Description.

Weakly cushion-forming plant with a woody rootstock, from which arise ascending stems to 45 cm, vegetative parts pilose with somewhat stiff spreading hairs. Basal leaves 3-8 × 0.5-0.9 cm, oblong-oblanceolate, acute, entire, base long-attenuate and petiole-like up to 4 cm in length; stem leaves 2-5 × 0.5-1 cm, oblanceolate to oblong, acute, entire, base cuneate to attenuate. Flowers in sessile (above) or shortly pedunculate (below) 2-3-flowered axillary heads; bracts usually <3 cm long, lanceolate (if longer, than narrowly lanceolate); peduncles 0-1.5 cm; bracteoles 9-11 × 1 mm, linear-oblong, acute, densely pilose; pedicels absent; outer sepals 9-11 × 2-2.5 mm, lanceolate, acuminate, densely pilose; inner sepals 8-9 × 1 mm, linear-lanceolate; corolla 2-2.5 cm long, pink, shallowly lobed, midpetaline bands darker, adpressed pilose; ovary glabrous; style glabrous, divided 3 mm above base, stigmas 4.5-5 mm; capsule glabrous; seeds glabrous. [ Sa’ad 1967: 162; Austin and Ghazanfar 1979: 19]

Distribution.

Pakistan; southern Iran (Davis & Bokhari 55970, Macmillan 225, Koelz 15039, Stutz 979, Stapf 298); Iraq (Thamer 47695).

Notes.

This species has been confused with Convolvulus prostratus , but is distinguished by its much larger corolla, monocoloured sepals and more developed cushion-like base. It has also been confused with Convolvulus pyrrotrichus but is distinguished by the narrower, lanceolate bracts <3 × 1 cm.
