Type.

TURKEY, Davis & Polunin 23382 (holotype E00285413!; isotypes BM001014567!, K!).

Distinguishing features.

Woody based perennial similar to Convolvulus cataonicus but leaves, bracts and sepals adpressed pilose to subglabrous, sepals gradually acuminate and ovary and style glabrous or very thinly pilose. [ Parris 1978: 211]

Distribution.

Endemic to Turkey and apparently rare.

Notes.

This species may prove only to be a variety or subspecies of Convolvulus cataonicus . It is readily distinguished by the near absence of hairs on the leaves, sepals and ovary, but at least one intermediate is known. Brant & Strangeways 1840 combines absence of hairs with a sepal shape similar to that of Convolvulus cataonicus .
