    [GB]
    Habit
    Perennial; caespitose. Culms erect; 2-12 cm long. Leaf-sheaths open for most of their length; glabrous on surface. Ligule an eciliate membrane; 0.5-1 mm long. Leaf-blades flat, or convolute; 1-7 cm long; 1 mm wide. Leaf-blade surface glabrous. Leaf-blade margins ciliate. Leaf-blade apex obtuse; hooded.
    Inflorescences
    Inflorescence a panicle. Peduncle tipped by a glumaceous appendage (treated as sterile spikelets). Panicle capitate; globose; 0.5-0.7 cm long; 0.5-0.7 cm wide. Primary panicle branches accrescent to a central axis; with evident branchlets on axis, or with lateral stumps on axis. Spikelets solitary. Fertile spikelets pedicelled. Pedicels oblong; 1-1.5 mm long.
    Spikelets
    Basal sterile spikelets represented by a single scale; 2 in number; orbicular. Basal sterile spikelet glumes membranous. Spikelets comprising 4 fertile florets; with a barren rhachilla extension. Spikelets oblong; laterally compressed; 4.5 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Sterile
    Basal sterile spikelets represented by a single scale; 2 in number; orbicular. Basal sterile spikelet glumes membranous.
    Fertile
    Spikelets comprising 4 fertile florets; with a barren rhachilla extension. Spikelets oblong; laterally compressed; 4.5 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume ovate; 4 mm long; 1 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume margins ciliolate. Lower glume apex acute; awned; 1 -awned. Lower glume awn 1.5 mm long. Upper glume ovate; 4 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume margins ciliolate. Upper glume apex acute; awned; 1 -awned. Upper glume awn 1.5 mm long.
    Florets
    Fertile lemma ovate; 3.5-4 mm long; membranous; grey; without keel; 3-5 -veined. Lemma surface pilose; hairy below. Lemma margins ciliate. Lemma apex dentate; 3 -fid; awned; 1 -awned. Principal lemma awn 0.5-1 mm long overall. Palea 1 length of lemma; 2 -veined. Palea keels ciliolate.
    Flowers
    Anthers 3; 1.8 mm long. Stigmas 2; terminally exserted; pubescent. Ovary glabrous.
    Fruits
    Caryopsis with adherent pericarp; 1.5 mm long; glabrous. Hilum elliptic.
    Distribution
    Europe: central and southeastern.
