Weinmannia Sylvicola
''Weinmannia sylvicola'', known as tōwai or tawhero, is a medium-sized evergreen tree of the family Cunoniaceae native to northern New Zealand. It grows to 15 m or more, with a trunk up to 1 m in diameter. Adult leaves are toothed and leathery, with up to five pairs of leaflets. Juvenile leaves are thinner and have up to ten pairs of leaflets. Flowers are small and pink or white, occurring in 8–12 cm racemes. Fruits are 4–5 cm capsules, which release many tiny seeds that are dispersed by wind. Tōwai occurs in forest and forest margins from North Cape south to the Waitākere Ranges west of Auckland. A closely related tree, kāmahi (''W. racemosa''), replaces tōwai south of latitude 37°S.

Plants Of The World Online
Plants of the World Online (POWO) is an online database published by the Royal Botanic Gardens, Kew. It was launched in March 2017 with the ultimate aim being "to enable users to access information on all the world's known seed-bearing plants by 2020". The initial focus was on tropical African Floras, particularly Flora Zambesiaca, Flora of West Tropical Africa and Flora of Tropical East Africa. The database uses the same taxonomical source as Kew's World Checklist of Selected Plant Families, which is the International Plant Names Index, and the World Checklist of Vascular Plants (WCVP). POWO contains 1,234,000 global plant names and 367,600 images. See also *Australian Plant Name Index *Convention on Biological Diversity *World Flora Online *Tropicos Tropicos is an online botanical database containing taxonomic information on plants, mainly from the Neotropical realm (Central, and South America).

Seed Dispersal
In Spermatophyte plants, seed dispersal is the movement, spread or transport of seeds away from the parent plant. Plants have limited mobility and rely upon a variety of dispersal vectors to transport their seeds, including both abiotic vectors, such as the wind, and living ( biotic) vectors such as birds. Seeds can be dispersed away from the parent plant individually or collectively, as well as dispersed in both space and time. The patterns of seed dispersal are determined in large part by the dispersal mechanism and this has important implications for the demographic and genetic structure of plant populations, as well as migration patterns and species interactions. There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus. These modes are typically inferred based on adaptations, such as wings or fleshy fruit. However, this simplified view may ignor ...

Trees Of New Zealand
New Zealand's long geological isolation means that most of 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 kauri forests of the northern North Island, temperate rainforests of the West Coast, the alpine forests of the Southern Alps / Kā Tiritiri o te Moana 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 vascular plants including all 574 native tr ...

37th Parallel South
The 37th parallel south is a circle of latitude that is 37 degrees south of the Earth's equatorial plane. It crosses the Atlantic Ocean, the Indian Ocean, Australasia, the Pacific Ocean and South America. This parallel approximates that latitude at which solar irradiance equals the planetary average,See Nadeau, Alice and McGhee, Richard; ‘A simple formula for a planet’s mean annual insolation by latitude’; ''Icarus'', volume 291, 15 July 2017, pp. 46-50 with higher insolation equatorward and lower poleward. An exploration of the 37th parallel south is the theme of Jules Verne's novel ''In Search of the Castaways''. The phantom reef of Maria Theresa Reef is supposed to lie on this parallel in the Pacific Ocean.

Weinmannia Racemosa
''Weinmannia racemosa'', commonly called kāmahi, is an evergreen small shrub to medium-sized tree of the family Cunoniaceae. It is the most abundant forest tree in New Zealand, occurring in lowland, montane, and subalpine forests and shrubland from the central North Island south to Stewart Island. Description Kāmahi bears racemes of small, pink or white flowers from July to January. Fruits are small capsules, long, ripening from October to May. Kāmahi generally occurs with other broadleaf trees, at times acting as a pioneer species which is eventually succeeded by the southern beeches (''Nothofagus'' spp.) or podocarps. It reaches or more in the Catlins of the south-eastern South Island. In forests to the west of the Southern Alps it codominates with southern rātā (''Metrosideros umbellata'') and black beech (''N. solandri''). A closely related tree, tōwai or tawhero ('' W. sylvicola''), replaces kāmahi in the North Island north of latitude 38°S. Uses The bark is ...

Waitākere Ranges
The Waitākere Ranges is a mountain range in New Zealand. Located in West Auckland between metropolitan Auckland and the Tasman Sea, the ranges and its foothills and coasts comprise some of public and private land. The area, traditionally known to Māori as ''Te Wao Nui o Tiriwa'' (The Great Forest of Tiriwa), is of local, regional, and national significance. The Waitākere Ranges includes a chain of hills in the Auckland Region, generally running approximately from north to south, 25 km west of central Auckland. The ranges are part of the Waitākere Ranges Regional Park. From 1 May 2018 the forested areas of the Waitākere Ranges Regional Park were closed, with some exceptions, while Auckland Council upgraded the tracks to dry foot standard protect the roots and to prevent the spread of kauri dieback, bacteria that affect kauri trees and prevents them from getting nutrients, effectively killing them.

North Cape, New Zealand
North Cape () is the northernmost point of New Zealand's main islands. At the northeastern tip of the Aupouri Peninsula, the cape lies east and north of Cape Reinga. The name ''North Cape'' is sometimes used to refer just to the cape that is known in Māori as and which overlooks Murimotu Island, and sometimes just to the eastern point of Murimotu Island. It is also used to refer to the whole larger headland stretching about five kilometres from Murimotu Island westwards to Kerr Point and including the Surville Cliffs. Statistics New Zealand uses a statistical area called North Cape for population data, extending south down the Aupouri Peninsula to the Houhora Heads. North Cape, one of the four New Zealand Cardinal Capes,Chart Of New Zealand – J Cook 1769–7 Retrieved on 7 December 2017. was named by James Cook, Commander of ''Endeavour'' in its 1769–1770 voyage.

Seed
A seed is an embryonic plant enclosed in a protective outer covering, along with a food reserve. The formation of the seed is a part of the process of reproduction in seed plants, the spermatophytes, including the gymnosperm and angiosperm plants. Seeds are the product of the ripened ovule, after the embryo sac is fertilized by sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote, and grows within the mother plant to a certain size before growth is halted. The seed coat arises from the integuments of the ovule. Seeds have been an important development in the reproduction and success of vegetable gymnosperm and angiosperm plants, relative to more primitive plants such as ferns, mosses and liverworts, which do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological niches on land, from forests to grasslands both in hot and cold climates. The term "seed" also has a general me ...

Tree
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Capsule (botany)
In botany a capsule is a type of simple, dry, though rarely fleshy dehiscent fruit produced by many species of angiosperms (flowering plants). Origins and structure The capsule (Latin: ''capsula'', small box) is derived from a compound (multicarpeled) ovary. A capsule is a structure composed of two or more carpels. In (flowering plants), the term locule (or cell) is used to refer to a chamber within the fruit. Depending on the number of locules in the ovary, fruit can be classified as uni-locular (unilocular), bi-locular, tri-locular or multi-locular. The number of locules present in a gynoecium may be equal to or less than the number of carpels. The locules contain the ovules or seeds and are separated by septa. Dehiscence In most cases the capsule is dehiscent, i.e. at maturity, it splits apart (dehisces) to release the seeds within. A few capsules are indehiscent, for example those of ''Adansonia digitata'', ''Alphitonia'', and '' Merciera''. Capsules are often classifie ...

Fruit
In botany, a fruit is the seed-bearing structure in flowering plants that is formed from the ovary after flowering. Fruits are the means by which flowering plants (also known as angiosperms) disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; in fact, humans and many animals have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings. In common language usage, "fruit" normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet or sour and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term "fruit" also i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
