Trees Of New Zealand
New Zealand's long geological isolation means that most of Flora of New Zealand, its flora is unique, with many durable hard woods. There is a wide variety of native trees, adapted to all the various micro-climates in New Zealand. The native bush (forest) ranges from the subtropical Agathis australis, kauri forests of the northern North Island, temperate rainforests of the West Coast, New Zealand, West Coast, the alpine forests of the Southern Alps and Fiordland to the coastal forests of the Abel Tasman National Park and the Catlins. In the early period of British colonisation, many New Zealand trees were known by names derived from the names of unrelated European trees, but more recently the trend has been to adopt the native Māori language names into English. For a listing in order of Māori name, with species names for most, see the ''Flora of New Zealand'' list overnacular names The New Zealand Plant Conservation Network has published a list of New Zealand indigenous vascul ...

Forest Stewart Island
A forest is an ecosystem characterized by a dense ecological community, community of trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a Canopy (biology), canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, ''Global Forest Resources Assessment (FRA), Global Forest Resources Assessment 2020'' found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the largest Terrestrial ecosystem, terrestrial ecosystems of Earth by area, and are found around the globe. 45 percent of forest land is in the Tropical forest, trop ...

Māori Language
Māori (; endonym: 'the Māori language', commonly shortened to ) is an Eastern Polynesian languages, Eastern Polynesian language and the language of the Māori people, the indigenous population of mainland New Zealand. The southernmost member of the Austronesian language family, it is related to Cook Islands Māori, Tuamotuan language, Tuamotuan, and Tahitian language, Tahitian. The Māori Language Act 1987 gave the language recognition as one of New Zealand's official languages. There are regional dialects of the Māori language. Prior to contact with Europeans, Māori lacked a written language or script. Written Māori now uses the Latin script, which was adopted and the spelling standardised by Northern Māori in collaboration with English Protestant clergy in the 19th century. In the second half of the 19th century, European children in rural areas spoke Māori with Māori children. It was common for prominent parents of these children, such as government officials, to us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
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 ...

Dicksoniaceae
Dicksoniaceae is a group of tropical, subtropical and warm temperate ferns, treated as a family in the Pteridophyte Phylogeny Group classification of 2016 (PPG I), and counting 30-40 species. Alternatively, the family may be sunk into a very broadly defined family Cyatheaceae ''sensu lato'' as the subfamily Dicksonioideae. Most of the genera in the family are terrestrial ferns or have very short trunks compared to tree ferns of the family Cyatheaceae ''sensu stricto''. However, some of the larger species can reach several metres in height. A number of others are epiphytes. They are found mostly in tropical regions in the Southern Hemisphere, as far south as southern New Zealand. Larger tree ferns in the genus '' Cibotium'' were formerly included in Dicksoniaceae, but are now segregated as the family Cibotiaceae. Description Species in the family are generally characterized by large pinnate fronds, 1–4 m long. The family includes several species of tree ferns, which grow a singl ...

Alsophila 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] [Amazon] |
Silver Fern
''Alsophila tricolor'', Synonym (taxonomy), synonym ''Cyathea dealbata'', commonly known as the silver fern or silver tree-fern, or as ponga or punga (from Māori language, Māori or ),The Māori word , pronounced , has been borrowed into New Zealand English as a generic term for tree ferns. It is also used to refer to tree fern logs when used for landscaping purposes. English speakers generally pronounce the word . is a species of medium-sized tree fern, endemism, endemic to New Zealand. The fern is usually recognisable by the silver-white colour of the under-surface of mature fronds. It is a symbol commonly associated with the country both overseas and by New Zealanders themselves. ''Alsophila tricolor'' is the correct name for ''Cyathea dealbata'' in ''Alsophila'' because the epithet ''dealbata'' is preoccupied by ''Alsophila dealbata'' C.Presl (now a synonym of ''Sphaeropteris glauca'').

Alsophila Colensoi
''Alsophila colensoi'', also known as the creeping tree fern, mountain tree fern and golden tree fern, is a species of tree fern native to New Zealand, from the southern part of the North Island south to Stewart Island. It grows in submontane to montane forest in damp areas, particularly near the tree line. The trunk is usually prostrate, but may sometimes be erect. It may reach about 1 m in height. Fronds are tripinnate and about 1.5 m long or more. The rachis and stipe are slender, pale brown and are covered with brown scales. Sori occur in two rows, one along each side of the fertile pinnule midvein, and lack indusia. Plants form a thicket with no sign of a trunk. In cultivation, this species requires rich humus, good shade and much moisture. Being a montane plant, it does well in cooler regions. The specific epithet ''colensoi'' commemorates William Colenso William Colenso (17 November 1811 – 10 February 1899) FRS was a Cornish Christian missionary to New Zea ...

Sphaeropteris Medullaris
''Sphaeropteris medullaris'', synonym ''Cyathea medullaris'', commonly known as mamaku or black tree fern, is a large tree fern up to tall. It is distributed across the south-west Pacific from Fiji to Pitcairn Island and is a common plant found in forests of New Zealand. Description The trunk is black and covered with distinctive hexagonal stipe bases. The fronds may be up to long, and arch upwards from the crown. Dead fronds are shed except in very young plants. The primary pinnae are from to long, and the undersides have scales with spines along their margins. As many as 40,000 leaflets have been counted on a single frond. The stipes are thick, black, very rough to the touch, and are similarly covered in black scales with marginal spines. ''Sphaeropteris medullaris'' can be readily distinguished from related species by the hexagonal stipe scars on the trunk, and by the scales with spines on their margins. Fully grown trees can reach a height of , making the species the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Alsophila Cunninghamii
''Alsophila cunninghamii'', synonym ''Cyathea cunninghamii'', also known as the gully tree fern and slender tree fern, is a species of tree fern indigenous to New Zealand including North Island (type locality), South Island and Chatham Islands; also to Victoria, possibly New South Wales, southeastern Queensland and Tasmania in Australia. It grows in damp forest, often emerging from stream gullies and riverbanks. Brownsey noted that it has a lower tolerance for drought than other related species. The erect trunk may be 20 m tall and is usually 6–15 cm in diameter, occasionally as much as 20 cm. Fronds are tri- to tetrapinnate and 3 m or more in length. The rachis and stipe are slender, black brown, warty and covered with brown scales. Sori occur along each side of the pinnule midvein and are covered by hood-like indusia. ''A. cunninghamii'' is an uncommon and slow-growing tree fern. Plants from New Caledonia known as '' Alsophila stelligera'' may represent ...

Tree Fern
Tree ferns are arborescent (tree-like) ferns that grow with a trunk (botany), trunk elevating the fronds above ground level, making them trees. Many extant tree ferns are members of the order Cyatheales, to which belong the families Cyatheaceae (scaly tree ferns), Dicksoniaceae, Metaxyaceae, and Cibotiaceae. It is estimated that Cyatheales originated in the early Jurassic, and is the third group of ferns known to have given rise to tree-like forms. The others are the extinct ''Tempskya'' of uncertain position, and Osmundales where the extinct Guaireaceae and some members of Osmundaceae also grew into trees. In addition there were the Psaroniaceae including ''Tietea'' in the Marattiaceae, Marattiales, which is the sister group to all the leptosporangiate ferns. Other ferns which are also tree ferns, are ''Leptopteris'' and ''Todea'' in the family Osmundaceae, which can achieve short trunks under a metre tall. Osmunda regalis is sometimes considered a tree fern. Fern species with s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Cyatheaceae
The Cyatheaceae are a family of ferns, the scaly tree ferns, one of eight families in the order Cyatheales in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). Alternatively, the family may defined much more broadly (Cyatheaceae '' sensu lato'') as the only family in the Cyatheales, with the PPG I family treated as the subfamily Cyatheoideae. The narrower circumscription is used in this article. The family includes the world's tallest tree ferns, which reach heights up to 20 m. They are also very ancient plants, appearing in the fossil record in the late Jurassic, though the modern genera likely appeared in the Cenozoic. Cyatheaceae are the largest family of tree ferns, including about 640 species. Cyatheaceae and Dicksoniaceae, together with Metaxyaceae and Cibotiaceae, do not form a strongly supported monophyletic group and could be paraphyletic, but several individual subgroups are well supported as being monophyletic.
