3b. Convolvulus sabatius subsp. mauritanicus (Boissier) Murbeck (1923: 2) Basionym: C. mauritanicus Boissier (1839: 418). Holotype: ALGERIA. Constantine, Sejourne, s.n. (G-Boiss) Convolvulus sabatius var. atlantius Ball (1878). Basionym: C. mauritanicus Boissier (1839: 418). Holotype: Morocco, in covalle Ait Mesan, Ball s.n., 13–16 May 1871 (P!) 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. A specimen from Rome (Heard s.n., BM) is referable to this subspecies. 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 slopes. Phenology:— Flowering and fruiting April–August. Conservation:— Whilst this subspecies has a highly disjunct distribution, it is locally common or abundant and meets the criteria of Least Concern (IUCN 2001). Other specimens seen:— ALGERIA.
