|Genus:|| Drimys |
J.R.Forst. & G.Forst.
Drimys is a genus of about eight species of woody evergreen flowering plants, in the family Winteraceae. The species are native to the Neotropics, ranging from southern Mexico to the southern tip of South America. They are primitive dicots, associated with the humid temperate Antarctic flora of the Southern Hemisphere, which evolved millions of years ago on the ancient supercontinent of Gondwana. Members of the family generally have aromatic bark and leaves, and some are used to extract essential oils.
D. confertifolia is endemic to the Juan Fernández Islands, 670 km off the Chilean coast, where it forms a dominant tree in the tall lowland forests and lower montane forests of the islands.
The genus formerly included a number of species from Australasia, including Tasmanian pepper (D. lanceolata). Recent botanical studies have led to a growing consensus of botanists to split the genus into two, with the Neotropical species remaining in genus Drimys, and the Australasian species classified in genus Tasmannia (Doust et al. 2004).

The Juan Fernández Islands are a sparsely inhabited island group in the South Pacific Ocean reliant on tourism and fishing. Situated 670 km off the coast of Chile, they are composed of three main volcanic islands: Robinson Crusoe, Alejandro Selkirk and Santa Clara. The group is considered part of Insular Chile.
Hordeum is a genus of annual and perennial plants in the grass family. They are native throughout the temperate regions of Africa, Eurasia, and the Americas.
The Valdivian temperate forests (NT0404) is an ecoregion on the west coast of southern South America, in Chile and extending into Argentina. It is part of the Neotropical ecozone. The forests are named after the city of Valdivia. The Valdivian temperate rainforests are characterized by their dense understories of bamboos, ferns, and for being mostly dominated by evergreen angiosperm trees with some deciduous specimens, though conifer trees are also common.
The Magellanic subpolar forests are a terrestrial ecoregion of southernmost South America, covering parts of southern Chile and Argentina, and are part of the Neotropic ecozone. It is a temperate broadleaf and mixed forests ecoregion, and contains the world's southernmost forests.
Winteraceae is a primitive family of tropical trees and shrubs including 60 to 90 species in five genera. It is of particular interest because it is such a primitive angiosperm family, closely related to Magnoliaceae, though it has a much more southern distribution. Plants in this family grow mostly in the southern hemisphere, and have been found in tropical to temperate climate regions of Malesia, Oceania, eastern Australia, New Zealand, Madagascar and the Neotropics, with most of the genera are concentrated in Australasia and Malesia. Drimys is found in the Neotropical realm, from southern Mexico to the subarctic forests of southern South America. Takhtajania includes a single species, T. perrieri, endemic only to Madagascar.
The Canellaceae are a family of flowering plants in the order Canellales. The order includes only one other family, the Winteraceae. Canellaceae is native to the Afrotropical and Neotropical realms. They are small to medium trees, rarely shrubs, evergreen and aromatic. The flowers and fruit are often red.
Pilgerodendron is a genus of conifer belonging to the cypress family Cupressaceae. It has only one species, Pilgerodendron uviferum, which is endemic to the Valdivian temperate rain forests and Magellanic subpolar forests of southern Chile and southwestern Argentina. It grows from 40 to 55°S in Tierra del Fuego, where it is the southernmost conifer in the world. It is a member of subfamily Callitroideae, a group of distinct Southern Hemisphere genera associated with the Antarctic flora.
Tasmannia is a genus of woody, evergreen flowering plants of the family Winteraceae. The 40 species of Tasmannia are native to Australia, New Guinea, Sulawesi, Borneo, and the Philippines. The Winteraceae are magnoliids, and are associated with the humid Antarctic flora of the Southern Hemisphere. The members of the family generally have aromatic bark and leaves, and some are used to extract essential oils. The peppery-flavored fruits and leaves of this genus are increasingly used as a condiment in Australia. The peppery flavour can be attributed to polygodial.
Ugni is a genus of plants in the myrtle family Myrtaceae, described as a genus in 1848. It is native to western Latin America from the Valdivian temperate rain forests of southern Chile and adjacent regions of southern Argentina, north to southern Mexico.
Libertia is a genus of monocotyledenous plants in the family Iridaceae, first described as a genus in 1824. It is native to South America, Australia, New Guinea, and New Zealand. Seven species are endemic to New Zealand.
Archipiélago de Juan Fernández National Park is a national park located in the Pacific Ocean 665 kilometres west of Chile's mainland port of San Antonio, in the Juan Fernández Archipelago. The park covers 96 square kilometres and comprises the Santa Clara, Alejandro Selkirk and the most part of the Robinson Crusoe Island islands.
Drimys winteri is a slender tree, growing up to 20 m (66 ft) tall. It is native to the Magellanic and Valdivian temperate rain forests of Chile and Argentina, where it is a dominant tree in the coastal evergreen forests. It is found below 1,200 m (3,937 ft) between latitude 32° south and Cape Horn at latitude 56°. In its southernmost natural range it can tolerate temperatures down to −20 °C (−4 °F).
Uncinia is a genus of flowering plants in the family Cyperaceae, known as hook-sedges in Australia and as hook grasses or bastard grasses in New Zealand. The genus is characterised by the presence of a long hook formed by an extension of the rachilla, which is used to attach the fruit to passing animals (epizoochory), especially birds, and it is this feature which gives the genus its name, from the Latin uncinus, meaning a hook or barb.
The Antarctic Floristic Kingdom, also the Holantarctic Kingdom, is a floristic kingdom that includes most areas of the world south of 40°S latitude. It was first identified by botanist Ronald Good, and later by Armen Takhtajan. The Antarctic Floristic Kingdom is a classification in phytogeography, different from the Antarctic realm classification in biogeography, and from Antarctic flora genera/species classifications in botany.
Polypogon is a nearly cosmopolitan genus of plants in the grass family, commonly known beard grass or rabbitsfoot grass.
Piptochaetium, or speargrass, is a genus of New World plants in the grass family, native to North and South America. Piptochaetium is a bunchgrass genus in the tribe Stipeae.
Tasmannia purpurascens, commonly known as the broad-leaved pepperbush or purple pepperbush is a shrub in the primitive family Winteraceae and is only found growing in the Barrington Tops and Ben Halls Gap regions of New South Wales. It is locally abundant in a restricted subalpine habitat with a high rainfall, often growing in the ecotone in association with Antarctic Beech.
Gamochaeta is a genus of flowering plants in the aster family. There has not always been agreement among botanists regarding its status as a recognized genus, but it has become more accepted in recent years. It currently includes many plants that previously belonged in genus Gnaphalium. Like many species of Gnaphalium, many Gamochaeta are called cudweeds or everlastings.
Yendegaia National Park is located in Tierra del Fuego in the Magallanes y la Antártica Chilena Region of Chile and contains 150,612 ha of mountainous terrain and Valdivian temperate rain forest. It borders the Alberto de Agostini National Park and Tierra del Fuego National Park.
The Bosque Andino Patagónico is a type of temperate to cold forest located in southern Chile and western Patagonia in Chile and Argentina at the southern end of South America. The climate here is influenced by humid air masses moving in from the Pacific Ocean which lose most of their moisture as they rise over the Andes. The flora is dominated by trees, usually of the genus Nothofagus.
