Pinus Douglasiana
''Pinus gordoniana'' (Gordon's pine; syn. ''Pinus douglasiana'') is a species of evergreen conifer in the family Pinaceae, endemic to Mexico. Another common name is Douglas pine, but that name is sometimes applied to the unrelated species ''Pseudotsuga menziesii'' which is usually known as Douglas-fir. Description ''Pinus gordoniana'' is typically a tall tree, up to 35–45 m in height, with a single straight trunk up to 100 cm in diameter at the base. In mature trees the trunk is often clear of branches for 2/3 of the tree's height. The crown is pyramidal in young trees, becoming rounded in older trees, and varying from dense to open. In young trees and new branches the bark is smooth and red-brown. As trees mature the bark becomes rough and scaly, and divided into large irregular plates by deep fissures. The leaves are in fascicles of five, 20–35 cm long; the cones are orange-brown, 7–12 cm long, the scales with a rugose, radially striated surface. Habi ...

Synonym (biology)
In taxonomy, the scientific classification of living organisms, a synonym is an alternative scientific name for the accepted scientific name of a taxon. The botanical and zoological codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that now goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called '' Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank – for example, the name ''Papilio prorsa'' Linnaeus, 17 ...

Pinus Pseudostrobus
''Pinus pseudostrobus'', known in English as the smooth-bark Mexican pine and in Spanish as ''chamite'' or ''pacingo'', is a tree found in forests of Mexico and Central America. It is 8 to 25 m tall with a dense and round top.It is threatened by logging and wood harvesting. The bark is brown and fissured and smooth when young. It is subject to ''ex situ'' conservation. It grows at altitudes between 850 and 3250 m. from 26° to 15° north latitude, from Sinaloa, Mexico to Nicaragua and Honduras. It occurs within a rainfall regime that rains mostly in summer. In some forested areas like southern Nuevo León ''Pinus pseudostrobus'' is the tree with largest volume per hectare. English botanist John Lindley described the species in 1839. It is divided into ''Pinus pseudostrobus'' var.''apulcensis'' ( Lindl.)Shaw (Apulco pine), ''Pinus pseudostrobus'' f.''protuberans'' Martínez and ''Pinus pseudostrobus'' var.''pseudostrobus''.

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups w ...

Least Concern
A least-concern species is a species that has been evaluated and categorized by the International Union for Conservation of Nature (IUCN) as not being a focus of wildlife conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the " Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15,636) in the IUCN database still use the code "LR/lc", which indicates they have not been re- ...

Arceuthobium Globosum
The genus ''Arceuthobium'', commonly called dwarf mistletoes, is a genus of 42 species of parasitic plants that parasitize members of Pinaceae and Cupressaceae in North America, Central America, Asia, Europe, and Africa. Of the 42 species that have been recognized, 39 and 21 of these are endemic to North America and the United States, respectively. They all have very reduced shoots and leaves (mostly reduced to scales) with the bulk of the plant living under the host's bark. Recently the number of species within the genus has been reduced to 26 as a result of more detailed genetic analysis. Description They are dioecious, individual plants being either male or female. The fruit is unusual in that it builds up hydrostatic pressure internally when ripe and shoots the single sticky seed up to speeds nearly , an example of rapid plant movement. The lodgepole pine dwarf mistletoe,'' Arceuthobium americanum, has been found to explosively-disperse its seeds through thermogenesis.

Cupressus Lusitanica
''Hesperocyparis lusitanica'', the Mexican cypress, cedar-of-Goa or Goa cedar, is a species of Cupressaceae, cypress native to Mexico and Central America (Guatemala, El Salvador and Honduras). It has also been introduced to Belize, Costa Rica and Nicaragua, growing at altitude. The scientific name ''lusitanica'' (of Portugal) refers to its very early cultivation there, with plants imported from Mexico to the monastery at Buçaco Forest, Buçaco, near Coimbra in Portugal in about 1634; these trees were already over 130 years old when the species was botanically described by Philip Miller, Miller in 1768. In Mexico, the tree is also known as ''cedro blanco'' (white cedar) or ''teotlate''. Description ''Hesperocyparis lusitanica'' is an evergreen conifer tree with a conic to ovoid-conic crown, growing to 40 m tall. The foliage grows in dense sprays, dark green to somewhat yellow-green in colour. The leaves are scale-like, 2–5 mm long, and produced on rounded (not flattene ...

Picea
A spruce is a tree of the genus ''Picea'' ( ), a genus of about 40 species of coniferous evergreen trees in the family Pinaceae, found in the northern temperate and boreal (taiga) regions of the Northern hemisphere. ''Picea'' is the sole genus in the subfamily Piceoideae. Spruces are large trees, from about 20 to 60 m (about 60–200 ft) tall when mature, and have whorled branches and conical form. Spruces can be distinguished from other genera of the family Pinaceae by their needles (leaves), which are four-sided and attached singly to small persistent peg-like structures ( pulvini or sterigmata) on the branches, and by their cones (without any protruding bracts), which hang downwards after they are pollinated. The needles are shed when 4–10 years old, leaving the branches rough with the retained pegs. In other similar genera, the branches are fairly smooth. Spruce are used as food plants by the larvae of some Lepidoptera (moth and butterfly) species, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abies
Firs are evergreen coniferous trees belonging to the genus ''Abies'' () in the family Pinaceae. There are approximately 48–65 extant species, found on mountains throughout much of North and Central America, Eurasia, and North Africa. The genus is most closely related to '' Keteleeria'', a small genus confined to eastern Asia. The genus name is derived from the Latin "to rise" in reference to the height of its species. The common English name originates with the Old Norse ''fyri'' or the Old Danish ''fyr''. They are large trees, reaching heights of tall with trunk diameters of when mature. Firs can be distinguished from other members of the pine family by the way in which their needle-like leaves are attached singly to the branches with a base resembling a suction cup, and by their cones, which, like those of cedars, stand upright on the branches like candles and disintegrate at maturity. Identification of the different species is based on the size and arrangement o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
