Najas marina Linnaeus, Species Plantarum 2: 1015. 1753.

"Habitat in Europae maribus." RCN: 7354.

Lectotype (Viinikka in Ann. Bot. Fenn. 13: 128. 1976): Herb. Linn. No. 1156.1 (LINN) .

Generitype of Najas Linnaeus.

Current name: Najas marina L. ( Najadaceae).

Note: Casper (in Feddes Repert. 90: 217. 1979) designated a Vaillant illustration as the lectotype but Viinikka’s choice of 1156.1 (LINN) has priority and, as the annotations on the sheet support the contention that the sheet was in Linnaeus’ possession in 1753, there seem to be no valid grounds for rejecting this choice.
