Athrotaxidoideae
''Athrotaxis'' is a genus of two to three species (depending on taxonomic opinion) of conifers in the cypress family, Cupressaceae. The genus is endemic to western Tasmania, where they grow in high altitude temperate rainforests.Farjon, A. (2005). ''Monograph of Cupressaceae and Sciadopitys''. Royal Botanic Gardens, Kew. Australian Plant Names Index''Athrotaxis''/ref> They are medium-sized evergreen trees, reaching 10–30 m (rarely 40 m) tall and 1-1.5 m trunk diameter. The leaves are scale-like, 3–14 mm long, are borne spirally on the shoots. The cones are globose to oval, 1–3 cm diameter, with 15-35 scales, each scale with 3-6 seeds; they are mature in 7–9 months after pollination, when they open to release the seeds. The male (pollen) cones are small, and shed their pollen in early spring. They are very susceptible to bush fires, and have declined markedly in abundance due to accidental and deliberate fires since the European colonisation of Tasmania. Tax ...

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 ...

Sequoioideae
Sequoioideae, popularly known as redwoods, is a subfamily of coniferous trees within the family Cupressaceae. It includes the largest and tallest trees in the world. Description The three redwood subfamily genera are '' Sequoia'' from coastal California and Oregon, ''Sequoiadendron'' from California's Sierra Nevada, and ''Metasequoia'' in China. The redwood species contains the largest and tallest trees in the world. These trees can live for thousands of years. Threats include logging, fire suppression, climate change, illegal marijuana cultivation, and burl poaching. Only two of the genera, ''Sequoia'' and ''Sequoiadendron'', are known for massive trees. Trees of ''Metasequoia'', from the single living species ''Metasequoia glyptostroboides'', are much smaller. Taxonomy and evolution Multiple studies of both morphological and molecular characters have strongly supported the assertion that the Sequoioideae are monophyletic. Most modern phylogenies place ''Sequoia'' as si ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Christopher J
Christopher is the English version of a Europe-wide name derived from the Greek name Χριστόφορος (''Christophoros'' or '' Christoforos''). The constituent parts are Χριστός (''Christós''), "Christ" or "Anointed", and φέρειν (''phérein''), "to bear"; hence the "Christ-bearer". As a given name, 'Christopher' has been in use since the 10th century. In English, Christopher may be abbreviated as "Chris", "Topher", and sometimes " Kit". It was frequently the most popular male first name in the United Kingdom, having been in the top twenty in England and Wales from the 1940s until 1995, although it has since dropped out of the top 100. The name is most common in England and not so common in Wales, Scotland, or Ireland. People with the given name Antiquity and Middle Ages * Saint Christopher (died 251), saint venerated by Catholics and Orthodox Christians * Christopher (Domestic of the Schools) (fl. 870s), Byzantine general * Christopher Lekapenos (died 931) ...

Athrotaxis Cupressoides (31258346526)
''Athrotaxis cupressoides'', is also known as pencil pine, despite being a species of the family Cupressaceae, and not a member of the pine family. Found either as an erect shrub or as a tree, this species is endemic to Tasmania, Australia. Trees can live for upwards of 1000 years, sustaining a very slow growth rate of approximately 12 mm in diameter per year. As with all species in the ''Athrotaxis'' genus, ''A. cupressoides''’ leaves are single-veined and arranged in spirals. Unique to ''A. cupressoides'' the leaves are 2-3mm long/wide, overlapping and closely compressed stem. This results in a scale like appearance. Two forms of woody cones act as the gametophyte structures, which mature approximately six months after pollination and are typically retained on the tree for up to one year. The female cones are spherical with pointed bract scales 12-15 mm in diameter. The male cones are much smaller 3-5 mm in diameter. The common name pencil pine is based on it being an eve ...

Athrotaxis Laxifolia
Description ''Athrotaxis laxifolia'' is an evergreen coniferous tree growing to 12–21 m tall with a conical, sparsely branched crown and a trunk up to 1m diameter. It is commonly known as the Summit or Yellow-Twig athrotaxis. The leaves are scale-like, 4–12 mm long and 2–3 mm broad, arranged spirally on the shoots. The seed cones are oblong-globose, 15–26 mm long and 14–20 mm diameter, with 14–18 spirally-arranged scales; they are mature about six months after pollination. The pollen cones are 3–5 mm long.Farjon, A. (2005). ''Monograph of Cupressaceae and Sciadopitys''. Royal Botanic Gardens, Kew. The bark of ''A. laxifolia'' is dark orange-brown, deeply fissured and flaky. The species name ''laxifolia'' refers to the wider spacing of the leaves as compared with the other conifers in its genus, ''Athrotaxis cuppressoides'' and ''Athrotaxis selaginoides''.

Athrotaxis Selaginoides
''Athrotaxis selaginoides'' is a species of ''Athrotaxis'', endemic to Tasmania in Australia, where it grows at 400–1,120 m altitude. In its habitat in the mountains, snow in winter is very usual. It is often called King Billy Pine or King William Pine (believed to be in reference to William Lanne an Aboriginal man), although it is not a true pine.Farjon, A. (2005). ''Monograph of Cupressaceae and Sciadopitys''. Royal Botanic Gardens, Kew. Description It is an evergreen coniferous tree growing to 20–30 m tall, with a trunk up to 1.5 m diameter. The leaves are claw-like, 7–18 mm long and 3–4 mm broad, arranged spirally on the shoots. The seed cones are globose, 15–30 mm diameter, with 20–30 spirally-arranged scales; they are mature about six months after pollination. The pollen cones are 4–5 mm long. Decline The main cause of past decline has been fire, with about one third of its habitat burnt in the twentieth century. Like the other two ''Athrotaxis'' species, ' ...
