No interactions present.
The leaflets are cordate (heart shaped) which is not consistent with Fool's watercress.
Also, pinnate leaf with bright green leaflets.
I'm using The Wild Flower Key (Rose 2006) but can't seem to quite get there with this one...
Help much appreciated!
There is also no axil between the leaflets and stalk....
