Gratiola monnieri (Linnaeus) Linnaeus , Systema Naturae, ed. 10, 2: 851. 1759.

["Habitat in America meridionali. Hallman."] Cent. II Pl.: 9 (1756). RCN: 132.

Basionym: Lysimachia monnieri L. (1756) .

Neotype (Cramer in Dassanayake & Fosberg, Revised Handb. Fl. Ceylon 3: 421. 1981): [icon] " Moniera minima repens, foliis subrotundis, floribus singularibus alaribus " in Browne, Civ. Nat. Hist. Jamaica: 269, t. 28, f. 3. 1756.

Current name: Bacopa monnieri (L.) Pennell ( Scrophulariaceae ).

Note: This has been interpreted as a new combination in Gratiola of Lysimachia monnieri L. (1756) because the diagnoses of the two are essentially the same, and the latter does not appear in Syst. Nat., ed. 10, 2 ( May–Jun 1759). Additionally, Linnaeus (in Amoen. Acad. 4: 306. Nov 1959) changed the name L. monnieri to G. " monnieria " in the reprint of the dissertation in which the former had originally appeared, as noted by Nordenstam (in Bot. Not. 114: 278. 1961). Linnaeus’ intention therefore seems clear. Cramer designated a Browne figure as type. Although it was not cited in the synonymy of the basionym, there is no original material in existence so this choice is treated as a neotypification under Art. 9.8.
