Almost restricted to Oman (Mandaville 3446, 6230; Popov 57/86, Lebrun 91, McLeish 3561, Edmondson 3285); United Arab Emirates (fide Jongbloed 2003: 315).

Notes.

A little-known species similar to Convolvulus acanthocladus , differing in the obovate leaves, flowers arranged in sessile, axillary clusters and elliptic bracteoles. The corolla size may also be significant.
