Pseudopanax Simplex
''Raukaua simplex'', commonly known as haumakāroa, is a species of evergreen plant in the Araliaceae family. This species is native to New Zealand. The species occurs in certain lowland, montane and subalpine forests from the Waihou River southward to Stewart Island and the Auckland Islands. An example occurrence in Westland forests includes associates such as '' Cyathea smithii'' and ''Dicksonia squarrosa''. Description ''Raukaua simplex'' grows as a shrub to small tree up to 8m in height. The species exhibits a significant change in appearance (heteroblasty) between its juvenile and adult form. Juvenile leaves are palmately compound, 3-5 leaflets, and deeply lobed. Adult leaves are simple, with toothed margins. Taxonomy ''Raukaua simplex'' was first described in 1786 by Georg Forster as ''Panax simplex'' in ''Florulae Insularum Australium Prodromus''. Forster, J.G.A. (1786Florulae Insularum Australium Prodromus 75./ref> In 1997, Mitchell, Frodin and Heads redescribed it, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walter Hood Fitch
Walter Hood Fitch (28 February 1817 – 14 January 1892) was a botanical illustrator, born in Glasgow, Scotland, who executed some 10,000 drawings for various publications. His work in colour lithograph, including 2700 illustrations for ''Curtis's Botanical Magazine'', produced up to 200 plates per year. Biography Fitch was involved in fabric printing from the age of 17 and took to botanical art after meeting William Jackson Hooker, Regius Professor of Botany, a competent botanical illustrator, and the editor of ''Curtis's Botanical Magazine''. Fitch's first lithograph of ''Mimulus roseus'' appeared in the Botanical Magazine in 1834, and he soon became its sole artist. In 1841 W.J. Hooker became director of Royal Botanic Gardens, Kew and Fitch moved to London. After 1841 Fitch was the sole artist for all official and unofficial publications issued by Kew; his work was paid for by Hooker personally. It was not unusual for him to work on several different publications simulta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stewart Island
Stewart Island (, ' glowing skies', officially Stewart Island / Rakiura, formerly New Leinster) is New Zealand's third-largest island, located south of the South Island, across Foveaux Strait. It is a roughly triangular island with a land area of . Its coastline is indented by Paterson Inlet (east), Port Pegasus (south), and Mason Bay (west). The island is generally hilly (rising to at Mount Anglem) and densely forested. Flightless birds, including penguins, thrive because there are few introduced predators. Almost all the island is owned by the New Zealand government, and over 80 percent of the island forms Rakiura National Park. Stewart Island's economy depends on fishing and summer tourism. Its permanent population was recorded at 408 people in the 2018 census. Most residents live in the settlement of Oban on the eastern side of the island. Ferries connect Oban to Bluff in the South Island. Stewart Island is part of the Southland District for local government p ...

Flora Of New Zealand
This article relates to the flora of New Zealand, especially indigenous strains. New Zealand's geographical isolation has meant the country has developed a unique variety of native flora. However, human migration has led to the importation of many other plants (generally referred to as 'exotics' in New Zealand) as well as widespread damage to the indigenous flora, especially after the advent of European colonisation, due to the combined efforts of farmers and specialised societies dedicated to importing European plants & animals. Characteristics Indigenous New Zealand flora generally has the following characteristics: * the majority are evergreen. * few annual herbs. * few cold-tolerant trees. * majority are dispersed by birds. * very few have defences against mammalian browsers. * few nitrogen fixing plants. * few fire-adapted species. * many dioecious species. * flowers are typically small and white. * many plants have divaricating growth forms. * many plants have evolv ...

Vegetation
Vegetation is an assemblage of plants and the ground cover they provide. It is a general term, without specific reference to particular Taxon, taxa, life forms, structure, Spatial ecology, spatial extent, or any other specific Botany, botanical or geographic characteristics. It is broader than the term ''Flora (plants), flora'' which refers to species richness, species composition. Perhaps the closest synonym is ''plant community'', but "vegetation" can, and often does, refer to a wider range of spatial scales than that term does, including scales as large as the global. Primeval redwood forests, coastal mangrove stands, sphagnum bogs, desert soil crusts, Road verge, roadside weed patches, wheat fields, cultivated gardens and lawns; all are encompassed by the term "vegetation". The vegetation type is defined by characteristic dominant species, or a common aspect of the assemblage, such as an elevation range or environmental commonality. The contemporary use of "vegetation" app ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raukaua
''Raukaua'' is a genus of flowering plants in the family Araliaceae. It has an austral distribution, being indigenous to southern Argentina and Chile, as well as New Zealand and the island of Tasmania.David J. Mabberley. 2008. ''Mabberley's Plant-Book'' third edition (2008). Cambridge University Press: UK. . (See ''External links'' below). ''Raukaua'' is a genus of woody plants. They vary in habit: for example ''R. laetevirens'' is a small tree, while ''R. valdiviensis'' is a liana. Like most of Araliaceae, they have palmately compound leaves. The leaves are heteroblastic, that is, conspicuously different in form from juvenile to adult. ''R. simplex'' often produces root suckers and on these, the further the sucker is from the main shoot, the more juvenile the form of the leaves. The Māori extracted an aromatic oil from the leaves of ''R. edgerleyi''. The essential oils of the New Zealand species have been the subject of a phytochemical analysis.Roderick J. Weston. 2004. ...

Heteroblasty
Heteroblasty is the significant and abrupt change in form and function, that occurs over the lifespan of certain plants. Characteristics affected include internode length and stem structure as well as leaf form, size and arrangement. It should not be confused with seasonal heterophylly, where early and late growth in a season are visibly different. This change is different from a homoblastic change which is a gradual change or little change at all, so that there is little difference between the juvenile and adult stages. Some characteristics affected by heteroblastic change include the distance between successive leaves (internode length) and stem structure as well as leaf form, size and arrangement. Heteroblasty is found in many plant families as well as only some species within a genus. This random spread of heteroblastic plants across species is believed to be caused by convergent evolution. The earlier and later stages of development are commonly labeled as juvenile and adult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dicksonia Squarrosa
''Dicksonia squarrosa'', the New Zealand tree fern, whekī or rough tree fern, is a common tree fern endemic to New Zealand. It has a slender black trunk that is usually surrounded by many dead brown fronds. Description This species has a fast growth rate of up to a year, growing to about tall. It produces few fronds, all of which sprout in almost horizontal fashion. The fronds reach in length, much smaller than '' Cyathea'' varieties, and are quite crisp to touch. They form a small "umbrella" on top of the trunk. They are sometimes found sprouting from apparently dead pieces of trunk. The trunks are often used for fencing or edging and fronds will sometimes sprout from the side if the top is dead. A feature of the whekī is the spreading underground rhizomes which can create dense groves, making it one of the most common tree ferns in New Zealand forests. The Latin specific epithet ''squarrosa'' means "with curving ends" (referring to the fronds). Human use The whekī is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyathea Smithii
''Alsophila smithii'', synonym ''Cyathea smithii'', commonly known as the soft tree fern or kātote, is a species of tree fern from New Zealand. Distribution and ecology The species' natural distribution covers all major islands of New Zealand: the North and South Islands, Stewart Island / Rakiura, the Chatham Islands, and south to the Auckland Islands. It is common in montane forest, with populations from the southern regions of its range growing in lowland forest. In the Westland forests of South Island, ''A. smithii'' occurs in the understory of certain broadleaf/podocarp forests. Description ''A. smithii'' is an understory tree fern that grows up to 8 m tall but tends not reaching into the canopy as do other iconic members of this genus. It grows slowly and is not a strong competitor except at higher altitudes. Like related tree ferns, it has rough scales along its rachis and trunk. A distinctive feature is the retention of dead fronds as a skirt. The skirt is no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West Coast Region
The West Coast () is a region of New Zealand on the west coast of the South Island. It is administered by the West Coast Regional Council, and is known co-officially as Te Tai Poutini. It comprises the territorial authorities of Buller District, Grey District and Westland District. The principal towns are Westport, Greymouth and Hokitika. The region, one of the more remote areas of the country, is also the most sparsely populated. With a population of just 32,900 people, the West Coast is the least populous region in New Zealand. The population in the region grew by 0.4% over the year to July 2023. The region has a rich and important history. The land itself is ancient, stretching back to the Carboniferous period; this is evident by the amount of carboniferous materials naturally found there, especially coal. First settled by Kāi Tahu in approximately 1200 AD, the area was famous across New Zealand for its richness in pounamu greenstone. Kāi Tahu traded millions of modern ...

Auckland Islands
The Auckland Islands ( Māori: ''Motu Maha'' "Many islands" or ''Maungahuka'' "Snowy mountains") are an archipelago of New Zealand, lying south of the South Island. The main Auckland Island, occupying , is surrounded by smaller Adams Island, Enderby Island, Disappointment Island, Ewing Island, Rose Island, Dundas Island, and Green Island, with a combined area of . The islands have no permanent human inhabitants. The islands are listed with the New Zealand Outlying Islands. The islands are an immediate part of New Zealand, but not part of any region or district, but instead ''Area Outside Territorial Authority'', like all the other outlying islands except the Solander Islands. Ecologically, the Auckland Islands form part of the Antipodes Subantarctic Islands tundra ecoregion. Along with other New Zealand Subantarctic Islands, they were designated a UNESCO World Heritage Site in 1998. Geography The Auckland Islands lie south of Stewart Island, and from the South ...

Waihou River
The Waihou River is located in the northern North Island of New Zealand. Its former name, Thames River, was bestowed by Captain James Cook in November 1769, when he explored of the river from the mouth. An older Māori name was "Wai Kahou Rounga". A 1947 Geographic Board enquiry ruled that the official name would be Waihou. Geography The river flows north for from the Mamaku Ranges past the towns of Putāruru, Te Aroha, Paeroa and Turua, before reaching the Firth of Thames at the south end of the Hauraki Gulf near the town of Thames. In its lower reaches, the river and the nearby Piako River form the wide alluvial Hauraki Plains. Just before the river reaches the ocean, State Highway 25 crosses the river over the Kopu Bridge, which was the longest single lane bridge in the country at and the only remaining swing bridge on a New Zealand state highway. The bridge was infamous for the queues of vehicles travelling to and from the Coromandel Peninsula until a new two lan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Georg Forster
Johann George Adam Forster, also known as Georg Forster (; 27 November 1754 – 10 January 1794), was a German geography, geographer, natural history, naturalist, ethnology, ethnologist, travel literature, travel writer, journalist and revolutionary. At an early age, he accompanied his father, Johann Reinhold Forster, on several scientific expeditions, including James Cook's Second voyage of James Cook, second voyage to the Pacific Ocean, Pacific. His report of that journey, ''A Voyage Round the World'', contributed significantly to the ethnology of the people of Polynesia and remains a respected work. As a result of the report, Forster, who was admitted to the Royal Society at the early age of twenty-two, came to be considered one of the founders of modern scientific travel literature. After returning to continental Europe, Forster turned toward academia. He taught natural history at the Collegium Carolinum (Kassel), Collegium Carolinum in the Ottoneum, Kassel (1778–84), a ...
