Description.

Perennial herb from a taproot with trailing (sometimes twining) stems to at least 75 cm, vegetative parts pubescent with adpressed or spreading hairs. Leaves petiolate, very plastic in shape, more or less trimorphic; petioles 0.3-3 cm, diminishing in length upwards; lowermost leaves 1-3 × 0.6-1.5 cm, deltoid, acute, margin undulate to crenate, base truncate and shortly cuneate onto the petiole; lower leaves sometimes distinct, 3-4 × 3-4 cm, deeply laciniate; middle leaves with elongate oblong undulate- or crenate-margined middle lobe, 2.5-3.5 × 0.4-0.8 cm and deeply lobed, more or less laciniate auricles; upper leaves with a very narrowly oblong central lobe 2-3.5 × 0.2-0.5 cm, two slightly shorter ascending lateral lobes and smaller bifurcate basal lobes. Flowers solitary or paired, pedunculate, axillary, not recurved in fruit; peduncles 0.6-3 cm; bracteoles 1-2 mm, filiform; pedicels 3-8 mm; sepals 4-5 × 2.5-4 mm, obovate or elliptic, acute or rounded, mucronate, pubescent; corolla 7-9 mm, white or pink, weakly lobed, midpetaline band pubescent; ovary and style glabrous; style divided 2-3 mm above base, stigmas c. 1.5 mm.

Notes.

This species is extremly variable in leaf form and flowering specimens are indistinguishable from Convolvulus recurvatus .
