Arabis thaliana Linnaeus, Species Plantarum 2: 665. 1753.

"Habitat in Europae septentrionalioris sabulosis." RCN: 4837.

Lectotype (Anon in Haussknechtia, Beih. 8: 43. 1997): [icon] "Pilosella siliquata" in Thal, Sylv. Here.: 84, t. 7, f. D. 1588.

Current name: Arabidopsis thaliana (L.) Heynh. ( Brassicaceae).

Note: Franchetti (in Webbia 14: 207. 1958) stated that the type should be a Clifford specimen, if in existence, or the Thal plate if not. Jonsell (in Polhill, Fl. Trop. E. Africa, Cruciferae: 45. 1982) chose 842.5 (LINN) as lectotype. This sheet lacks a Species Plantarum number (i.e. “3”) and, coming from Löfling, is not believed to be original material for the name. However, the Thal plate has subsequently been formally designated as lectotype (by an unknown author).
