Sisymbrium pyrenaicum Linnaeus, Systema Naturae, ed. 10, 2: 1132. 1759, nom. illeg. ["Habitat in Pyrenaeis, Helveticis alpibus."] Sp. Pl., ed. 2, 2: 916 (1763). RCN: 4779. Lectotype (López González in Anales Jard. Bot. Madrid 52: 102. 1994): Herb. Linn. No. 836.4 (LINN). Current name: Rorippa islandica (Gunnerus) Borbás (Brassicaceae). Note: See extensive discussion on the correct name for this taxon by López Gonzólez (in Anales Jard. Bot. Madrid 52: 102. 1994). He indicates 836.4 (LINN) as the lectotype, allegedly following Ball (in Feddes Repert. 64: 14. 1962), and reproduces the Morison figure (as his f. 1 on p. 98). Although Ball discussed the identity of this sheet and the Allioni figure (probably Rorippa pyrenaica (All.) Rchb.), he did not choose a type, concluding "As the name is illegitimate, the confusion and doubt as to the identity of this species does not have any serious nomenclatural consequences". It is illegitimate because it is a later homonym of S. pyrenaicum Loefl. (1758). ... : Published as part of Jarvis, Charlie, 2007, Chapter 7: Linnaean Plant Names and their Types (part S), pp. 806-877 in Order out of Chaos.
