Liquidambar Formosana
''Liquidambar formosana'', commonly known as the Taiwanese sweet gum or Formosan gum, is a species of tree in the family Altingiaceae native to East Asia. Description ''Liquidambar formosana'' is a large, native, deciduous tree that grows up to 30-40m tall. The leaves are 10~15 cm wide., and are three-lobed unlike five- to seven-lobed leaves of most American ''Liquidambar'' species. The foliage of the ''L. formosana'' turns a very attractive red color in autumn. Leaves grow in an alternate arrangement, and are simple, palmately-veined, with serrated margins. Roots can be aggressive and branches are usually covered with corky projections. The individual flowers of ''L. formosana'' are unisexual. However, both sexes can be found in the same plant (Monoecy, monoecious). Male flowers are in catkins, female flowers form dense spherical heads, and the fruit is burr-like because of the persistent Style (botany), styles. Distribution and habitat ''Liquidambar formosana'' grow mostl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Fletcher Hance
Henry Fletcher Hance (4 Aug 1827 – 22 June 1886) was a British diplomat who devoted his spare time to the study of Chinese plants. Born in Brompton, London, his first appointment was to Hong Kong in 1844. In May 1852 in Exeter he married his first wife Anne Edith Baylis, who accompanied him on his return to Hong Kong. He later became vice-consul (1861–1878) to Whampoa, consul (1878–1881) to Canton, and finally consul to Xiamen, where he died in 1886. In 1873, Hance published a supplement to George Bentham's 1861 He graduated as Philosophiae Doctor from the University of Giessen on 24 November 1849, during which time he was in China. He found, named and described (in Latin) '' Iris speculatrix'' in 1875. He was the taxonomic author of many plants. In 1857 Berthold Carl Seemann named the genus ''Hancea'' (family Euphorbiaceae) in his honour. In 1878 Hance was elected a fellow of the Linnean Society of London. His first wife made paintings of flowers in Hong Kong. They ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Altingiaceae
Altingiaceae is a small family of flowering plants in the order Saxifragales, Peter F. Stevens (2001 onwards). "Altingiaceae". At: Angiosperm Phylogeny Website. At: Missouri Botanical Garden Website. (see ''External links'' below) consisting of wind-pollinated trees that produce hard, woody fruits containing numerous seeds. The fruits have been studied in considerable detail.Stephanie M.

Palmate
The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "acuminate", "lanceolate", or "linear" could ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monoecy
Monoecy (; adj. monoecious ) is a sexual system in seed plants where separate male and female cones or flowers are present on the same plant. It is a monomorphic sexual system alongside gynomonoecy, andromonoecy and trimonoecy. Monoecy is connected to anemophily. It can prevent self-pollination in an individual flower but cannot prevent self-pollination between male and female flowers on the same plant. Monoecy in angiosperms has been of interest for evolutionary biologists since Charles Darwin. Terminology Monoecious comes from the Greek words for one house. History The term monoecy was first introduced in 1735 by Carl Linnaeus. Darwin noted that the flowers of monoecious species sometimes showed traces of the opposite sex function. Monoecious hemp was first reported in 1929. Occurrence Monoecy is most common in temperate climates and is often associated with inefficient pollinators or wind-pollinated plants. It may be beneficial to reducing pollen-stigma interferenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catkin
A catkin or ament is a slim, cylindrical flower cluster (a spike), with inconspicuous or no petals, usually wind-pollinated (anemophilous) but sometimes insect-pollinated (as in ''Salix''). They contain many, usually unisexual flowers, arranged closely along a central stem that is often drooping. They are found in many plant families, including Betulaceae, Fagaceae, Moraceae, and Salicaceae. Occurrence Catkin-bearing plants include many trees or shrubs such as birch, willow, aspen, hickory, sweet chestnut, and sweetfern (''Comptonia''). In many of these plants, only the male flowers form catkins, and the female flowers are single ( hazel, oak), a cone (alder), or other types (mulberry). In other plants (such as poplar), both male and female flowers are borne in catkins. In Britain, they can be seen in January or February, when many trees are bare for winter. They can even occur in December. Evolution For some time, catkins were believed to be a key synapomorphy among the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Style (botany)
The stigma () is the receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower. Description The stigma, together with the style and ovary (typically called the stigma-style-ovary system) comprises the pistil, which is part of the gynoecium or female reproductive organ of a plant. The stigma itself forms the distal portion of the style, or stylodia, and is composed of , the cells of which are receptive to pollen. These may be restricted to the apex of the style or, especially in wind pollinated species, cover a wide surface. The stigma receives pollen and it is on the stigma that the pollen grain germinates. Often sticky, the stigma is adapted in various ways to catch and trap pollen with various hairs, flaps, or sculpturings. The pollen may be captured from the air (wind-borne pollen, anemophily), from visiting insects or other animals ( biotic pollination), or in rare cases from surrounding water (hydrophily). Stigma can vary from long and slen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liquidambar
''Liquidambar'', commonly called sweetgum (star gum in the UK), gum, redgum, satin-walnut, or American storax, is the only genus in the flowering plant family Altingiaceae and has 15 species. They were formerly often treated in Hamamelidaceae. They are native to Southeast and east Asia, the eastern Mediterranean and eastern North America. They are decorative deciduous trees that are used in the wood industry and for ornamental purposes. Etymology Both the scientific and common names refer to the sweet resinous sap (''liquid amber'') exuded by the trunk when cut. Species Extant species Fossils * †'' Liquidambar changii'' - Miocene (Washington state, North America) Description They are all large, deciduous trees, tall, with palmately 3- to 7-lobed leaves arranged spirally on the stems and length of , having a pleasant aroma when crushed. Their leaves can be many colors such as bright red, orange, yellow, and even purple. Mature bark is grayish and vertically groove ...

Trees Of China
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 c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
