Rorippa species - Yellow-cresses
Rorippa palustris - Marsh Yellow-cress
The sepals are about the same length as the petals, whereas the petals are longer in R. sylvestris
Rorippa sylvestris - Creeping Yellow-cress
The main difference from the similar R. palustris is that the petals are longer than the sepals.
