Alyssum hyperboreum Linnaeus, Species Plantarum 2: 651. 1753.

"Habitat in America septentrionali. D. Krascheninnikof." RCN: 4731.

Lectotype (Berkutenko in Linzer Biol. Beitr. 27: 1116. 1995): Herb. Linn. No. 828.6 (LINN; iso- LE) .

Current name: Schivereckia hyperborea (L.) Berkut. ( Brassicaceae).

Note: Berkutenko concluded from her study that 828.6 (LINN) and the Krasheninnikov plate both belong to what had been called Schivereckia podolica (Bess.) Andrz., a plant from E Russia, N Ukraine, and NE Romania, and not to the Pacific plant long known as Draba hyperborea (L.) Desv. She made the new combination S. hyperborea (L.) Berkut., and took up D. grandis Langsd. as the correct name for the Draba species.
