Europe, Caucasia, Syrian Desert, N. Iran. In Turkey mainly in the Ir.-Tur. region. The commonest Anatolian species, with a superficial resemblance to Sisymbrium, due to the inconspicuous beak, and to Diplotaxis on account of the torulose pods. B. elongata is very variable in leaf shape and indumentum, and,as with all species of the genus, several varieties have been described to cover some aspects of its polymorphism. Two were recognised by Schulz as occurring in Turkey: var. integrifolia Boiss., with narrow oblong leaves and glabrous stems, and var. scabra O. E. Schulz with stiff retrorse hairs at the base of the stem.
