Potentilla opaca Linnaeus, Systema Naturae, ed. 10, 2: 1064. 1759, nom. illeg.

["Habitat in Helvetia."] Cent. I Pl.: 13 (1755). RCN: 3788.

Replaced synonym: Potentilla heptaphylla L. (1755) .

Type not designated.

Original material: as replaced synonym.

Current name: Potentilla heptaphylla L. ( Rosaceae).

Note: As noted by Nordenstam (in Bot. Not. 114: 277. 1961), P. opaca replaced P. heptaphylla L. (1755) in the reprint of the dissertation Cent. I Pl. in Amoen. Acad. 4: 274. 1759). Potentilla opaca was, in fact, first published earlier ( May–Jun) in 1759 in Syst. Nat., ed. 10, 2: 1064, but it is in any case a replacement name for P. heptaphylla, and is illegitimate.
