Alopecurus creticus

HABIT Annual; caespitose. Culms geniculately ascending; 7–22 cm long; 2–3 -noded; rooting from lower nodes. Culm-internodes distally glabrous. Lateral branches sparse. Leaf-sheaths glabrous on surface. Ligule an eciliate membrane; 2–3 mm long; obtuse. Leaf-blades 1–7 cm long; 1–3.5 mm wide. Leaf-blade surface glabrous. Leaf-blade apex acuminate.

INFLORESCENCE Inflorescence a panicle; subtended by an unspecialized leaf-sheath, or an inflated leaf-sheath.

Panicle spiciform; linear; 2–3.5 cm long; 0.4–0.5 cm wide. Primary panicle branches accrescent to a central axis; with evident branchlets on axis. Panicle axis with rounded ribs.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels oblong.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; 3–4 mm long; falling entire.

GLUMES Glumes connate along margins below; 0.5–0.8 of their length connate; similar; exceeding apex of florets; recurved at apex. Lower glume lanceolate; 3–4 mm long; 1 length of upper glume; membranous; 1-keeled; winged on keel; 3 -veined. Lower glume primary vein ciliate. Lower glume surface pilose; hairy above. Lower glume apex obtuse; mucronate. Upper glume lanceolate; 3–4 mm long; 1.1 length of adjacent fertile lemma; membranous; 1-keeled; winged on keel; 3 -veined. Upper glume primary vein ciliate. Upper glume surface pilose; hairy above. Upper glume apex obtuse; mucronate.

FLORETS Fertile lemma oblong; 2.7–3.5 mm long; membranous; keeled; 5 -veined. Lemma margins connate below; with 0.5–0.66 of their length connate. Lemma apex truncate; awned; 1 -awned. Principal lemma awn dorsal; arising 0.5 way up back of lemma; geniculate; 3–6 mm long overall; with twisted column. Palea absent or minute.

FLOWER Lodicules absent. Anthers 3; 1.2–2.5 mm long. Stigmas terminally exserted; pubescent. Ovary glabrous.

FRUIT Caryopsis with adherent pericarp. Hilum punctiform. Disseminule comprising a spikelet.

DISTRIBUTION Europe: southeastern. Asia-temperate: western Asia.
