Type.

IRAQ, between Kirkuk and Sulaymaniyah, Haussknecht 653 (lectotype G, designated by Sa’ad 1967: 105).

Description.

Undershrub with fastigiate branches to 40 cm, stems appressed pubescent. Leaves sessile, the basal leaves 2.5-6 × 0.5-3 cm, oblanceolate, acute to obtuse, attenuate at the base, appressed pubescent; stem leaves linear 1.5-3.5 × 0.2-0.4 cm. Flowers axillary, solitary or paired forming a lax, sparsely branched inflorescence, which is commonly dichasial in structure apically; peduncles 0.5-2 cm long, slender, bracteoles minute; pedicels 2-6 mm; sepals 6-7 × 3-4 mm, elliptic to obovate, mucronate, the margins scarious, the inner sepals narrower; corolla 12 mm long, white, midpetaline bands pubescent; ovary comose; style pilose, divided 4 mm above base, stigmas 1-2 mm. Capsule not seen. [ Sa’ad 1967: 105]

Distribution.

Iraq (Helbaek 1726, Haussknecht s.n. [6/1867]); Iran (Koelz 15840).

Notes.

This species is distinguished by the relatively large, glabrous sepals and narrow, sparingly branched inflorescence which is clearly cymose in structure apically. It seems close to Convolvulus pseudocantabrica subsp. askabadensis but the ovary is hirsute and the corolla smaller.
