Distinguishing features.

Distribution.

Pakistan (Ghafoor & Goodman 4829, Popov 29); Iran (Wendelbo & Foroughi 15571A), Merton 3616, Léonard 5913, Grey-Wilson & Hewer 286); Bahrain (Good 192); U.A.E. (Ghazanfar 4254, Western 258); Qatar (Boulo s 11145); Saudi Arabia (Collenette 5281); Oman (Radcliffe-Smith 3907, Gallagher 6692, Guichard KG/83/Oman).

Notes.

One collection from Iranian Baluchestan (Pierce s.n. [11/1880]) appears to be intermediate with Convolvulus pyrrotrichus .

Fruiting heads often become distinctly scorpioid in structure as in Western 421, Ghazanfur 4254 & Osborne 602. Occasionally the heads are sessile as in Collenette 4159 and 9385 from Saudi Arabia and Parsa 565 from Iran; these forms resemble Convolvulus kotschyanus morphologically but can be distinguished by the undulate leaves and hirsute ovary.
