Distribution: Egypt to Pakistan and India.

Comment/Acknowledgements: Common on open, waste, dry and sandy soils throughout the Punjab plains, Karachi, Sind and Baluchistan areas. A species very variable in pubescence, size and shape of leaf and length of peduneles.

Convolvulus prostratus was misidentified and given as a synonym of Convolvulus pentapetaloides L. by Vahl (Sym. 2:36.1791). The 2 however are distinct (Sa’ad, l.c. 193), being geographically separated as well. Convolvulus prostratus is a Saharo-Sindian species, wh ile Convolvulus pentapetaloides is a Mediterranean species. Convolvulus prostratus has also been equated with Convolvulus microphyllus Sieb. ex Spreng (Sa’ad, l.c.).

A specimen at Edinburgh from Sibi, Baluchistan, Lace 3397 and determined by Sa’ad as Convolvulus cancerianus Abdallah & Sa’ad (a species from Egypt and Arabia) is probably referable to Convolvulus prostratus.

The plant is eaten by cattle, used as a vegetable and as a coolant in hot weather.
