Rorippa austriaca (Crantz) Besser[FNA7, HC2]
Austrian yellowcress field-cress

Publication: Enum. Pl. 103. (as Roripa). 1821.

Origin: Introduced from Europe

selected vouchers: WTU

Notes: We use the earlier combination by Besser (1822), not that of Spach (1838) found in Abrams.

This species is classified as a noxious weed in WA, however few supporting specimens have been seen. Some reports (KZ99; a R. Old pers. comm.) may be based on Rorippa × armoracoides (Tausch) Fuss, the hybrid between R. austriaca and R. sylvestris (L.) Besser, which has been called Rorippa prostrata (Bergeret) Schinz & Thell. in the North American literature.
