It took a long time to learn the identity of this plant. I left a specimen with the Tasmanian Herbarium, but before being told what it was I moved to Victoria. Some time later I took a specimen of Barbarea intermedia to the Victorian Herbarium. They produced a specimen of Barbarea australis for comparison and to my amazement it was part of the specimen I had lodged in Tasmania labelled collected by Ken Harris in Waddamana, Tasmania!
