Description.

Perennial herb from a woody taproot and base with stems to 40 cm, plant roughly tomentose with longish white hairs. Basal leaves 5-11 × 0.6-1.7 cm, oblanceolate, obtuse or rounded, margin entire to slightly undulate, base narrowed into a pseudopetiole c. 2-4 cm long; stem leaves and bracts sessile, 2-5 × 1.5-2 cm, ovate, acute, base broadly cuneate. Flowers in many-flowered, axillary, pedunculate heads, mostly 2-2.5 cm in diameter, occasionally somewhat elongate; peduncles 1.5-5 cm; bracteoles 10-15 × 1-3 mm, linear to lanceolate, long acuminate, pilose; pedicels absent; sepals 8-9 × 2.5-3 mm, lanceolate, acuminate, long-pilose, inner sepals slightly narrower, c. 2 mm wide; corolla 2-2.3 cm long, pink, midpetaline bands pilose, very shallowly lobed with midpetaline bands terminating in a comose point; ovary glabrous; style glabrous, divided 5 mm above base, stigmas 4 mm. Capsule glabrous; seeds glabrous. [ Sa’ad 1967: 157; Rechinger 1961: 24]

Distribution.

Iran, Iraq (Barklay & Palmatier 2266; Rechinger 9797, 9959; Alizzi & Husain 34096; Rawi & Nur 27028; Hamad 48878); Saudi Arabia? Common in Iraq but very rare or absent elsewhere.

Notes.

Resembles Convolvulus cephalopodus subsp. bushiricus very closely in overall morphology but the heads are larger, pedunculate almost to the apex of the stem, the bracteoles are much longer and the ovary and style are glabrous.
