Keteleeria
''Keteleeria'' is a genus of three species of coniferous trees in the family Pinaceae first described as a genus in 1866. The genus name ''Keteleeria'' honours J.B. Keteleer (1813–1903), a French nurseryman. The group is related to the genera ''Nothotsuga'' and ''Pseudolarix''. It is distinguished from ''Nothotsuga'' by the much larger cones, and from ''Pseudolarix'' by the evergreen leaves and the cones not disintegrating readily at maturity. All three genera share the unusual feature of male cones produced in umbels of several together from a single bud, and also in their ability, very rare in the Pinaceae, of being able to coppice. The genus is found in southern China (from Shaanxi south to Guangdong and Yunnan), Hainan, Taiwan, northern Laos, and Vietnam. They are evergreen trees reaching tall. The leaves are flat, needle-like, long and broad. The cones are erect, long, and mature in about 6–8 months after pollination; cone size and scale shape is very variable with ...

Keteleeria Davidiana
''Keteleeria davidiana'' ( zh: 铁坚油杉) is a coniferous evergreen tree native to Taiwan and southeast China, in the provinces of Gansu, Guangxi, Guizhou, Hubei, Hunan, Shaanxi, Sichuan, and Yunnan. It also occurs in the very northern part of Vietnam. The tree is restricted to hills, mountains, and valleys at elevations of 200–1500 m. Generally, it grows in regions with a more continental climate than the other two ''Keteleeria'' species. The tree reaches 40–50 m in height, developing an irregular oblate crown with large branches. The branchlets have a dense covering of stiff hairs. The bark is dull brown to dark gray-black, and is scaly or flaky. The leaves are needle-like, 2-6.4 cm long by 3.6-4.2 mm broad. They are flat, stiff, and dark shiny green. The cones are light brown, cylindrical, and stand erect on the branches. They are 8–20 cm long and 4–5 cm broad with a stalk 2.5-3.2 cm long. The winged oblong seed A seed is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keteleeria Fortunei
''Keteleeria fortunei'' ( zh: 油杉, ''you shan'') is a coniferous evergreen tree. Originated in China, ''K. fortunei'' is an ancient relict species and a second-class national key protected plant, "mainly distributed in south subtropical to the middle subtropical edge". It is found in the provinces of Fujian, Guangdong, Guangxi, Guizhou, Hunan, Jiangxi, Yunnan, and Zhejiang. The tree grows in hills, mountains, and broadleaf forests at elevations of 200–1400 m. The lifespan of ''K. fortunei'' can reach more than a thousand years, and the height of a thousand-year-old tree can reach more than 40 meters. "Economically, ''K. fortunei'' is a treasure, and its comprehensive development and uses has broad prospects". The species is named after Scottish botanist Robert Fortune, who discovered the tree in 1844. ''K. fortunei'' has also been reported from Vietnam but this is attributed to misidentification of immature specimens of '' Pseudotsuga sinensis''. Description It grows 25–3 ...

Nothotsuga
''Nothotsuga'' is a genus of coniferous trees in the family Pinaceae endemic to China. ''Nothotsuga'' contains only one species, ''Nothotsuga longibracteata'', commonly known as the bristlecone hemlock, which is found in southeastern China, in southern Fujian, northern Guangdong, northeast Guangxi, northeast Guizhou, and southwest Hunan. Description ''N. longibracteata'' is an evergreen tree reaching tall. The leaves are flat, needle-like, long and broad, very similar to those of ''Tsuga''. The cones are very similar to those of ''Keteleeria'', but smaller, long, erect, and mature in about 6–8 months after pollination. Taxonomy In many respects, ''Nothotsuga'' is intermediate between the genera ''Keteleeria'' and ''Tsuga''. It was discovered in 1932, and at first treated as ''Tsuga longibracteata'', being classified in its own genus in 1989 when new research indicated how distinct it is from other species of ''Tsuga'' - by the larger, erect cones with exserted bracts, ...

Pinaceae
The Pinaceae, or pine family, are conifer trees or shrubs, including many of the well-known conifers of commercial importance such as Cedrus, cedars, firs, Tsuga, hemlocks, larches, pines and spruces. The family is included in the order Pinales, formerly known as Coniferales. Pinaceae are supported as monophyletic by their protein-type sieve cell plastids, pattern of proembryogeny, and lack of bioflavonoids. They are the largest extant conifer family in species diversity, with between 220 and 250 species (depending on Taxonomy (biology), taxonomic opinion) in 11 genera, and the second-largest (after Cupressaceae) in geographical range, found in most of the Northern Hemisphere, with the majority of the species in temperate climates, but ranging from subarctic to tropical. The family often forms the dominant component of Boreal forest, boreal, coastal, and montane forests. One species, ''Pinus merkusii'', grows just south of the equator in Southeast Asia. Major centre of diversity, c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudolarix
''Pseudolarix'' is a genus of coniferous trees in the pine family Pinaceae containing three species, the extant ''Pseudolarix amabilis'' and the extinct species '' Pseudolarix japonica'' and '' Pseudolarix wehrii''. ''Pseudolarix'' species are commonly known as golden larch, but are not true larches (''Larix'') being more closely related to ''Keteleeria'', ''Abies'' and ''Cedrus''. ''P. amabilis'' is native to eastern China, occurring in small areas in the mountains of southern Anhui, Zhejiang, Fujian, Jiangxi, Hunan, Hubei and eastern Sichuan, at altitudes of . ''P. wehrii'' is described from fossils dating to the Early Eocene (Ypresian), of Western North America where it is found in the Eocene Okanagan Highlands Allenby and Klondike Mountain Formations. The youngest known occurrence is of mummified fossils found in the Late Eocene Buchanan Lake Formation on Axel Heiberg Island. ''P. japonica'' is known from Middle Miocene to Pliocene sediments in Japan and Miocene deposits o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abies Fabri
''Abies fabri'' (Faber's fir) is a conifer species in the family Pinaceae. It is endemic to Sichuan in western China, occurring on the sacred mountain of Emei Shan (from where it was first described) and westward to the Gongga Shan massif, growing at altitudes of .Flora of China: It is a tree growing to tall, with a trunk up to a metre in diameter, and a conical to broad columnar crown. The shoots are yellowish-brown, hairless or slightly hairy. The leaves are linear, long and wide, glossy dark green above, and with two white stomatal bands below; the leaf margins are slightly revolute. The cones are cylindrical, dark purple when immature, ripening purple-blue, long and wide, with slightly exserted bracts. The most serious threat to ''Abies fabri'' seems to be acid rain from nearby industries in Chengdu. There are two subspecies: *''Abies fabri'' subsp. ''fabri''.

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