Barbarea australis, commonly known as native wintercress or riverbed wintercress, is a morphologically and ecologically typical Barbarea species with an unusual distribution: it is an endemic and threatened species from Tasmania.^[4] The leaves have a large end-lobe and only few side lobes, much like the leaf-shape of Barbarea stricta and Barbarea orthoceras. With regard to defence chemicals (glucosinolates), it is similar to other members of the genus.^[5]

Cultivation

Although the plant remains critically endangered in the wild, Native wintercress is available for home garden cultivation. All above-ground parts of the plant are edible, with the leaves tasting similar to rocket.^[6]
