Convolvulus sabatius f. genuinus Maire in Emberger & Maire (1929: 43), nom. non rite public. Calyx lobes sparsely to densely villous. Distribution:— Morocco (western Rif, and the High and Middle Atlas mountains) and Algeria (Kabylie and Mts de Bibans areas of Algeria; fig. 2b). This subspecies is widely cultivated as an ornamental.

We were unable to see any material from Sicily, but C. sabatius is considered introduced there (Giardina et al. 2007) and it is possible that plants from Sicily are escapes from cultivation also referable to subsp. mauritanicus . Habitat:— Dry, rocky, limestone ... : Published as part of Carine, Mark A. & Robba, Lavinia, 2010, Taxonomy and evolution of the Convolvulus sabatius complex (Convolvulaceae), pp. 1-21 in Phytotaxa 14 on pages 18-20, DOI: 10.11646/phytotaxa.14.1.1, http://zenodo.org/record/4778706 ...
