Phleum crypsoides

HABIT Annual; caespitose. Culms erect; (1–)2–2.5(–4) cm long. Leaf-sheaths glabrous on surface. Ligule an eciliate membrane; 1–2 mm long. Leaf-blades 0.4–2.5 cm long; 1–2.5 mm wide. Leaf-blade surface scaberulous; rough adaxially. Leaf-blade margins scaberulous.

INFLORESCENCE Inflorescence a panicle; shorter than basal leaves; subtended by an inflated leaf-sheath; embraced at base by subtending leaf.

Panicle spiciform; elliptic, or ovate; 3–5 cm long; 0.4–0.7 cm wide. Primary panicle branches accrescent to a central axis; with evident branchlets on axis.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; with a barren rhachilla extension. Spikelets elliptic, or ovate; laterally compressed; truncate; 3–3.8 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; similar; exceeding apex of florets. Lower glume elliptic; 3–3.8 mm long; 1 length of upper glume; membranous; much thinner on margins; 1-keeled; winged on keel; 3 -veined. Lower glume primary vein spinulose. Lower glume surface pubescent. Lower glume apex truncate; mucronate. Upper glume elliptic; 3–3.8 mm long; 3–4 length of adjacent fertile lemma; membranous; with hyaline margins; 1-keeled; wingless; 3 -veined. Upper glume primary vein spinulose. Upper glume surface pubescent. Upper glume apex truncate; mucronate (0.2–0.3mm).

FLORETS Fertile lemma ovate; 0.8–1 mm long; membranous; without keel; 1 -veined. Lemma surface glabrous. Lemma apex obtuse. Palea 0.6–0.7 length of lemma.

FLOWER Lodicules 2; membranous. Anthers 2; 0.7–0.9 mm long. Ovary glabrous.

FRUIT Caryopsis with adherent pericarp; ovoid; isodiametric; 0.9–1 mm long. Hilum punctiform.

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

NOTES Aveneae. Fl Turk.
