Wollemi Pine
''Wollemia'' is a genus of coniferous trees in the family Araucariaceae. It was known only through fossil records until 1994, when the Australian species ''Wollemia nobilis'' was discovered in a temperate rainforest wilderness area of the Wollemi National Park in New South Wales. It was growing in a remote series of narrow, steep-sided, sandstone gorges north-west of Sydney. The genus is named after the National Park. In both botanical and popular literature, the tree has been almost universally referred to as the Wollemi pine (), although it is not a true pine (genus ''Pinus''), nor a member of the pine family (Pinaceae), but is related to ''Agathis'' and ''Araucaria'' in the family Araucariaceae. The Wollemi pine is classified as critically endangered (CR) on the IUCN's Red List, and is legally protected in Australia. After it was discovered that the trees could be successfully cloned, new trees were potted up in the Botanic Gardens of Sydney and Mount Annan. A Recovery Plan ...

Australian Botanic Garden Mount Annan
The Australian Botanic Garden Mount Annan is a botanical garden located in a hilly area of the southwestern Sydney suburb of , between Campbelltown and Camden, New South Wales. It is the largest botanical garden in Australia, specializing in native plants, with a collection of over 4000 species. Officially opened in 1988, it was known as Mount Annan Botanic Garden, until 2011. History and management The traditional custodians of the land now occupied by the gardens were the Dharawal indigenous Australian people. Later, it became dairy pasture land, before the land was acquired by the Royal Botanic Gardens and Domain Trust in 1984 and The garden was opened to the public in 1988 by the Duchess of York, Sarah Ferguson. The gardens are managed by the Botanic Gardens Trust trading the Botanic Gardens & Centennial Parklands, that also has responsibility for the Royal Botanic Gardens, Sydney and the Blue Mountains Botanic Garden at . The trust is a division of the NSW Office of E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pollen
Pollen is a powdery substance produced by seed plants. It consists of pollen grains (highly reduced microgametophytes), which produce male gametes (sperm cells). Pollen grains have a hard coat made of sporopollenin that protects the gametophytes during the process of their movement from the stamens to the pistil of flowering plants, or from the male cone to the female cone of gymnosperms. If pollen lands on a compatible pistil or female cone, it germinates, producing a pollen tube that transfers the sperm to the ovule containing the female gametophyte. Individual pollen grains are small enough to require magnification to see detail. The study of pollen is called palynology and is highly useful in paleoecology, paleontology, archaeology, and forensics. Pollen in plants is used for transferring haploid male genetic material from the anther of a single flower to the stigma of another in cross-pollination. In a case of self-pollination, this process takes place from the anth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Wind Pollination
Anemophily or wind pollination is a form of pollination whereby pollen is distributed by wind. Almost all gymnosperms are anemophilous, as are many plants in the order Poales, including grasses, sedges, and rushes. Other common anemophilous plants are oaks, pecans, pistachios, sweet chestnuts, alders and members of the family Juglandaceae (hickory or walnut family). Approximately 12% of plants across the globe are pollinated by anemophily, including cereal crops like rice and corn and other prominent crop plants like wheat, rye, barley, and oats. In addition, many pines, spruces, and firs are wind-pollinated, and. Syndrome Features of the wind-pollination syndrome include a lack of scent production, a lack of showy floral parts (resulting in small, inconspicuous flowers), reduced production of nectar, and the production of enormous numbers of pollen grains. This distinguishes them from entomophilous and zoophilous species (whose pollen is spread by insects and vertebrates re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ARKive
ARKive was a global initiative with the mission of "promoting the conservation of the world's threatened species, through the power of wildlife imagery", which it did by locating and gathering films, photographs and audio recordings of the world's species into a centralised digital archive. Its priority was the completion of audio-visual profiles for the c. 17,000 species on the IUCN Red List of Threatened Species. The project was an initiative of Wildscreen, a UK-registered educational charity, based in Bristol. The technical platform was created by Hewlett-Packard, as part of the HP Labs' Digital Media Systems research programme. ARKive had the backing of leading conservation organisations, including BirdLife International, Conservation International, International Union for Conservation of Nature (IUCN), the United Nations' World Conservation Monitoring Centre (UNEP-WCMC), and the World Wide Fund for Nature (WWF), as well as leading academic and research institutions, such ...

Leaf
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper (adaxial) and lower ( abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs light ...

Branch
A branch, sometimes called a ramus in botany, is a woody structural member connected to the central trunk (botany), trunk of a tree (or sometimes a shrub). Large branches are known as boughs and small branches are known as twigs. The term ''twig'' usually refers to a wikt:terminus, terminus, while ''bough'' refers only to branches coming directly from the trunk. Due to a broad range of species of trees, branches and twigs can be found in many different shapes and sizes. While branches can be nearly vertical and horizontal, horizontal, vertical, or diagonal, the majority of trees have upwardly diagonal branches. A number of mathematical properties are associated with tree branchings; they are natural examples of fractal patterns in nature, and, as observed by Leonardo da Vinci, their cross section (geometry), cross-sectional areas closely follow the da Vinci branching rule. Terminology Because of the enormous quantity of branches in the world, there are numerous names in Engl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conifer Cone
A conifer cone (in formal botany, botanical usage: strobilus, plural strobili) is a seed-bearing organ on gymnosperm plants. It is usually woody, ovoid to globular, including scales and bracts arranged around a central axis, especially in conifers and cycads. The cone of Pinophyta (conifer clade) contains the plant sexuality, reproductive structures. The woody cone is the female cone, which produces seeds. The male cone, which produces pollen, is usually herbaceous plant, herbaceous and much less conspicuous even at full maturity. The name "cone" derives from Greek ''konos'' (pine cone), which also gave name to the cone (geometry), geometric cone. The individual plates of a cone are known as ''scales''. The ''umbo'' of a conifer cone refers to the first year's growth of a seed scale on the cone, showing up as a protuberance at the end of the two-year-old scale. The male cone (microstrobilus or pollen cone) is structurally similar across all conifers, differing only in small wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coppice
Coppicing is a traditional method of woodland management which exploits the capacity of many species of trees to put out new shoots from their stump or roots if cut down. In a coppiced wood, which is called a copse, young tree stems are repeatedly cut down to near ground level, resulting in a stool. New growth emerges, and after a number of years, the coppiced tree is harvested, and the cycle begins anew. Pollarding is a similar process carried out at a higher level on the tree in order to prevent grazing animals from eating new shoots. ''Daisugi'' (台杉, where ''sugi'' refers to Japanese cedar), is a similar Japanese technique. Many silviculture practices involve cutting and regrowth; coppicing has been of significance in many parts of lowland temperate Europe. The widespread and long-term practice of coppicing as a landscape-scale industry is something that remains of special importance in southern England. Many of the English language terms referenced in this article are pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coco Pops
Cocoa Krispies (also known as Choco Krispis, Choco Krispies, Coco Pops, Choco Pops depending on region) is a breakfast cereal produced by Kellogg's, coming both as a boxed cereal and as a snack bar with a 'dried milk' covered bottom. It is a cocoa flavored version of Rice Krispies that contains real chocolate. In Canada, Rice Krispies Cocoa is their variant of the cereal, with a lighter chocolate flavor. Off-brand "coco krispies" are sold by other companies. The cereal was introduced in the United States in 1958. In 2003, the cereal was renamed "Cocoa Rice Krispies", as Kellogg's endeavored to unite their Rice Krispies variations under a single marketing schema. In 2006, the name was changed back to Cocoa Krispies. Kellogg's has released variations of Cocoa Krispies such as "Cocoa Krispies Cereal Straws", "Cocoa Krispies Choconilla", and Chocos. Other markets The cereal is known as ''Choco Krispis'' in Mexico, the Dominican Republic, El Salvador, Costa Rica, Honduras, C ...
