Type.

Based on Convolvulus mauritanicus Boiss.

Distinguishing features.

Distinguished by the prominent spreading hairs on the calyx and often also on the stem and leaves.

Distribution.

Morocco (Balls 2934, Lindberg 3902, Gattefossé 3/8/1935), Algeria (Cosson 9/6/1875). Reaches at least 2300 m in Morocco (Jury 17634). It is also widely cultivated and reported to have escaped in Sicily.

Notes.

The flexuose peduncles, prominent bracteoles, essentially broadly oblong leaves and violet flowers make Convolvulus sabatius a relatively distinct species.
