Silphium trilobatum Linnaeus, Systema Naturae, ed. 10, 2: 1233. 1759.

["Habitat in America."] Sp. Pl., ed. 2, 2: 1303 (1763). RCN: 6652.

Lectotype (Howard, Fl. Lesser Antilles 6: 616. 1989): [icon] "Buphthalmum caule repente" in Plumier in Burman, Pl. Amer.: 97, t. 107, f. 2. 1757.

Current name: Sphagneticola trilobata (L.) Pruski ( Asteraceae).

Note: Moore (in Fawcett & Rendle, Fl. Jamaica 7: 227. 1936) noted the existence of 1032.9 (LINN) but did not indicate it as type. Similarly, although D’Arcy (in Ann. Missouri Bot. Gard. 62: 1168. 1975) suggested the name was based on a Plumier plate, he did not designate it as type, and Howard appears to have been the first to formalise a choice.
