Type: Described from C. Europe.
Distribution: Chiefly European species, now widely spread in C. and W. Asia, introduced elsewhere.
There can be no doubt that the above cited specimen is true C.draba. It appears to be a recent introduction in our area. Careful collection may now reveal its wider occurrence in W. Pakistan also. The seeds have spicy flavour and may be used as a substitute for pepper.
