    Habit
    Compactly tufted perennial from a tough branching rhizome.
    Culms
    Culms 20–70 cm. high, moderately slender, ascending, branched only at the lowest node.
    Leaves
    Leaf-blades usually folded, 8–55 cm. long, 2.5–5 mm. wide, tufts of soft white hairs scattered along the smooth or inconspicuously scaberulous margins, tip subacute; ligule 0.3–0.5 mm. long, a ciliolate membrane.
    Inflorescences
    Inflorescence subdigitate, composed of 2–10 spikes clustered at the culm-apex, 1 or 2 often set below the rest; spikes 2.5–12 cm. long, slender, ascending or spreading.
    Spikelets
    Spikelets 4–7-flowered, elliptic to narrowly elliptic, 3.3–6.8 mm. long; glumes 1-nerved, acute, dark olive-grey, the lower narrowly lanceolate in profile, 1.1–2 mm. long, the upper narrowly elliptic-oblong in profile, 2.6–4.2 mm. long; lemmas narrowly elliptic in profile, 2.8–4.6 mm. long, pale green tinged with grey, lateral nerves indistinct, the tip acute.
    Fruits
    Grain elliptic-oblong to broadly oblong, 0.9–1.4 mm. long, flat on the hilar side, minutely and closely rugulose.
    Habitat
    Naturalized, roadsides; 1800 m.
    Distribution
    K4
    [GB]
    Habit
    Perennial; caespitose. Rhizomes short. Basal innovations flabellate. Culms geniculately ascending; 20-70 cm long. Culm-internodes elliptical in section. Lateral branches lacking (or only at lowest node). Leaf-sheaths keeled. Ligule a ciliolate membrane; 0.3-0.5 mm long. Leaf-blades conduplicate; 8-55 cm long; 2.5-5 mm wide. Leaf-blade margins smooth; with tufts of hair. Leaf-blade apex acute.
    Inflorescences
    Inflorescence composed of racemes. Racemes 2-10; digitate; spreading, or ascending; unilateral; 2.5-12 cm long. Rhachis wingless; flattened. Spikelet packing broadside to rhachis; regular; 2 -rowed. Spikelets appressed; solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 4-7 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 3.3-6.8 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Fertile
    Spikelets comprising 4-7 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 3.3-6.8 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 1.1-2 mm long; 0.4-0.5 length of upper glume; membranous; dark green; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume elliptic; 2.6-4.2 mm long; 0.9 length of adjacent fertile lemma; membranous; dark green; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume apex acute.
    Florets
    Fertile lemma elliptic in profile; 2.8-4.6 mm long; membranous; mid-green and grey; 3 -veined. Lemma midvein simple. Lemma apex acute. Palea 0.9-1 length of lemma; 2 -veined. Palea keels scaberulous. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; cuneate; fleshy.
    Fruits
    Caryopsis with free soft pericarp; ellipsoid, or oblong; trigonous; 0.9-1.4 mm long; black; rugose.
    Distribution
    Europe: northern. Africa: north, northeast tropical, and east tropical. Asia-temperate: Arabia.
