ID: All leaves bristly, many of the lower leaves with a large lobe on one side near the base, as well as sometimes small leaflets below the main leaf-blade.  Upper leaves do not clasp stem as in Brassica, and are not lobed but merely toothed.  Pod has a conical beak which is more than a third of the pod's overall length (including beak).

Other features: Sepals spreading at various angles, usually some downturned or horizontal, not appressed to the petal-tube.
