Brassica rupestris
Also called Scillian Wild Cabbage
Brassica rupestris is a species of flowering plant in the family Brassicaceae, native to southwestern Italy and Sicily. The plant is known to grow on vertical limestone cliffs. In the past it was proposed, based on morphology, that Brassica rupestris contributed to the ancestry of either kale or kohlrabi, but DNA evidence shows that it did not.
There were a number of substances of note found in the roots and shoots of B. rupestris. These were tartaric acid ester, reduced glutathione (GSH), ascorbic acid, dehydroascorbic acid, glucobrassicin, and glucoraphanin.
Brassica rupestris subsp. rupestris is found in mountainous areas of Calabria and Sicily, and has been reassessed as Least Concern, while B. rupestris subsp. hispida is found in a number of stations in Sicily and has been reassessed as Vulnerable. Both subspecies typically live on near-vertical limestone cliffs, with B. rupestris subsp. rupestris found from 0 to 1,100 m (0 to 3,600 ft) above sea level, and B. rupestris subsp. hispida found from 800 to 1,300 m (2,600 to 4,300 ft).
