Convolvulus nummularius Linnaeus, Species Plantarum 1: 157. 1753.

"Habitat in Jamaicae & Barbados pratis." RCN: 2175.

Basionym of: Evolvulus nummularius (L.) L. (1762) .

Lectotype (Verdcourt in Jarvis & al., Regnum Veg. 127: 16. 1993): [icon] " Convolvulus minor repens, nummulariae folio, flore coeruleo " in Sloane, Voy. Jamaica 1: 157, t. 99, f 2. 1707. - Typotype: Herb. Sloane 3: 19 (BM-SL) .

Current name: Evolvulus nummularius (L.) L. ( Convolvulaceae).

Note: Ooststroom (in Meded. Bot. Mus. Herb. Rijks Univ. Utrecht 14: 115, 120. 1934) indicated what is evidently 393.1 (LINN) as type. However, this is not original material for the name, and Verdcourt (in Hubbard & Milne-Redhead, Fl. Trop. E. Africa Convolvulaceae: 16. 1963) and Stearn (in Taxon 21: 647. 1972) instead treated material in Sloane’s herbarium as the type. Despite the close relationship between Sloane’s specimens and his published illustrations, the former were not studied by Linnaeus. Consequently, Verdcourt’s (1993) indication of Sloane’s illustration as the type is accepted as the earliest typification.
