Alisma ranunculoides Linnaeus, Species Plantarum 1: 343. 1753.

"Habitat in Gotlandiae, Belgii, Angliae, Galliae fossis." RCN: 2633.

Lectotype (designated here by Jonsell): Bergius, s.n., Herb. Linn. No. 473.6 (LINN) .

Current name: Baldellia ranunculoides (L.) Parl. ( Alismataceae).

Note: The material in LINN (473.6 and 473.7) was collected in Gotland, as indicated on the sheets, and agrees with the current usage of this name. The material on 473.7 was apparently collected on Linnaeus’ journey to Gotland in 1741 but no specific epithet is written upon it. On sheet 473.6 is written (on the reverse) "Gotlandia Bergius", which means that it was collected by Linnaeus’ student Peter Jonas Bergius on Gotland in 1752. It should have reached Linnaeus, together with some other Bergius specimens from Gotland, later the same year, when Species Plantarum was still in preparation, though at an advanced stage. The epithet, together with the Species Plantarum number “6”, is written on the front of the sheet, and this sheet is therefore selected here as the lectotype.
