Distribution.
Egypt: Sinai (
Bove
503,
Danin
s.n. [28/5/1962]), Jordan: Wadi Sirhan (
Hunting Survey
117a). Apparently very rare.
Notes.
Differs from the two previous species in the pedunculate heads but superficially identical to
Convolvulus cephalopodus subsp. bushiricus
, from which it is distinguished by the glabrous ovary. Very similar to
Convolvulus schimperi
differing in the ascending habit and in the leaves which are not undulate.
The lectotype is a meagre specimen and all the other cited specimens represent more complete material.
