Acaena antarctica is a small herbaceous plant in the Rosaceae family native to Argentina, Chile and the Falkland Islands. [1]
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.

An internationally important botanical research and education institution, it employs 1,100 staff. Its board of trustees is chaired by Dame Amelia Fawcett.
Sir Joseph Dalton Hooker was a British botanist and explorer in the 19th century. He was a founder of geographical botany and Charles Darwin's closest friend. For twenty years he served as director of the Royal Botanical Gardens, Kew, succeeding his father, William Jackson Hooker, and was awarded the highest honours of British science.
Acaena is a genus of about 60 species of mainly evergreen, creeping herbaceous perennial plants and subshrubs in the family Rosaceae, native mainly to the Southern Hemisphere, notably New Zealand, Australia and South America, but with a few species extending into the Northern Hemisphere, north to Hawaii and California.
Microseris scapigera is a yellow-flowered daisy, a perennial herb, found in New Zealand and Australia. It is the only New Zealand species of Microseris, and one of three Australian species along with Microseris lanceolata and Microseris walteri. It is classified in a group of plants, the tribe Cichorieae, that includes chicory and dandelion.
Megaherbs are a group of herbaceous perennial wildflowers growing in the New Zealand subantarctic islands. They are characterised by their great size, with huge leaves and very large and often unusually coloured flowers, which have evolved as an adaptation to the harsh weather conditions on the islands.
Eucalyptus macrocarpa, commonly known as mottlecah, is a species of mallee that is endemic to the south-west of Western Australia. It has smooth bark, usually sessile, heart-shaped adult leaves arranged in opposite pairs, large red flowers and broad conical fruit.
Nothofagus betuloides, Magellan's beech or guindo, is a tree native to southern Patagonia.
Ipomoea chrysocalyx is a vine in the family Convolvulaceae. It is endemic to Ecuador. Its natural habitat is subtropical or tropical dry forests.
Rhizanthes zippelii is a species of parasitic flowering plant without leaves, stems, roots, or photosynthetic tissue. Its flowers bud out of the roots of the Tetrastigma vine. It is found in the tropical rainforests of Java. The flowers are reddish-brown, with long hanging tips, and are from 12 to 29 cm across.
Lachnostachys is a genus of flowering plants in the mint family, Lamiaceae, first described in 1842 by William Jackson Hooker. The type species is Lachnostachys ferruginea.

The Flora Antarctica or formally and correctly The Botany of the Antarctic Voyage of H.M. Discovery Ships Erebus and Terror in the years 1839–1843, under the Command of Captain Sir James Clark Ross, is a description of the many plants discovered on the Ross expedition, which visited islands off the coast of the Antarctic continent, with a summary of the expedition itself, written by Joseph Dalton Hooker and published in parts between 1844 and 1859 by Reeve Brothers in London. Hooker sailed on HMS Erebus as assistant surgeon.
The Ross expedition was a voyage of scientific exploration of the Antarctic in 1839 to 1843, led by James Clark Ross, with two unusually strong warships, HMS Erebus and HMS Terror. It explored what is now called the Ross Sea and discovered the Ross Ice Shelf. On the expedition, Ross discovered the Transantarctic Mountains and the volcanoes Erebus and Terror, named after his ships. The young botanist Joseph Dalton Hooker made his name on the expedition.
The Flora Novae-Zelandiae is a description of the plants discovered in New Zealand during the Ross expedition written by Joseph Dalton Hooker and published by Reeve Brothers in London between 1853 and 1855. Hooker sailed on HMS Erebus as assistant surgeon. It was the third in a series of four Floras in the Flora Antarctica, the others being the Flora of Lord Auckland and Campbell's Islands (1843–45), the Flora of Fuegia, the Falkland Islands, etc (1845–47), and the Flora Tasmaniae (1853–59). They were "splendidly" illustrated by Walter Hood Fitch.
The Flora Tasmaniae is a description of the plants discovered in Tasmania during the Ross expedition written by Joseph Dalton Hooker and published by Reeve Brothers in London between 1855 and 1860. Hooker sailed on HMS Erebus as assistant surgeon. Written in two volumes, it was the last in a series of four Floras in the Flora Antarctica, the others being the Flora of Lord Auckland and Campbell's Islands (1843–45), the Flora of Fuegia, the Falkland Islands, etc (1845-47), and the Flora Novae-Zelandiae (1851–53). They were "splendidly" illustrated by Walter Hood Fitch.
The Flora of Lord Auckland and Campbell's Islands is a description of the plants discovered in those islands during the Ross expedition written by Joseph Dalton Hooker and published by Reeve Brothers in London between 1843 and 1845. Hooker sailed on HMS Erebus as assistant surgeon. It was the first in a series of four Floras in the Flora Antarctica, the others being the Flora of Fuegia, the Falklands, Kerguellen's land, etc (1845–1847), the Flora Novae-Zelandiae (1851–53), and the Flora Tasmaniae (1853–59).
