Abietoideae
Abietoideae is a subfamily of the conifer family Pinaceae. The name is from the genus ''Abies'' ( firs), which contains most of the species in the genus. Six genera are currently assigned to this subfamily: ''Abies'', ''Cedrus'', ''Keteleeria'', ''Nothotsuga'', ''Pseudolarix'', and ''Tsuga''. ''Abies alba'' from Koehler (1887) The group was formerly treated as a separate family, the Abietaceae, by some plant taxonomy systems, such as the Wettstein system.

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.

Tsuga
''Tsuga'' (, from Japanese (), the name of ''Tsuga sieboldii'') is a genus of conifers in the subfamily Abietoideae of Pinaceae, the pine family. The common name hemlock is derived from a perceived similarity in the smell of its crushed foliage to that of the unrelated plant poison hemlock. Unlike the latter, ''Tsuga'' species are not poisonous. The genus comprises eight to ten species (depending on the authority), with four species occurring in North America and four to six in eastern Asia. Description They are medium-sized to large evergreen trees, ranging from tall, with a conical to irregular crown, the latter occurring especially in some of the Asian species. The leading shoots generally droop. The bark is scaly and commonly deeply furrowed, with the colour ranging from grey to brown. The branches stem horizontally from the trunk and are usually arranged in flattened sprays that bend downward towards their tips. Short spur shoots, which are present in many gymnosperms ...

Cedrus
''Cedrus'', common English name cedar, is a genus of coniferous trees in the plant family Pinaceae (subfamily Abietoideae). They are native plant, native to the mountains of the western Himalayas and the Mediterranean region, occurring at altitudes of 1,500–3,200 m in the Himalayas and 1,000–2,200 m in the Mediterranean.Farjon, A. (1990). ''Pinaceae. Drawings and Descriptions of the Genera''. Koeltz Scientific Books . Description ''Cedrus'' trees can grow up to 30–40 m (occasionally 60 m) tall with spicy-resinous scented wood, thick ridged or square-cracked Bark (botany), bark, and broad, level branches. The shoots are dimorphic and are made up of long shoots, which form the framework of the branches, and short shoots, which carry most of the leaves. The leaf, leaves are evergreen and needle-like, 8–60 mm long, arranged in an open spiral phyllotaxis on long shoots, and in dense spiral clusters of 15–45 together on short shoots; they vary fr ...

Abies Concolor
''Abies concolor'', the white fir, is a coniferous tree in the pine family Pinaceae. This tree is native to the mountains of western North America, including the Cascade Range and southern Rocky Mountains, and into the isolated mountain ranges of southern Arizona, New Mexico, and Northern Mexico. It naturally occurs at elevations between . It is popular as an ornamental landscaping tree and as a Christmas tree.

Abies Bracteata
''Abies bracteata'', the Santa Lucia fir or bristlecone fir, is the rarest and most endemic fir in North America, and according to some, the world. It is confined to steep-sided slopes and the bottoms of rocky canyons in the Santa Lucia Mountains, in the Big Sur region on the central coast of California, United States. Location The species may have had a broader range in Paleoendemic era, although some scientists say no fossil evidence of the tree has been conclusively identified. The tree is now confined, possibly due to long-term climatic changes, to a few, small locales that mimic those of the distant past. Fire susceptibility The fir tends to be concentrated in steep, rocky, fire-resistant spots at elevations from . Due to the tree's thin bark, it is susceptible to fire, and large stands are always located near high cliffs or in steep, rugged canyons that prevent litter accumulation under the tree canopy and limit the strength of fires. Known stands The fir curren ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abies Cephalonica
''Abies cephalonica'' or Greek fir is a fir native to the mountains of Greece, primarily in the Peloponnesos and the island of Kefallonia, intergrading with the closely related Bulgarian fir further north in the Pindus mountains of northern Greece. It is a medium-size evergreen coniferous tree growing to – rarely – tall and with a trunk diameter of up to . It occurs at altitudes of , on mountains with a rainfall of over . The leaves are needle-like, flattened, long and wide by thick, glossy dark green above, and with two blue-white bands of stomata below. The tip of the leaf is pointed, usually fairly sharply but sometimes with a blunt tip, particularly on slow-growing shoots on older trees. The cones are long and broad, with about 150–200 scales, each scale with an exserted bract and two winged seeds; they disintegrate when mature to release the seeds. It is also closely related to Nordmann fir to the east in northern Turkey. Uses Greek fir was important in the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abies Chensiensis
''Abies chensiensis'', the Shensi fir, is a fir native to Gansu, Hubei, Sichuan, Tibet, Yunnan in China, and Arunachal Pradesh in India. It was first described by Philippe Édouard Léon Van Tieghem in 1892. Description The Shensi fir is a straight-stemmed, evergreen tree, which can reach heights of up to and can have a diameter at breast height of up to .

Abies Cilicica
''Abies cilicica'', also known as Cilician fir or Taurus fir, is a species of conifer in the family Pinaceae. It is found in Lebanon, Syria, and Turkey. ''Abies cilicica'' and ''Cedrus libani'', together with Acer hyrcanum, ''Acer hyrcanum'' subsp. ''tauricolum'' and Sorbus torminalis, ''Sorbus torminalis'' subsp. ''orientalis'', are the predominant trees in the phytocoenosis Abeti-Cedrion, a type of forest of the middle and eastern Taurus Mountains of Turkey. These forests occur between 800 and 2,100 meters elevation. Over 5,000 years of logging, burning, and grazing have reduced these forests to enclaves. In 2009 at Berenice Troglodytica, the Egypto-Roman port on the Red Sea, archaeologists found: "two blocks of resin from the Syrian fir tree (''Abies cilicica''), one weighing about 190 g and the other about 339 g, recovered from 1st-century AD contexts in one of the harbour trenches.

''Abies delavayi'', the Delavay's silver-fir or Delavay's fir, is a species of fir, native to Yunnan in southwest China and adjoining border areas in southeastern Tibet, far northeastern India, northern Myanmar, and far northwestern Vietnam. It is a high altitude mountain tree, growing at elevations of 3,000–4,000 m (exceptionally down to 2,400 m and up to 4,300 m), often occupying the tree line. The species is named after its discoverer, Father Pierre Jean Marie Delavay, who collected it at 3,500–4,000 m on the Cang Mountain near Dali.Franchet, A. (1899). Plantarum Sinensium.

Abies Beshanzuensis
''Abies beshanzuensis'' (Baishanzu fir, Baishan fir) is a species of fir (genus ''Abies'') in the family Pinaceae. It is endemism, endemic to Baishanzu, Mt. Baishanzu in southern Zhejiang province in eastern China, where it grows at altitude and is threatened by collection and climate change. The site is within the Fengyangshan – Baishanzu National Nature Reserve. ''Abies beshanzuensis'' is classified as critically endangered by the IUCN Red List. It was discovered in 1963 on the summit of Baishanzu Shan (1,857 m), where only seven trees were found. Three of these were dug up and moved to Beijing Botanical Garden, where they died. By 1987, only three trees were left in the wild, making it the rarest conifer in the world. New planting of grafted plants on Baishanzu Shan and other nearby sites has shown some success, but the species remains critically endangered. It is a tree growing to tall, with a broad conic crown and a trunk up to in diameter. The shoots are stout, pale ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
