Quercus Brandegeei
''Quercus brandegeei'' is a rare Mexican species of plant in the beech family, Fagaceae, in the oak genus ''Quercus'', series '' Virentes''. It has been found only in the southern part of the State of Baja California Sur in northwestern Mexico. ''Quercus brandegeei'' is an evergreen tree up to tall. Leaves are elliptical, not lobed, the blades up to long and tapering at both ends, sometimes with no teeth on the edge but sometimes with a few pointed teeth. Its habitat is restricted to stream-side locations. The species is listed as endangered by the IUCN Red List and threatened by long-term climatic drying and habitat loss Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby .... References External link The mystery of Mexico's vanishing stream oaks BBC Future brandegeei Endem ...

Quercus Sagraeana
''Quercus sagraeana'', the Cuban oak, is a medium-sized evergreen tree native to western Cuba in the Cuban pine forests ecoregion. It is the only oak native to the Caribbean. Nomenclature The Cuban oak was first described by Nuttall (1842) as ''Quercus sagraeana'' based on the specimen collected by Ramón de la Sagra. Using the same specimen, but apparently unaware of the original name, Richard (1853) named the Cuban oak ''Q. cubana''. Trelease (1924) did not view ''Q. sagraeana'' as a species in its own right but as a variety of '' Q. virginiana''. He proposed the name ''Q. virginiana'' var. ''sagraeana''. Muller (1961) renamed it ''Q. oleoides'' var. ''sagraeana'', hypothesizing that the Cuban oak population was a subspecies of '' Q. oleoides'', originating from the Yucatán region of Mexico, but with introgression from '' Q. geminata'' coming from Florida. He considered the morphologically variable Cuban population a hybrid swarm that h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quercus
An oak is a tree or shrub in the genus ''Quercus'' (; Latin "oak tree") of the beech family, Fagaceae. There are approximately 500 extant species of oaks. The common name "oak" also appears in the names of species in related genera, notably '' Lithocarpus'' (stone oaks), as well as in those of unrelated species such as ''Grevillea robusta'' (silky oaks) and the Casuarinaceae (she-oaks). The genus ''Quercus'' is native to the Northern Hemisphere, and includes deciduous and evergreen species extending from cool temperate to tropical latitudes in the Americas, Asia, Europe, and North Africa. North America has the largest number of oak species, with approximately 160 species in Mexico of which 109 are endemic and about 90 in the United States. The second greatest area of oak diversity is China, with approximately 100 species. Description Oaks have spirally arranged leaves, with lobate margins in many species; some have serrated leaves or entire leaves with smooth margins. ...

Quercus Oleoides
''Quercus oleoides'', with Spanish common names encina or encino, is a Mesoamerican species of oak in the live oak group (''Quercus'' sect. ''Virentes''). It grows in dry forests and pastureland of eastern and southern Mexico and much of Central America, from Guanacaste Province in Costa Rica north as far as the State of Tamaulipas in northeastern Mexico. ''Quercus oleoides'' is a slow-growing tree, reaching in height. Its pale gray leaves are evergreen, thick, hard, long, wide, oblong or elliptic. It flowers from December through May, with male catkin A catkin or ament is a slim, cylindrical flower cluster (a spike), with inconspicuous or no petals, usually wind-pollinated (anemophilous) but sometimes insect-pollinated (as in ''Salix''). They contain many, usually unisexual flowers, arranged cl ...s that are long, and female catkins that are long, containing one to six flowers, each about 7 mm long. Its wood is extremely heavy with intercrossed grains; the sapwood i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quercus Fusiformis
''Quercus fusiformis'' (also often referred to as ''Q. virginiana'' var. ''fusiformis''), commonly known as escarpment live oak, plateau live oak, plateau oak, or Texas live oak, is an evergreen or nearly evergreen tree. Its native range includes the Quartz Mountains and Wichita Mountains in southwestern Oklahoma, through Texas, to the Mexican states of Coahuila, Tamaulipas, and Nuevo León. ''Quercus fusiformis'' is an evergreen tree in the white oak section of the genus ''Quercus''. It is distinguished from ''Quercus virginiana'' (southern live oak) most easily by the acorns, which are slightly larger and with a more pointed apex. It is also a smaller tree, not exceeding in trunk diametercompared to 2.5 m (75 in) in diameter in southern live oakwith more erect branching and a less wide crown. Like ''Q. virginiana'', its magnificent, stately form and unparalleled longevity has endeared it to generations of residents throughout its native range. Its low hanging branches ...

Live Oak
Live oak or evergreen oak is any of a number of oaks in several different sections of the genus ''Quercus'' that share the characteristic of evergreen foliage. These oaks are not more closely related to each other than they are to other oaks. The name ''live oak'' comes from the fact that evergreen oaks remain green and "live" throughout winter, when other oaks are dormant and leafless. The name is used mainly in North America, where evergreen oaks are widespread in warmer areas along the Atlantic coast from southeast Virginia to Florida, west along the Gulf Coast to Louisiana and Mexico, and across the southwest to California. Evergreen oak species are also common in parts of southern Europe and south Asia, and are included in this list for the sake of completeness. These species, although not having "live" in their common names in their countries of origin, are colloquially called live oaks when cultivated in North America. When the term live oak is used in a specific rathe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quercus Virginiana
''Quercus virginiana'', also known as the southern live oak, is an evergreen oak tree endemic to the Southeastern United States. Though many other species are loosely called live oak, the southern live oak is particularly iconic of the Old South. Many very large and old specimens of live oak can be found today in the Deep South region of the United States. Description Although live oaks retain their leaves nearly year-round, they are not true evergreens. Live oaks drop their leaves immediately before new leaves emerge in the spring. Occasionally, Senescence, senescing leaves may turn yellow or contain brown spots in the winter, leading to the mistaken belief that the tree has oak wilt, whose symptoms typically occur in the summer. A live oak's defoliation may occur sooner in marginal climates or in dry or cold winters. The Bark (botany), bark is dark, thick, and furrowed longitudinally. The leaves are stiff and leathery, with the tops shiny dark green and the bottoms pale gra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quercus Minima
''Quercus minima'', the dwarf live oak or minimal oak, is a North American species of shrubs in the beech family. It is native to the southeastern United States. ''Quercus minima'' is an evergreen or semi-evergreen shrub rarely more than tall, reproducing by seed and also by means of underground rhizomes. It commonly forms extensive cloned colonies with many stems, many of them unbranched. The leaves are alternate, up to long, and toothless or with irregular teeth or lobes. The lobes, when present, are usually spine-tipped. The leaves are retained through the winter, dropping just before or as new growth resumes in late winter or early spring. ''Quercus minima'' is native to the coastal plain of the southeastern United States, primarily in Florida but extending from there to the Carolinas and eastern Louisiana. There are reports of the species also growing in Texas, but these populations appear to belong to other taxa. References {{Taxonbar, from=Q3827372 minima In ...
