Maple
''Acer'' () is a genus of trees and shrubs commonly known as maples. The genus is placed in the family Sapindaceae.Stevens, P. F. (2001 onwards). Angiosperm Phylogeny Website. Version 9, June 2008 nd more or less continuously updated since http://www.mobot.org/MOBOT/research/APweb/. There are approximately 132 species, most of which are native to Asia, with a number also appearing in Europe, northern Africa, and North America. Only one species, ''Acer laurinum'', extends to the Southern Hemisphere.Gibbs, D. & Chen, Y. (2009The Red List of Maples Botanic Gardens Conservation International (BGCI) The type species of the genus is the sycamore maple, ''Acer pseudoplatanus'', the most common maple species in Europe.van Gelderen, C. J. & van Gelderen, D. M. (1999). ''Maples for Gardens: A Color Encyclopedia'' Maples usually have easily recognizable palmate leaves (''Acer negundo'' is an exception) and distinctive winged fruits.

Maple Syrup
Maple syrup is a syrup made from the sap of maple trees. In cold climates, these trees store starch in their trunks and roots before winter; the starch is then converted to sugar that rises in the sap in late winter and early spring. Maple trees are tapped by drilling holes into their trunks and collecting the sap, which is processed by heating to evaporate much of the water, leaving the concentrated syrup. Maple syrup was first made by the Indigenous peoples of North America. The practice was adopted by European settlers, who gradually changed production methods. Technological improvements in the 1970s further refined syrup processing. Virtually all of the world's maple syrup is produced in Canada and the United States. The Canadian province of Quebec is the largest producer, responsible for 70 percent of the world's output; Canadian exports of maple syrup in 2016 were C$487 million (about US$360 million), with Quebec accounting for some 90 percent of this total.

Acer Saccharum
''Acer saccharum'', the sugar maple, is a species of flowering plant in the soapberry and lychee family Sapindaceae. It is native to the hardwood forests of eastern Canada and eastern United States. Sugar maple is best known for being the primary source of maple syrup and for its brightly colored fall foliage. It may also be known as "rock maple", "sugar tree", "birds-eye maple", "sweet maple", "curly maple", or "hard maple", particularly when referring to the wood. Description ''Acer saccharum'' is a deciduous tree normally reaching heights of , and exceptionally up to . A 10-year-old tree is typically about tall. As with most trees, forest-grown sugar maples form a much taller trunk and narrower canopy than open-growth ones. The leaves are deciduous, up to long and wide, palmate, with five lobes and borne in opposite pairs. The basal lobes are relatively small, while the upper lobes are larger and deeply notched. In contrast with the angular notching of the silver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Acer Negundo
''Acer negundo'', the box elder, boxelder maple, Manitoba maple or ash-leaved maple, is a species of maple native to North America. It is a fast-growing, short-lived tree with opposite, compound leaves. It is sometimes considered a weedy or invasive species, and has been introduced to and naturalized throughout much of the world, including in South America, Australia, New Zealand, South Africa, much of Europe, and parts of Asia. Description ''Acer negundo'' is a fast-growing and fairly short-lived tree that grows up to tall, with a trunk diameter of , rarely up to diameter. It often has several trunks and can form impenetrable thickets.van Gelderen, C.J. & van Gelderen, D.M. (1999). ''Maples for Gardens: A Color Encyclopedia''. The typical lifespan of box elder is 60 - 75 years. Under exceptionally favorable conditions, it may live to 100 years. The shoots are green, often with a whitish to pink or violet waxy coating when young. Branches are smooth, somewhat brittle, and ...

Acer Pseudoplatanus
''Acer pseudoplatanus'', known as the sycamore in the British Isles and as the sycamore maple in the United States, is a species of flowering plant in the soapberry and lychee family Sapindaceae. It is a large deciduous, broad-leaved tree, tolerant of wind and coastal exposure. It is native to Central Europe and Western Asia, from France eastward to Ukraine, northern Turkey and the Caucasus and southward in the mountains of Italy and northern Iberia. The sycamore establishes itself easily from seed and was introduced to the British Isles by 1500. It is now naturalised there and in other parts of Europe, North America, Australia and New Zealand, where it may become an invasive species. The sycamore can grow to a height of about and the branches form a broad, rounded crown. The bark is grey, smooth when young and later flaking in irregular patches. The leaves grow on long leafstalks and are large and palmate, with five large radiating lobes. The flowers are greenish-yellow ...

Autumn Leaf Colour
Autumn leaf color is a phenomenon that affects the normal green leaves of many deciduous trees and shrubs by which they take on, during a few weeks in the autumn season, various shades of yellow, orange, red, purple, and brown. The phenomenon is commonly called autumn colours or autumn foliage in British English and fall colors, fall foliage, or simply foliage in American English. In some areas of Canada and the United States, " leaf peeping" tourism is a major contribution to economic activity. This tourist activity occurs between the beginning of color changes and the onset of leaf fall, usually around September and October in the Northern Hemisphere and April to May in the Southern Hemisphere. Chlorophyll and the green/yellow/orange colors A green leaf is green because of the presence of a pigment known as chlorophyll, which is inside an organelle called a chloroplast. When abundant in the leaf's cells, as during the growing season, the chlorophyll's green color domin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 typicall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sapindaceae
The Sapindaceae are a family of flowering plants in the order Sapindales known as the soapberry family. It contains 138 genera and 1858 accepted species. Examples include horse chestnut, maples, ackee and lychee. The Sapindaceae occur in temperate to tropical regions, many in laurel forest habitat, throughout the world. Many are laticiferous, i.e. they contain latex, a milky sap, and many contain mildly toxic saponins with soap-like qualities in either the foliage and/or the seeds, or roots. The largest genera are '' Serjania'', ''Paullinia'', '' Allophylus'' and '' Acer''. Description Plants of this family have a variety of habits, from trees to herbaceous plants to lianas. The leaves of the tropical genera are usually spirally alternate, while those of the temperate maples ('' Acer), Aesculus'', and a few other genera are opposite. They are most often pinnately compound, but are palmately compound in ''Aesculus'', and simply palmate in ''Acer''. The petiole has a swol ...

Samara (fruit)
A samara (, ) is a winged achene, a type of fruit in which a flattened wing of fibrous, papery tissue develops from the ovary wall. A samara is a simple dry fruit, and is indehiscent (not opening along a seam). The shape of a samara enables the wind to carry the seed farther away from the tree than regular seeds would go, and is thus a form of anemochory. In some cases the seed is in the centre of the wing, as in the elms (genus ''Ulmus''), the hoptree (''Ptelea trifoliata''), and the bushwillows (genus '' Combretum''). In other cases the seed is on one side, with the wing extending to the other side, making the seed autorotate as it falls, as in the maples (genus '' Acer'') and ash trees (genus '' Fraxinus''). There are also single-wing samara such as mahogany (genus Swietenia) which have a shape that enables fluttering. Some species that normally produce paired samaras, such as '' Acer pseudoplatanus'', can also produce them in groups of three or four. File:TripleS ...

Dipteronia
''Dipteronia'' is a genus with two living and one extinct species in the soapberry family Sapindaceae. The living species are native to central and southern China, The fossil species has been found in Middle Paleocene to Early Oligocene sediments of North America and China. Classification Older classifications segregated the maples (''Acer'') and ''Dipteronia'' into the family Aceraceae, however work by the Angiosperm Phylogeny Group ( APG I onward) and related investigations led to the subsuming of Acereae into Sapindaceae as the tribe Acereae. ''Dipteronia'' is considered to be the sister genus to ''Acer.'' Description They are deciduous flowering shrubs or small trees, reaching tall. The leaf arrangement is opposite and pinnate with between 7 - 15 leaflets to each leaf. The inflorescences are paniculate, terminal or axillary. The flowers have five sepals and petals; staminate flowers have eight stamens, and bisexual flowers have a two-celled ovary. The fruit is a rounded ...
