Cunninghamia
''Cunninghamia'' is a genus of one or two living species of evergreen coniferous trees in the cypress family Cupressaceae. They are native to China, northern Vietnam and Laos, and perhaps also Cambodia. They may reach in height. In vernacular use, it is most often known as ''Cunninghamia'', but is also sometimes called "China-fir" (though it is not a fir). The genus name ''Cunninghamia'' honours Dr. James Cunningham, a British doctor who introduced this species into cultivation in 1702 and botanist Allan Cunningham. A female cone Cluster of male cones Description The general shape of the tree is conical with tiered, horizontal branches that are often somewhat pendulous toward the tips. ''Cunninghamia'' bears softly spined, leathery, stiff, green to blue-green needle-like leaves that spiral around the stem with an upward arch; they are 2–7 cm long and 3–5 mm broad at the base, and bear two white or greenish-white stomatal bands underneath and sometimes ...

Cunninghamia Lanceolata
''Cunninghamia lanceolata'' is a species of tree in the cypress family, Cupressaceae. It is native to south-central and southeast China. Ornamentally ''C. lanceolata'' is commonly planted as a specimen tree in temperate zones. Taxonomy '' Cunninghamia konishii'' is treated as a distinct species by some sources, although it has also been suggested that it is conspecific with ''C. lanceolata''. Though ''C. konishii'' may be treated as the same species, its primary distribution is in Taiwan, where as ''C. lanceolata'' is found in mainland China. ''Cunninghamia lanceolata'' was originally described in 1827 by English botanist William J. Hooker. Description ''Cunninghamia lanceolata,'' commonly known as Chinese fir, is a tall conifer able to reach heights of 150 feet (45.7 meters) in mild climates. In North America, the height typically ranges from 30 to 50 feet (9.1 to 15.2 meters). In native forest land in China heights can reach up to 150 feet (45.7 meters) and 30 to 70 ...

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 sh ...

Taxodiaceae
Taxodiaceae is a formerly recognized coniferous plant family comprising the following ten genera: *''Athrotaxis'' *''Cryptomeria'' *''Cunninghamia'' *†'' Cunninghamites'' *''Glyptostrobus'' *''Metasequoia'' *'' Sciadopitys'' *'' Sequoia'' *''Sequoiadendron'' *†'' Sequoioxylon'' *''Taiwania'' *'' Taxodium'' However, research has shown that the Taxodiaceae genera, with the exception of ''Sciadopitys'', are phylogenetically part of the family Cupressaceae. There are no consistent characters by which they can be separated, and genetic evidence demonstrates close relationships. The one exception, the genus ''Sciadopitys'', is genetically very distinct from all other conifers, and now treated in a family of its own, Sciadopityaceae. As proposed, genera of the former Taxodiaceae are grouped in the following subfamilies within the larger Cupressaceae: * Athrotaxidoideae Quinn (''Athrotaxis'') * Cunninghamioideae (Sieb. & Zucc.) Quinn (''Cunninghamia'') * Sequoioideae (Luerss.) Qu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allan Cunningham (botanist)
Allan Cunningham (13 July 1791 – 27 June 1839) was an English botanist and explorer, primarily known for his travels in Australia to collect plants. Early life Cunningham was born in Wimbledon, Surrey, England, the son of Allan Cunningham (head gardener at Wimbledon Park House), who came from Renfrewshire, Scotland, and his English wife Sarah (née Juson/Jewson née Dicken). Allan Cunningham was educated at a Putney private school, Reverend John Adams Academy and then went into a solicitor's office (a Lincoln's Inn Conveyancer). He afterwards obtained a position with William Townsend Aiton superintendent of Kew Gardens, and this brought him in touch with Robert Brown and Sir Joseph Banks. Brazil and Australia (New South Wales) On Banks' recommendation, Cunningham went to Brazil with James Bowie between 1814 and 1816 collecting specimens for Kew Gardens. On 28 September 1816 he sailed for Sydney where he arrived on 20 December 1816. He established himse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jurassic
The Jurassic ( ) is a geologic period and stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately Mya. The Jurassic constitutes the middle period of the Mesozoic Era and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic Magmatic Province. The beginning of the Toarcian Stage started around 183 million years ago and is marked by an extinction event associated with widespread oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and is the only boundary between geological periods to remain formally undefined. By the beginning of the Jurassi ...

Pinophyta
Conifers are a group of cone-bearing seed plants, a subset of gymnosperms. Scientifically, they make up the division Pinophyta (), also known as Coniferophyta () or Coniferae. The division contains a single extant class, Pinopsida. All extant conifers are perennial woody plants with secondary growth. The great majority are trees, though a few are shrubs. Examples include cedars, Douglas-firs, cypresses, firs, junipers, kauri, larches, pines, hemlocks, redwoods, spruces, and yews.Campbell, Reece, "Phylum Coniferophyta". Biology. 7th. 2005. Print. P. 595 As of 1998, the division Pinophyta was estimated to contain eight families, 68 genera, and 629 living species. Although the total number of species is relatively small, conifers are ecologically important. They are the dominant plants over large areas of land, most notably the taiga of the Northern Hemisphere, but also in similar cool climates in mountains further south. Boreal conifers have many wintertime adaptat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basal Shoot
Basal shoots, root sprouts, adventitious shoots, and suckers are words for various kinds of shoots that grow from adventitious buds on the base of a tree or shrub, or from adventitious buds on its roots. Shoots that grow from buds on the base of a tree or shrub are called basal shoots; these are distinguished from shoots that grow from adventitious buds on the roots of a tree or shrub, which may be called root sprouts or suckers. A plant that produces root sprouts or runners is described as surculose. Water sprouts produced by adventitious buds may occur on the above-ground stem, branches or both of trees and shrubs. Suckers are shoots arising underground from the roots some distance from the base of a tree or shrub. In botany and ecology In botany, a root sprout or sucker is a severable plant that grows not from a seed but from the meristem of a root at the base of or a certain distance from the original tree or shrub. Root sprouts may emerge a substantial distance from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bark (botany)
Bark is the outermost layers of stems and roots of woody plants. Plants with bark include trees, woody vines, and shrubs. Bark refers to all the tissues outside the vascular cambium and is a nontechnical term. It overlays the wood and consists of the inner bark and the outer bark. The inner bark, which in older stems is living tissue, includes the innermost layer of the periderm. The outer bark on older stems includes the dead tissue on the surface of the stems, along with parts of the outermost periderm and all the tissues on the outer side of the periderm. The outer bark on trees which lies external to the living periderm is also called the rhytidome. Products derived from bark include bark shingle siding and wall coverings, spices and other flavorings, tanbark for tannin, resin, latex, medicines, poisons, various hallucinogenic chemicals and cork. Bark has been used to make cloth, canoes, and ropes and used as a surface for paintings and map making. A number of pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
