Azorella polaris

Azorella polaris, commonly known as the Macquarie Island cabbage, is a species of flowering plant usually placed in the family Araliaceae and only very distantly related to cabbage. It is a megaherb, growing up to about a metre in height, native to the subantarctic islands of New Zealand and to Australia’s Macquarie Island.

Uses
A. polaris was used as a food source and a scurvy preventative by early explorers and sealers. It was eaten by the survivors of the 1907 shipwreck of the Dundonald on Disappointment Island.

Conservation status
It is classified as "At Risk - Naturally Uncommon" in the New Zealand threatened plants classification system. On Macquarie Island, it was threatened by introduced black rats and European rabbits, until their eradication in 2011.
