Platycladus Orientalis
''Platycladus'' is a monotypic genus of evergreen coniferous trees in the cypress family Cupressaceae, containing only one species, ''Platycladus orientalis'', also known as Chinese thuja, Oriental arborvitae, Chinese arborvitae, biota or Oriental thuja. It is native to northeastern parts of East Asia and North Asia, but is also now naturalised as an introduced species in other regions of the Asian continent. Description A monoecious tree, it is small, slow-growing, reaching and trunk diameter (exceptionally to tall and diameter in very old trees). The foliage forms in flat sprays with scale-like leaves long, which are bright green in colour but may turn brownish or coppery orange in winter. The cones are long, green ripening brown in about eight months from pollination, and have 6–12 thick scales arranged in opposite pairs. The seeds are long, with no wing. The branches are relatively short, loosely arranged and, usually, sharply directed upwards, and the bark, br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Simatai
Simatai (), a section of the Great Wall of China located in the north of Miyun County, 120 km northeast of Beijing, holds the access to Gubeikou, a strategic pass in the eastern part of the Great Wall. It was closed in June 2010 but has been reopened to tourists since 2014. General The section was originally built during the Northern Qi dynasty (550–577) and rebuilt during the Hongwu Emperor's reign during the Ming dynasty. Simatai Great Wall is 5.4 km long with 35 beacon towers. This section of the Great Wall incorporated the different characteristics of each section of the Great Wall. A specialist on the Great Wall, Professor Luo Zhewen, has said that "The Great Wall is the best of the Chinese buildings, and Simatai is the best of the Great Wall."

Grafting
Grafting or graftage is a horticultural technique whereby tissues of plants are joined so as to continue their growth together. The upper part of the combined plant is called the scion () while the lower part is called the rootstock. The success of this joining requires that the vascular tissues grow together and such joining is called inosculation. The technique is most commonly used in asexual propagation of commercially grown plants for the horticultural and agricultural trades. In most cases, one plant is selected for its roots and this is called the stock or rootstock. The other plant is selected for its stems, leaves, flowers, or fruits and is called the scion or cion. The scion contains the desired genes to be duplicated in future production by the stock/scion plant. In stem grafting, a common grafting method, a shoot of a selected, desired plant cultivar is grafted onto the stock of another type. In another common form called bud grafting, a dormant side bud is g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microbiota Decussata
''Microbiota'' is a monotypic genus of evergreen coniferous shrubs in the cypress family Cupressaceae, containing only one species, ''Microbiota decussata'' (Siberian carpet cypress, Russian arbor-vitae). The plant is native and endemic to a limited area of the Sikhote-Alin mountains in Primorskiy Krai in the Russian Far East. ''Microbiota'' is not to be confused with the range of microorganisms of the same name. The genus name was derived from ''micro-'', meaning "small", + ''Biota'', the genus name for a closely related conifer, a species formerly called ''Biota orientalis'', now renamed ''Platycladus orientalis.'' Description ''Microbiota decussata'' is a prostrate shrub to in height, and in spreading width. The foliage forms flat sprays with scale-like leaves 2–4 mm long. The cones are among the smallest of any conifer, 2–3 mm long, green ripening brown in about eight months from pollination, and have four scales arranged in two opposite pairs. The seeds ar ...

Decussate
Decussation is used in biological contexts to describe a crossing (due to the shape of the Roman numeral for ten, an uppercase 'X' (), ). In Latin anatomical terms, the form is used, e.g. . Similarly, the anatomical term chiasma is named after the Greek uppercase 'Χ' (chi). Whereas a decussation refers to a crossing within the central nervous system, various kinds of crossings in the peripheral nervous system are called chiasma. Examples include: * In the brain, where nerve fibers obliquely cross from one lateral side of the brain to the other, that is to say they cross at a level other than their origin. See for examples Decussation of pyramids and sensory decussation. In neuroanatomy, the term ''chiasma'' is reserved for crossing of- or within nerves such as in the optic chiasm. * In botanical leaf taxology, the word ''decussate'' describes an opposite pattern of leaves which has successive pairs at right angles to each other (i.e. rotated 90 degrees along the stem w ...

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 Climate is the long-term weather p ...

Conifer Cone
A conifer cone (in formal 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 reproductive structures. The woody cone is the female cone, which produces seeds. The male cone, which produces pollen, is usually herbaceous and much less conspicuous even at full maturity. The name "cone" derives from Greek ''konos'' (pine cone), which also gave name to the 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 ways (mostly in scale arrangement) from species to ...

Chartreuse (color)
Chartreuse (, , ), also known as yellow-green, is a color between yellow and green. It was named because of its resemblance to the green color of a French liqueur called '' green chartreuse'', introduced in 1764. Similarly, ''chartreuse yellow'' is a yellow color mixed with a small amount of green; it was named because of its resemblance to the color of another French liqueur called '' yellow chartreuse'', introduced in 1838. Shades of chartreuse History and etymology The French word ''chartreuse'' means "charterhouse". The monasteries of the monks of the Carthusian order, of which the first one was established in 1082 by Saint Bruno, are called charter houses because they were chartered—and given generous material support—by the Duke of Burgundy, known as Philip the Bold, when he took over the area in 1378. Philip the Bold's elaborately decorated tomb was initially installed at a Carthusian charterhouse when he died in 1404. These monks started producing Chartreuse liq ...

Leaves
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 lig ...
