Perennial herb with tap root and stems somewhat woody below, similar in all details to Convolvulus scammonia but stems erect to 60 cm, leaves 1.5-5 × 0.3-0.8 cm, sagittate, the central lobe narrowly oblong-lanceolate, basal auricles small, simple. The peduncles appear always to bear only 1-2 flowers and the bracteoles are filiform, not more than 0.5 mm wide. [ Sa’ad 1967: 242; Parris 1978: 218]

Molecular studies ( Williams et al. 2014) confirm that this is a distinct species related to but distinct from Convolvulus scamonia .
