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 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.
Alsophila tricolor, synonym Cyathea dealbata, commonly known as the silver fern or silver tree-fern, or as ponga or punga, is a species of medium-sized tree fern, 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.
Sphaeropteris medullaris, synonym Cyathea medullaris, commonly known as mamaku or black tree fern, is a large tree fern up to 20 m tall. It is distributed across the south-west Pacific from Fiji to Pitcairn Island. Its other Māori names include katātā, kōrau, or pītau.
Lake Matheson is a small glacial lake in South Westland, New Zealand, near the township of Fox Glacier. It was a traditional food-gathering place for local Māori. An easy walking track circles the lake, which is famous for its reflected views of Aoraki / Mount Cook and Mount Tasman.
Aciphylla is a genus of about 40 species of herbaceous plants in the family Apiaceae, all but two of them endemic to New Zealand. They range from small cushion plants to tall flower spikes surrounded by rosettes of stiff, pointed leaves, the latter probably adaptations to prevent browsing by moa. Their common name is speargrass or Spaniard. Most Aciphylla species live in subalpine or alpine habitats in the South Island. Fragrant oil extracted from some large species, known as taramea, is still used as a perfume by Māori.
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.
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.
The Hymenophyllaceae, the filmy ferns and bristle ferns, are a family of two to nine genera and about 650 known species of ferns, with a subcosmopolitan distribution, but generally restricted to very damp places or to locations where they are wetted by spray from waterfalls or springs. A recent fossil find shows that ferns of Hymenophyllaceae have existed since at least the Upper Triassic.
Alsophila smithii, synonym Cyathea smithii, commonly known as the soft tree fern or kātote, is a species of tree fern from New Zealand.
Nothofagus menziesii, commonly known as silver beech, is a tree of the southern beech family endemic to New Zealand. Its common name probably comes from the fact that its bark is whitish in colour, particularly in younger specimens. It is found from Thames southwards in the North Island, and throughout the South Island. Silver beech is a forest tree up to 30 m tall. The trunk, which is often buttressed, may be up to 2 m in diameter. The leaves are small, thick and almost round in shape, 6 to 15 mm long and 5 to 15 mm wide with rounded teeth which usually occur in pairs, 1 or 2 hair fringed domatia are found on the underside of each leaf. Its Māori name is tawhai. It grows from low altitudes to the mountains. Nothofagus menziesii was proposed to be renamed Lophozonia menziesii in 2013.
Hymenophyllum nephrophyllum, the kidney fern, is a filmy fern species native to New Zealand. It commonly grows on the forest floor of open native bush. Individual kidney-shaped fronds stand about 5–10 cm tall. In hot weather they shrivel up to conserve moisture, but open up again when the wet returns. This species has very thin fronds which are only four to six cells in thickness. In the Māori language they are also called raurenga.
Cranfillia fluviatilis, synonym Blechnum fluviatile, is a fern known in the Māori language as kiwikiwi. A herbaceous plant, C. fluviatilis is a "hard fern" of the genus Cranfillia in the family Blechnaceae. It was identified by Patrick Brownsey in 1979. Other common names are star fern, creek fern, kawakawa and kiwakiwa.
The geology of New Zealand is noted for its volcanic activity, earthquakes and geothermal areas because of its position on the boundary of the Australian Plate and Pacific Plates. New Zealand is part of Zealandia, a microcontinent nearly half the size of Australia that broke away from the Gondwanan supercontinent about 83 million years ago. New Zealand's early separation from other landmasses and subsequent evolution have created a unique fossil record and modern ecology.
Ascarina lucida, commonly known as hutu is a species of small tree in the family Chloranthaceae. It is endemic to New Zealand, being common on the West Coast and Nelson regions of the South Island and more rarely found in the North Island. A typical plant association is within the Westland podocarp/broadleaf forests with common understory associates of Blechnum discolor, Pseudowintera colorata, Neopanax colensoi and Coprosma lucida. Most genus members are dioecious, producing unisexual male or female flowers on separate plants. Ascarina lucida, the only member of its genus to occur in New Zealand, is monoecious. It will grow to a height of 6m and can have a 30 cm trunk. The leaves which are in opposite pairs are simple, yellowish green in color, have a raised mid rib and are very similar to Laurelia novae-zelandiae. Their margins have prominent teeth which are dark colored at the tips. Ascarina lucida is now nearly extinct in the Taranaki region but was last reported in Oct 1969 at Mt Taranaki, near Pukeiti by Colin Ogle.
Gleichenia microphylla is a small fern growing in Australia and New Zealand.
Polystichum vestitum, commonly known as the prickly shield fern or pūnui (Maori), is a hardy, evergreen or semi-evergreen ground fern.
Leptopteris hymenophylloides, which is commonly called single crepe fern is a fern in the family Osmundaceae.
Dicksonia lanata is a fern endemic to New Zealand. Colloquial names include stumpy tree fern, tūākura and tūōkura.
Asplenium hookerianum, commonly known as Hooker's spleenwort, rocklax and maidenhair fern, is a small fern native to New Zealand and Australia.
Hymenophyllum rarum, the narrow filmy-fern, is a species of fern from the family Hymenophyllaceae. This thin-leaved fern is commonly found in New Zealand and Tasmania, growing in patches on rocks and is epiphytic on trees and tree ferns, growing in moist gullies or rainforests. A rather drought tolerant species often found at exposed sites ranging from coastal to montane areas. Forming extensive, interwoven and creeping patches with its thin long (creeping) rhizomes sparsely covered in red-brown hairs, easily recognised by its membranous grey-green fronds, the smooth margins of the pinnae, ultimate segments and indusia; and by the sunken sori in the uppermost segments of the uppermost pinnae. The species can be found throughout Tasmanian rainforests as well as occurring in New South Wales, Victoria and New Zealand on the North and South Islands as well as, Stewart, Chatham and Auckland Islands.
