Comment: Site remark: Roadsite and edge of garden at Ålsgårde, with permission from owner of garden. The site was newly disturbed and acutely threatened by weeding and general road maintenance. Species and subspecies identified from a few flowering plants with vertical siliques, that had survived weeding/gardening. Multiple (ca. 40) young rosette plants collected and transported to the collector’s garden at Radiomarken, Bagsværd, Greater Copenhagen, Denmark. Cultivated to flowering and seed set (30+ flowering plants) the year after, in the absence of any nearby Barbarea during flowering. Vertical siliques (subspecies character) consistent in all resulting flowering plants, the species and subspecies identity of which were controlled by the collector. Harvest by the collector 15-30 July 2019.; Estimated population: 200 Plants
