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
[edit]A. polaris was used as a food source and a scurvy preventative by early explorers and sealers.[2][3] It was eaten by the survivors of the 1907 shipwreck of the Dundonald on Disappointment Island.[4][3]
Conservation status
[edit]It is classified as "At Risk - Naturally Uncommon" in the New Zealand threatened plants classification system.[5] On Macquarie Island, it was threatened by introduced black rats and European rabbits,[2] until their eradication in 2011.
