Rorippa palustris
(Map updated: March 2008)

A common plant of lake shores, ponds, sides of drainage ditches and similar wet habitats. The stems are mainly erect-growing, unlike the similar and much rarer Rorippa islandica. Flowers are small and yellow, succeeded by small fat 'pods'.

All names: Rorippa palustris (L.) Besser; Rorippa islandica auct. non (Oeder ex Murray) Borbas; Radicula islandica (Oeder) Druce; Radicula palustris (L.) Moench
