Description.

Woody based perennial with thick woody taproot, usually branched at base, sometimes more or less cushion-forming, with several erect stems in a loose tuft to c. 40 cm in height, stems and all vegetative parts densely appressed pilose. Basal leaves 3-5 × 0.4-0.8 cm, oblanceolate to spathulate, acute, entire, attenuate at base; stem leaves sessile, 1.5-4.5 × 0.2-0.8 cm, oblong-lanceolate, acute, entire, base cuneate to attenuate. Inflorescence mostly of sessile terminal heads but sometimes with 1-2 flowers in the axils of the upper leaves; heads with 1-5 flowers; bracts 10-22 × 1.5-3 mm; peduncle absent; bracteoles 4-6 × 1 mm, linear, pedicels 0-3(-9) mm; outer sepals 11-13 × 3-4 mm, broadly lanceolate, abruptly narrowed to a long attenuate apex, pilose; inner sepals ovate but slightly shorter, c. 10 mm long; corolla 2-2.8 cm long, pale pink or white, unlobed, midpetaline bands adpressed pilose, pink; ovary pilose, style pilose, divided 6-8 mm above base, stigmas 3 mm; capsule pilose, 1-seeded (fide Sa’ad 1967), seeds puberulous. [ Sa’ad 1967: 116; Rechinger 1963: 14]

Distribution.

Iran (Grossheim & Schiskin 215, Furse & Synge 664, Merton 3516, Bornmüller 7642, Cowan & Darlington 1487); Iraq; Azerbaijan (Aucher-Eloy 4947, Wendelbo et al. 11891); Armenia (Schelkovnikov s.n. 31/5/1926). Records from Turkey are unconfirmed.

Notes.

The short-pedicellate flowers which give the inflorescence a looser appearance than in related species are noteworthy. The appressed indumentum especially on the stem serves to separate this species from Convolvulus calvertii .
