A new taxon Biscutella laevigata subsp. woycickii (Brassicaceae) is described from southern Poland. The taxon is similar to B. laevigata subsp. gracilis, but differs in having thin, light-green rosette leaves very densely covered by simple non-glandular trichomes, smaller seeds and the ability to tolerate and accumulate high amounts of heavy metals. This new taxon is supported by results of cultivation experiments, as well as genetic and paleobotanical evidence.
