Hedysarum hamatum Linnaeus, Systema Naturae, ed. 10, 2: 1170. 1759.

["Habitat in Jamaica, Zeylona."] Sp. Pl., ed. 2, 2: 1056 (1763). RCN: 5525.

Lectotype (Kirkbride & Kirkbride in Taxon 36: 457. 1987): [icon] " Anonis non spinosa minor, glabra, procumbens, flore luteo " in Sloane, Voy. Jamaica 1: 187, t. 119, f. 2. 1707. - Typotype: Herb. Sloane 3: 94 (BM-SL) .

Current name: Stylosanthes hamata (L.) Taub. ( Fabaceae: Faboideae).

Note: The autonymic varietal epithet was established in Pl. Jam. Pug: 20 (1759). Fawcett & Rendle (Fl. Jamaica 4: 28. 1920) excluded the Burman element and indicated (unspecified) material in BM as type. It seems likely that they intended Sloane material but this was, in any case, not seen by Linnaeus and is not original material for the name.
