Cutandia memphitica

HABIT Annual. Culms erect, or decumbent; 10–30 cm long. Leaf-sheaths inflated. Ligule an eciliate membrane; 2–5 mm long; lacerate; truncate, or obtuse. Leaf-blades deciduous at the ligule; conduplicate; 3–9 cm long; 1–1.5 mm wide.

INFLORESCENCE Inflorescence a panicle; embraced at base by subtending leaf.

Panicle open; elliptic; 3–18 cm long. Primary panicle branches branching divaricately. Panicle axis bearing deciduous branches. Panicle branches stiff; straight; angular; with prominent pulvini.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels oblong; angular; 0.3–0.6(–1.5) mm long.

FERTILE SPIKELETS Spikelets comprising 3–8 fertile florets; with diminished florets at the apex. Spikelets oblanceolate; laterally compressed; 7–12 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1.5–3.2 mm long; scaberulous.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 3.5–5 mm long; 0.7–0.8 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein smooth, or scaberulous. Lower glume lateral veins absent. Lower glume apex acute, or acuminate; mucronate. Upper glume lanceolate; 4.5–6 mm long; 0.7–0.8 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume primary vein smooth, or scaberulous. Upper glume lateral veins absent. Upper glume apex acute, or acuminate; mucronate.

FLORETS Fertile lemma lanceolate; 6–8.5 mm long; membranous; keeled; 3 -veined. Lemma midvein without distinctive roughness, or scaberulous. Lemma apex entire, or dentate; 2 -fid; emarginate; mucronate, or awned. Principal lemma awn from a sinus; 0.5–1.2 mm long overall. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Lodicules 2; membranous. Anthers 3; 1–2 mm long. Ovary glabrous.

FRUIT Caryopsis with adherent pericarp; linear; trigonous; 3–4 mm long. Embryo 0.1–0.15 length of caryopsis. Hilum punctiform.

DISTRIBUTION Europe: southwestern. Africa: north and Macaronesia. Asia-temperate: Soviet Middle Asia, Caucasus, western Asia, and Arabia. Asia-tropical: India. North America: southwest USA.

NOTES Poeae. Fl Iraq.
