Ranunculus aquatilis Linnaeus, Species Plantarum 1: 556. 1753.

"Habitat in Europae aquis undosis, fossis, rivulis." RCN: 4100.

Lectotype (Cook in Mitt. Bot. Staatssamml. München 6: 123. 1966): Herb. Linn. No. 715.75 (LINN) .

Current name: Ranunculus aquatilis L. ( Ranunculaceae).

Note: Misled by Jackson’s erroneous assertion that 715.75 (LINN) was unavailable to Linnaeus until 1767, Cook designated it as neotype. However, as it is original material, his choice is accepted as being correctable to a lectotype (Art. 9.8).
