The Kerguelen cabbage, Pringlea antiscorbutica (Brassicaceæ). The sole species of its genus, this megaherb is native to the remote Kerguelen archipelago (also known as the Desolation Islands), a French territory in the subantarctic Indian Ocean, as well as a few other small islands belonging to France, Australia, and South Africa. The species is well-adapted to the harsh conditions it experiences on all of these islands; it is self-pollinated, contains high levels of endogenous polyamines for protection against cold damage, and grows thick anchoring tissues to hold itself in the ground. Its Latin specific epithet, chosen by the great botanist J.D. Hooker of Kew, derives from its use by sailors against scurvy.
