Rorippa Scopoli. Yellow Cress, Marshcress.
A genus of about 75 species, herbs, cosmopolitan. The separation of Nasturtium from Rorippa is warranted (Al-Shehbaz & Price 1998); Franzke et al. (1998) provide corroboration based on molecular analysis. The species treated here as R. aquatica has been placed in several genera in recent years.
