Quercus Arkansana
''Quercus arkansana'', the Arkansas oak, is a species of oak tree. It is native to the southeastern United States (eastern Texas, southern Arkansas, Louisiana, Mississippi, Alabama, Georgia (U.S. state), Georgia, and the Florida Panhandle). It is threatened by use of its habitat for pine plantations, clearing of land, and diebacks that may be caused by drought. Description ''Quercus arkansana'' is a deciduous tree growing up to tall. The Bark (botany), bark is black. The leaves are sometimes unlobed and sometimes with 2 or 3 shallow lobes. Habitat ''Quercus arkansana'' is shade-loving tree that grows in the understories of Mesic habitat, mesic pine forests and southern hardwood stands, and it is frequently reported from sandhills, the upper portions of ravines, steepheads, and above the heads of small streams. It is rarely a dominant component of the vegetation, except for a few places in Arkansas and Florida where it is found in large stands. It grows alongside ''Pinus taeda'', ...

Charles Sprague Sargent
Charles Sprague Sargent (April 24, 1841 – March 22, 1927) was an American botanist. He was appointed in 1872 as the first director of Harvard University's Arnold Arboretum in Boston, Massachusetts, and held the post until his death. He published several works of botany. The standard botanical author abbreviation Sarg. is applied to plants he identified. Early life Sargent was the second son of Henrietta (Gray) and Ignatius Sargent, a Boston merchant and banker who grew wealthy on railroad investments. He grew up on his father's 130-acre (53-ha) estate in Brookline, Massachusetts. He attended Harvard College, where he graduated in Biology in the class of 1862. Sargent enlisted in the Union Army later that year, saw service in Louisiana during the American Civil War, and was mustered out in 1865. He traveled in Europe and Asia for three years. Career Having returned to his family's Brookline estate, "Holmlea", Sargent took over its management as a horticulturist, influence ...

Pinus Echinata
''Pinus echinata'', the shortleaf pine, is a species of pine native to the southeastern United States. Description The tree is variable in form, sometimes straight, sometimes crooked, with an irregular crown. The tree reaches heights of with a trunk diameter of . The leaves are needle-like, in fascicles (bundles) of two and three mixed together, and from long. The cones are long, with thin scales with a transverse keel and a short prickle. They open at maturity but are persistent. Shortleaf pine seedlings develop a persistent J-shaped crook near the ground surface. Axillary and other buds form near the crook and initiate growth if the upper stem is killed by fire or is severed. The bark has resin pockets, which form small depressions, less than in diameter. This feature can be used to distinguish ''P. echinata'' from all other ''Pinus'' species within its native range. Taxonomy The Latin specific epithet of ''echinata'' refers to hedgehog, from ''echinus''. Di ... [...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 Falcata
''Quercus falcata'', also called southern red oak, spanish oak, bottomland red oak or three-lobed red oak is an oak (part of the genus ''Quercus''). Native to the southeastern United States, it gets its name the "Spanish Oak" as these are the areas of early Spanish colonies, whilst "southern red oak" comes from both its range and leaf color during late summer and fall. The southern red oak is a deciduous angiosperm, so has leaves that die after each growing period and come back in the next period of growth. Description ''Quercus falcata'' is a medium to large-sized deciduous tree tall, with a few forest grown specimens on highly productive sites reaching , with a trunk up to in diameter, the crown with a broad, round-topped head. The leaves are long and wide, with 3 to 5 sharply pointed, often curved, bristle-tipped lobes, the central lobe long and narrow; the small number of long, narrow lobes is diagnostic, readily distinguishing southern red oak from other red oaks.

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diospyros Virginiana
''Diospyros virginiana'' is a persimmon species commonly called the American persimmon, common persimmon, eastern persimmon, simmon, possumwood, possum apples, or sugar plum. It ranges from southern Connecticut to Florida, and west to Texas, Louisiana, Oklahoma, Kansas, and Iowa. The tree grows wild but has been cultivated for its fruit and wood since prehistoric times by Native Americans. ''Diospyros virginiana'' grows to , in well-drained soil. The tree is typically dioecious, so one must have both male and female plants to obtain fruit. Most cultivars are parthenocarpic (setting seedless fruit without pollination). The fragrant flowers are pollinated by insects and wind. Fruiting typically begins when the tree is about 6 years old. The fruit is round or oval and usually orange-yellow, sometimes bluish, and from in diameter. Both the tree and the fruit are referred to as persimmons, with the latter appearing in desserts and cuisine in the U.S. South and Midwest. Commerc ...

Nyssa Sylvatica
''Nyssa sylvatica'', commonly known as tupelo, black tupelo, black gum or sour gum, is a medium-sized deciduous tree native to eastern North America from the coastal Northeastern United States and southern Ontario south to central Florida and eastern Texas, as well as Mexico. Names ''Nyssa sylvatica'' genus name, ''Nyssa'', refers to a Greek water nymph; the species epithet ''sylvatica'' refers to its woodland habitat. The species' common name, tupelo, is of Native American origin, coming from the Creek words ''ito'' "tree" and ''opilwa'' "swamp"; it was in use by the mid-18th century. While these trees are often known as simply "tupelo", the fuller name, black tupelo, helps distinguish it from the other species of the tupelo genus ''Nyssa'', some of which have overlapping ranges, such as water tupelo (''N. aquatica'') and swamp tupelo (''N. biflora''). The name "tupelo" is used primarily in the American South; northward and in Appalachia, the tree is more commonly called t ...
