Description.

Perennial herb with stout somewhat woody rootstock from which arise various short decumbent, subglabrous, pubescent to pilose stems to 50 cm. Leaves petiolate, 0. 8-3.2 × 7.5-3.5 cm, ovate-deltoid or reniform, rounded to obtuse, margin undulate to coarsely serrate, base cordate, usually shortly and softly tomentose-sericeous but sometimes with longer hairs, occasionally subglabrous; petioles 0.5-0 7 cm, often flexuose. Flowers solitary, borne on axillary peduncles; peduncles 0-1 cm; bracteoles 2.5-7 mm, filiform; pedicels 1-8.5 cm, commonly flexuose and somewhat deflexed in fruit; calyx in flower clearly longer than broad, sepals 4.5-9 × 3-6 cm, lanceolate to linear-oblong, acute to apiculate forming a narrow calyx, the inner sepals broader; corolla 2.2-3(-4) cm long, pink with a darker centre, midpetaline bands sericeous near apex; filaments glandular below; ovary glabrous; style glabrous, divided c. 7 mm above base; stigmas 3-4 mm. Capsule glabrous; seeds finely tuberculate. [ Sa’ad 1967: 239]

Notes.

Distinguished from Convolvulus vidalii and Convolvulus glaouorum by the narrow calyx (lanceolate in outline) and the narrow sepals which are much longer than broad. This species is divided into two varieties:
