Convolvulus littoralis Linnaeus, Systema Naturae, ed. 10, 2: 924. 1759.
["Habitat in America."] Sp. Pl., ed. 2, 1: 227 (1762). RCN: 1269.
Lectotype (Austin in Woodson & Schery in Ann. Missouri Bot. Gard. 62: 199. 1975): [icon] " Convolvulus foliis obtusis, palmato-lobatis " in Plumier in Burman, Pl. Amer.: 79, t. 90, f. 2. 1756.
Current name: Ipomoea imperati (Vahl) Griseb. ( Convolvulaceae).
Note: La Valva & Sabato (in Taxon 32: 112, f. 3. 1983) also treat the Plumier plate as the type, and reproduce it. Its identity was discussed by these authors, and by Austin & Bianchini (l.c. 47: 837. 1998), who argue that it is recognisable as I. imperati .
