25 length of upper glume; coriaceous; without keels; 3-5 -veined. Lower glume lateral veins ribbed. Lower glume surface asperulous; rough on veins. Lower glume apex acuminate; muticous, or mucronate. Upper glume oblong; 8 mm long; 1 length of adjacent fertile lemma; coriaceous; without keels; 3-5 -veined. Upper glume lateral veins ribbed. Upper glume surface asperulous; rough on veins. Upper glume apex acuminate; mucronate.
    Florets
    Fertile lemma lanceolate to oblong; 8-9 mm long; coriaceous; yellow and purple; bordered with last colour and tipped with last colour; 5 -veined. Lemma surface papillose; glabrous, or puberulous; hairy at base. Lemma apex acute; awned; 1 -awned. Principal lemma awn 9-15 mm long overall. Palea 1 length of lemma. Palea keels scaberulous; ciliolate. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Anthers 3; 2-3 mm long. Stigmas 2. Ovary pubescent on apex.
    Fruits
    Caryopsis with adherent pericarp.
    Distribution
    Asia-temperate: Soviet far east.
