Pleurophyllum is a genus of subantarctic plants in the tribe Astereae within the family Asteraceae. [3]
Pleurophyllum is native to the subantarctic islands of New Zealand (the Auckland Islands, Campbell Island and the Antipodes Islands) and Australia (Macquarie Island).
The Auckland Islands are an archipelago of New Zealand, lying 465 kilometres (290 mi) south of the South Island. The main Auckland Island, occupying 510 km2 (200 sq mi), is surrounded by smaller Adams Island, Enderby Island, Disappointment Island, Ewing Island, Rose Island, Dundas Island, and Green Island, with a combined area of 626 km2 (240 sq mi). The islands have no permanent human inhabitants.
Auckland Island is the main island of the eponymous uninhabited archipelago in the Pacific Ocean. It is part of the New Zealand subantarctic area. It is inscribed in the UNESCO World Heritage list together with the other New Zealand Subantarctic Islands in the region.
Azorella is a genus of flowering plants in the family Apiaceae, native to South America, New Zealand, southeastern Australia, and the islands of the Southern Ocean.
Cordyline is a genus of about 15 species of woody monocotyledonous flowering plants in family Asparagaceae, subfamily Lomandroideae. The subfamily has previously been treated as a separate family Laxmanniaceae, or Lomandraceae. Other authors have placed the genus in the Agavaceae. Cordyline is native to the western Pacific Ocean region, from New Zealand, eastern Australia, southeastern Asia and Polynesia, with one species found in southeastern South America.
Dracophyllum is a genus of plants belonging to the family Ericaceae, formerly Epacridaceae. There are 61 species in the genus, mostly shrubs, but also cushion plants and trees, found in New Zealand, Australia, Lord Howe Island and New Caledonia. The name Dracophyllum, meaning dragon-leaf, refers to their strong outward similarity to the unrelated Dracaena, sometimes known as dragon tree. Although dicotyledonous, they resemble primitive monocots with their slender leaves concentrated in clumps at the ends of the branches; they are sometimes called grass-trees.
Astereae is a tribe of plants in the family Asteraceae that includes annuals, biennials, perennials, subshrubs, shrubs, and trees. Plants within the tribe are present nearly worldwide divided into 170 genera and more than 2,800 species, making it the second-largest tribe in the family behind Senecioneae. They are found primarily in temperate regions of the world.
Olearia lyallii is a New Zealand plant from the genus Olearia. It is commonly known as the subantarctic tree daisy. The species is endemic to the Snares Islands and southern New Zealand, and has also established itself as an introduced species on the Auckland Islands, where the type specimen was described from. O. lyallii forms trees up to 10 m tall with trunks 50 cm in diameter.
Cotula is a genus of flowering plant in the sunflower family. It includes plants known generally as water buttons or buttonweeds.
Rostkovia is a genus of plant in family Juncaceae described as a genus in 1809.
The Auckland Island pig is a feral landrace of domestic pig found on subantarctic Auckland Island, New Zealand. Its ancestors have inhabited the island since 1807, and, as an invasive species, has had a considerable environmental impact.
Pleurophyllum speciosum, also known as the giant emperor daisy or Campbell Island daisy, is a megaherb native to the Auckland and Campbell Islands of New Zealand. A false colour image is depicted on the lower left corner on the reverse of the current five dollar New Zealand banknote. The Campbell Island daisy was first described by Joseph Dalton Hooker in Flora Antarctica of 1844, after he had collected it during the Ross expedition.
Damnamenia is a genus of flowering plants in the family Asteraceae.
Pleurophyllum hookeri, also known as the silver-leaf daisy or sage-green rosette herb, is a herbaceous plant in the family Asteraceae, a megaherb native to the subantarctic Auckland and Campbell Islands of New Zealand and Australia’s Macquarie Island. It grows up to 900 mm in height and has crimson button flowers and long, silky, silver leaves, with a large carrot-like tuber and long roots. It also has the unusual feature of a vertically contractile stem, most of which is underground, which serves to keep the leaf rosette close to the ground surface and the plant anchored securely against the very strong winds typical of subantarctic islands. Prior to the successful eradication of introduced mammals on Macquarie Island in 2011, it had been threatened there by black rats and European rabbits.
Poa foliosa is a species of tussock grass commonly known as muttonbird poa. It is native to the subantarctic islands of New Zealand and Australia.
Pleurophyllum criniferum is a species of flowering plant in the family Asteraceae that is endemic to the subantarctic islands of New Zealand.
Phenacoleachiidae is a family of scale insects commonly known as the phenacoleachiids. They are found only in the South Island of New Zealand, and on certain offshore islands. There are two species in a single genus.
Myosotis antarctica is a species of flowering plant in the family Boraginaceae, native to Campbell Island of New Zealand and southern Chile. Joseph Dalton Hooker described the species in his 19th century work Flora Antarctica. Plants of this species of forget-me-not are perennial and have white or blue corollas. It is one of two native species of Myosotis in the New Zealand subantarctic islands, the other being M. capitata, which also has blue corollas.
Megaherbs are a group of herbaceous wildflowers growing in the New Zealand subantarctic islands and on the other 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. They suffer from overgrazing due to introduced mammals.
Ichneutica erebia is a moth of the family Noctuidae. This species is endemic to New Zealand and is found on Campbell Island and the Auckland Islands. Adults of this species are on the wing from August to January. The adults are variable in appearance but can be distinguished from similar species by the patters or lack thereof on their forewings. The larvae of I. erebia are polyphagous and hosts include Pleurophyllum criniferum, species within the genera Stilbocarpa and Carex, as well as Chionochloa antarctica', Urtica australis and Raukaua simplex.
Clasmatocolea rigens is a species of liverwort belonging to the family Lophocoleaceae. It is among the most common liverwort species of Kerguelen Island, Crozet Archipelago and Prince Edward Islands but is also found in other subantarctic islands and in South-America.
