Murbeckiella pinnatifida Murbeckiella
Also sometimes known as Sisymbrium pinnatifidum, this small crucifer looks like a Cardamine species and we had several attempt at identifying it before realising that leaves, hairs and slightly notched petals were characteristic of this Pyrenean, rock loving species.
M. pinnatifida grows in mountainous regions of Spain and the southern Alps as well as the Pyrenees.
