TURKEY, Eski-Scheher, Warburg & Endlich 515 (holotype B!).

Description.

Compact cushion-forming undershrub with thick woody taproot, branched at base with short woody prostrate to ascending branches to c. 15 cm, young stems sericeous. Leaves sessile, 1.2-2 × 0.3-0.4 cm, linear-oblanceolate, acute, attenuate at the base, sericeous and with some spreading hairs. Flowers solitary, axillary, shortly pedunculate but becoming crowded, sessile and subcapitate towards the branch tips; peduncles 0-5 mm, pilose; bracts leaf-like; bracteoles similar but shorter; sepals 8-11 × 3 mm, oblong, acute to apiculate, concave, adpressed pilose, not bicoloured; corolla 1.7-2.3 cm long, white with distinct pink, pubescent midpetaline bands, unlobed; ovary pilose; style glabrous, divided c. 4 mm above base; stigmas 4 mm. Capsule and seeds unknown.

Distribution.

Endemic to Turkey (Rechinger 61014, Fitz & Spitzenberger 721, Sorger s.n. [28/5/1964]).

Notes.

Could be confused with Convolvulus boissieri subsp. compactus but the 1-nerved, near linear leaves are distinct.

Although Parris (1978: 209) treated Convolvulus phrygius and Convolvulus pulvinatus as distinct species, they were collected at the same place and the distinctions in measurements are minor. The corollas are similar in size and the sepals are only about 2 mm different in length. There is no good reason to treat them as separate species.
