Taxonomy and naming

Acaena antarctica was first formally described in 1846 by Joseph Dalton Hooker.[1][2] Kew holds specimens collected by Hooker from Hermite Island, Cape Horn on the Ross expedition.[3]

The genus name Acaena is derived from the Ancient Greek word akaina meaning "thorn" or "spine",[4] referring to the spiny calyx of many species of Acaena. The specific epithet, antarctica, derives from the Greek (anti, "opposite" and arktos, "bear") and designates the place opposite the constellations of the Great and the Little Bear, thus describing the species as coming from south of the South Pole circle.[5]
