Distribution
The species grows on the Heard Island and McDonald, Crozet, Prince Edward and Kerguelen Islands. These remote islands are at roughly 50° South Latitude, constantly buffeted by strong winds. This makes pollination by flying insects impractical, explaining why the Kerguelen cabbage is self-pollinating. At the mature stage, this species exhibits several adaptations linked to cold tolerance such as high polyamine levels.

Famous quotes containing the word distribution:
“My topic for Army reunions ... this summer: How to prepare for war in time of peace. Not by fortifications, by navies, or by standing armies. But by policies which will add to the happiness and the comfort of all our people and which will tend to the distribution of intelligence [and] wealth equally among all. Our strength is a contented and intelligent community.”
—Rutherford Birchard Hayes (1822–1893)
“In this distribution of functions, the scholar is the delegated intellect. In the right state, he is, Man Thinking. In the degenerate state, when the victim of society, he tends to become a mere thinker, or, still worse, the parrot of other men’s thinking.”
—Ralph Waldo Emerson (1803–1882)
“There is the illusion of time, which is very deep; who has disposed of it? Mor come to the conviction that what seems the succession of thought is only the distribution of wholes into causal series.”
—Ralph Waldo Emerson (1803–1882)
