Type.

Based on Convolvulus cneorum Forssk.

Description.

Undershrub from a woody base to 35 cm, the lower branches woody and spinescent, younger brances herbaceous; vegetative parts softly white-tomentose with spreading hairs. Leaves sessile, 1-3 × 0.3-0.5 cm, oblanceolate below, oblong above, acute, margin entire, base cuneate. Flowers in subsessile heads along the upper part of the stem; bracts oblong-elliptic to ovate; peduncles 0-5 mm; bracteoles 10 × 5 mm, ovate; pedicels absent; outer sepals 10 × 4 mm ovate, acute; inner sepals 7 × 2 mm, lanceolate, much narrower than outer sepals; corolla 1.8-2.3 cm, pale pink or white, somewhat undulate, midpetaline bands pilose; ovary and style glabrous; style divided 5 mm above base, the stigmas 4 mm. Capsule glabrous; seeds smooth, glabrous (fide Feinbrun-Dothan 1978: 37). [ Sa’ad 1967: 80; Parris 1978: 203 p.p.; Boulos 2000: 331; Strid and Strid 2010: 4-5 (plate].

Distribution.

Lower Egypt and Sinai (Schweinfurth 2148, 1246; Keller 32; Boulos et al. 20333, 20349; Danin S-1990, Davis 10540, Schimper 727); Palestine/Israel: Negev (Zohary 7325); Turkey (Palmer T/60). The occurrence of this species in Turkey is correct, although unexpected, but records from other countries including Arabia are probably errors.

Notes.

Replaces Convolvulus secundus in Egypt and Sinai. Differs principally in habit, forming a compact spiny bushlet, the lower branches and side shoots woody and spinescent. The sepals and bracteoles are more densely villous with the flower heads almost contiguous.
