Platycladus
''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, brownis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cupressaceae
Cupressaceae is a conifer family, the cypress family, with worldwide distribution. The family includes 27–30 genera (17 monotypic), which include the junipers and redwoods, with about 130–140 species in total. They are monoecious, subdioecious or (rarely) dioecious trees and shrubs up to tall. The bark of mature trees is commonly orange- to red- brown and of stringy texture, often flaking or peeling in vertical strips, but smooth, scaly or hard and square-cracked in some species. Description The leaves are arranged either spirally, in decussate pairs (opposite pairs, each pair at 90° to the previous pair) or in decussate whorls of three or four, depending on the genus. On young plants, the leaves are needle-like, becoming small and scale-like on mature plants of many genera; some genera and species retain needle-like leaves throughout their lives. Old leaves are mostly not shed individually, but in small sprays of foliage (cladoptosis); exceptions are leaves on the s ...

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 are ...

Thuja
''Thuja'' ( ) is a genus of coniferous tree or shrub in the Cupressaceae (cypress family). There are five species in the genus, two native to North America and three native to eastern Asia. The genus is monophyletic and sister to ''Thujopsis''. Members are commonly known as arborvitaes (from the Latin term for 'tree of life'), thujas or cedars. Description ''Thuja'' are evergreen trees growing from tall, with stringy-textured reddish-brown bark. The shoots are flat, with side shoots only in a single plane. The leaves are scale-like and long, except young seedlings in their first year, which have needle-like leaves. The scale leaves are arranged in alternating decussate pairs in four rows along the twigs. The male cones are small, inconspicuous, and are located at the tips of the twigs. The female cones start out similarly inconspicuous, but grow to about long at maturity when 6–8 months old; they have 6-12 overlapping, thin, leathery scales, each scale bearing 1–2 small se ...

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] |
North Asia
North Asia or Northern Asia, also referred to as Siberia, is the northern region of Asia, which is defined in geographical terms and is coextensive with the Asian part of Russia, and consists of three Russian regions east of the Ural Mountains: Ural, Siberia, and the Russian Far East. North Asia is bordered by the Arctic Ocean to its north; by Eastern Europe to its west; by Central and East Asia to its south; and by the Pacific Ocean and North America to its east. It covers an area of , or 8.8% of Earth's total land area; and is the largest subregion of Asia by area, but is also the least populated, with a population of around 33 million, accounting for merely 0.74% of Asia's population. Topographically, the region is dominated by the Eurasian Plate, except for its eastern part, which lies on the North American, Amurian, and Okhotsk Plates. It is divided by three major plains: the West Siberian Plain, Central Siberian Plateau, and Verhoyansk-Chukotka collision zone. The Uralia ...

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 gra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 when ...

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 ...

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 lique ...
