Taxus sumatrana (Miquel) de Laub. | |
Taxus sumatrana, or the Sumatran yew, is a large evergreen shrub and one of the eight species of yew. Its taxonomic namesake is indicative of the species being found in Indonesia (specifically, the island of Sumatra); however, T. sumatrana is also found in a number of South and Southeast Asian countries, including parts of Afghanistan, Bangladesh, Bhutan, China, India, Indochina, Nepal, Pakistan, the Philippines, Taiwan, and Tibet. [2] : 351 Given this broad geographical range, it is also known as the Taiwan yew, the Chinese yew, as well as the East Himalayan yew. [3] Plants of the World Online recognizes T. sumatrana as a synonym of Taxus wallichiana . [4]
T. sumatrana is typically found at elevations ranging from 400 to 3,100 m [5] and mainly in subtropical forests or on highland ridges. It is a government-protected species in Taroko National Park in Taiwan.
Taxus sumatrana is a wide-trunked, bushy shrub that will eventually develop into a tree, attaining an average height of 14 m (approx. 45 feet). Its leaves are around 1.2–2.7 cm long and 2–2.5 mm wide (around 1”x1”), growing in two ranks along the branches and abruptly spiraling into an apex at the tip. [5] The foliage a pale yellow-green colour on the topside, with light green underneath. Its bark is grey-red which exfoliates in irregular, 1.5 mm (half an inch) thick flakes, which leave yellowish scars on the trunk almost immediately upon cutting. [5]
The Chinese yew has fleshy seeds that ripen into a red colour 6 mm long by 5 mm wide with flesh 4 mm thick. [2] : 350–351
The wood is suitable as timber, but it grows very slow to be financially viable. [2] : 351
On the Indian Subcontinent, the oil of T. sumatrana is traditionally used to mark a red tilaka on the foreheads of Brahmins. Chinese yews are also used for the crafting of clogs, whip handles, bed frames and bows (archery).
Taxus is a genus of coniferous trees or shrubs known as yews in the family Taxaceae. Yews occur around the globe in temperate zones of the northern hemisphere, northernmost in Norway and southernmost in the South Celebes. Some populations exist in tropical highlands.
Taxaceae, commonly called the yew family, is a coniferous family which includes six extant and two extinct genera, and about 30 species of plants, or in older interpretations three genera and 7 to 12 species.
Taxus baccata is a species of evergreen tree in the family Taxaceae, native to Western Europe, Central Europe and Southern Europe, Northwest Africa, northern Iran, and Southwest Asia. It is the tree originally known as yew, though with other related trees becoming known, it may be referred to as the common yew, English yew, or European yew. It is primarily grown as an ornamental. Most parts of the plant are poisonous, with toxins that can be absorbed through inhalation and through the skin; consumption of even a small amount of the foliage can result in death.
Pseudotaxus chienii, the whiteberry yew, is a species of plant in the yew family, Taxaceae. It is the sole species in the genus Pseudotaxus, but closely related to the other yews in the genus Taxus. It is endemic to southern China, occurring in northern Guangdong, northern Guangxi, Hunan, Southwest Jiangxi and southern Zhejiang.
Taxus cuspidata, the Japanese yew or spreading yew, is a member of the genus Taxus, native to Japan, Korea, northeast China and the extreme southeast of Russia.
Taxus brevifolia, the Pacific yew or western yew, is a species of tree in the yew family Taxaceae native to the Pacific Northwest of North America. It is a small evergreen conifer, thriving in moisture and otherwise tending to take the form of a shrub.
Phyllocladus aspleniifolius, commonly known as the celerytop pine, is an endemic gymnosperm of Tasmania, Australia. It is widespread and common in Tasmania, with the most abundance in the western highlands. Its ‘leaves’ appear similar to those of a celery plant, hence the common name.
Taxus canadensis, the Canada yew or Canadian yew, is a conifer native to central and eastern North America, thriving in swampy woods, ravines, riverbanks and on lake shores. Locally called simply "yew", this species is also referred to as American yew or ground-hemlock.
Taxus celebica is a large, evergreen shrub or tree of the yew family (Taxaceae), widespread in China at elevations up to 900 meters. It is commonly called Chinese yew though the term also refers to the Taxus chinensis or Taxus sumatrana.
Taxus wallichiana, the Himalayan yew, is a species of yew, native to the Himalaya and parts of south-east Asia. The species has a variety of uses in traditional medicine. It is currently classified as endangered by the IUCN.
Taxus chinensis is a species of yew. It is commonly called the Chinese yew, though this term also refers to Taxus celebica or Taxus sumatrana.
Taxus floridana, the Florida yew, is a species of yew, endemic to a small area of under 10 km² on the eastern side of the Apalachicola River in mesophytic forests of northern Florida at altitudes of 15–40 m. It is listed as critically endangered. It is protected in reserves at the Torreya State Park and at the Nature Conservancy's Apalachicola Bluffs and Ravines Preserve, and has legal protection under the United States and Florida Endangered Species laws.
Taxus globosa, the Mexican yew, is an evergreen shrub and one of the eight species of yew. The Mexican yew is a rare species, only known to be found in a small number of locations in eastern Mexico, Guatemala, El Salvador and Honduras, and is listed as an endangered species. The Mexican yew is a shrub that grows to an average height of 4.6m. It has large, sharp light green needles growing in ranks on either side of its branches.
Tsuga chinensis, commonly referred to as the Taiwan or Chinese hemlock, or in Chinese as tieshan, is a coniferous tree species native to China, Taiwan, Tibet and Vietnam. The tree is quite variable and has many recognised varieties, though some are also maintained to be separate species by certain authorities. The tree was recently discovered in the mountains of northern Vietnam, making that the southernmost extension of its range.
Leucopogon parviflorus, commonly known as coast beard-heath or native currant, is a shrub or small tree in the family Ericaceae. It is native to all Australian states and territories excluding the Northern Territory and the ACT and also grows in New Zealand.
