Bigleaf Magnolia
''Magnolia macrophylla'', the bigleaf magnolia, is a deciduous magnolia native to the southeastern United States and eastern Mexico. This species boasts the largest simple leaf and single flower of any native plant in North America. Classification ''Magnolia macrophylla'' has three subspecies; some botanists treat these plants as three separate species: *''Magnolia macrophylla'' subsp. ''macrophylla''. Bigleaf magnolia. Southeastern United States. Secure. Tree to 65-foot; leaves 20-35 inch long, fruit 1.5–4 inch long with more than 50 carpels. *''Magnolia macrophylla'' subsp. ''ashei'' (Wetherby) Spongberg. Ashe magnolia. Northwest Florida. Shrub or small tree to 40-foot; leaves 10–23 inch long, fruit 1.5–2.3 inch long with less than 50 carpels. Considered by some botanists to be a distinct species, ''Magnolia ashei.'' *''Magnolia macrophylla'' subsp. ''dealbata'' (Zuccarini) J. D. Tobe.

André Michaux
André Michaux (' → ahn- mee-; sometimes Anglicisation, anglicised as Andrew Michaud; 8 March 174611 October 1802) was a French botanist and explorer. He is most noted for his study of North American flora. In addition Michaux collected specimens in England, Spain, France, and even Persia. His work was part of a larger European effort to gather knowledge about the natural world. Michaux's contributions include ''Histoire des chênes de l'Amérique'' (1801; "The Oaks of North America") and ''Flora Boreali-Americana'' (1803; "The Flora of North America") which continued to be botanical references well into the 19th century. His son, François André Michaux, also became an authoritative botanist. Biography Michaux was born in Satory, part of Versailles (city), Versailles, Yvelines, where his father managed farmland on the king's estate. Michaux was trained in the agricultural sciences in anticipation of his one-day assuming his father's duties, and received a basic classical 18 ...

Population Density
Population density (in agriculture: Standing stock (other), standing stock or plant density) is a measurement of population per unit land area. It is mostly applied to humans, but sometimes to other living organisms too. It is a key geographical term.Matt RosenberPopulation Density Geography.about.com. March 2, 2011. Retrieved on December 10, 2011. Biological population densities Population density is population divided by total land area, sometimes including seas and oceans, as appropriate. Low densities may cause an extinction vortex and further reduce fertility. This is called the Allee effect after the scientist who identified it. Examples of the causes of reduced fertility in low population densities are: * Increased problems with locating sexual mates * Increased inbreeding Human densities Population density is the number of people per unit of area, usually transcribed as "per square kilometre" or square mile, and which may include or exclude, for example, ar ...

Magnolia Acuminata
''Magnolia acuminata'', commonly called the cucumber tree (often spelled as a single word "cucumbertree"), cucumber magnolia or blue magnolia, is one of the largest magnolias, and one of the cold-hardiest. It is a large forest tree of the Eastern United States and Southern Ontario in Canada. It is a tree that tends to occur singly as scattered specimens, rather than in groves.Sternberg, G., & Wilson, J. (2004). Native Trees for North American Landscapes. Portland, Oregon:Timber Press The cucumber tree is native primarily within the Appalachian belt, including the Allegheny Plateau and Cumberland Plateau, up to western Pennsylvania and New York. There are also numerous disconnected outlying populations through much of the southeastern U.S., and a few small populations in Southern Ontario. In Canada, the cucumber tree is listed as an endangered species and is protected under the Canadian Species at Risk Act.White, D.J. (2000). Update COSEWIC Status Report on the Cucumber Tree ...

Diet (nutrition)
In nutrition, diet is the sum of food consumed by a person or other organism. The word diet often implies the use of specific intake of nutrition for #Health, health or #Weight management, weight-management reasons (with the two often being related). Although humans are omnivores, each culture and each person holds some food preferences or some food taboos. This may be due to personal tastes or ethical reasons. Individual dietary choices may be more or less healthy. Complete nutrition requires ingestion and absorption of vitamins, Dietary mineral, minerals, essential amino acids from protein and essential fatty acids from fat-containing food, also food energy in the form of carbohydrate, protein, and fat. Dietary habits and choices play a significant role in the quality of life, health and longevity. Health A healthy diet can improve and maintain health, which can include aspects of mental and physical health. Specific diets, such as the DASH diet, can be used in treatment ...

Fruit
In botany, a fruit is the seed-bearing structure in flowering plants (angiosperms) that is formed from the ovary after flowering. Fruits are the means by which angiosperms disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and other animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; humans, and many other animals, have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings. In common language and culinary usage, ''fruit'' normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet (or sour) and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term ''fruit'' als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torreya Taxifolia
''Torreya taxifolia'', commonly known as Florida torreya or stinking-cedar, but also sometimes as Florida nutmeg or gopher wood, is an endangered canopy (biology), subcanopy tree of the yew Family (biology), family, Taxaceae. It is native to only a small glacial refugium in the southeastern United States, at the state border region of northern Florida and southwestern Georgia (U.S. state), Georgia. Species discovery In 1821, colonial control of Spanish Florida shifted from Spain to the United States through the Adams–Onís Treaty, Adams-Onis Treaty. American settlers, including plantation owners and their slaves, began to move into the Florida Territory, exacerbating the Seminole Wars, on-going conflict with the refugee Red Sticks, Red Stick Creek and their allies from the Creek War and the emigrant population of Seminole, Seminoles and Maroons. One such plantation owner was the patriarch of the Croom family, who in 1826 purchased land around the town of Tallahassee. When he d ...

Taxus Floridana
''Taxus floridana'', the Florida yew, is a species of yew, endemic to a small area of the Apalachicola River.

Shrub
A shrub or bush is a small to medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple Plant stem, stems and shorter height, less than tall. Small shrubs, less than tall are sometimes termed as subshrubs. Many botany, botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some define a shrub as less than and a tree as over 6 m. Others use as the cutoff point for classification. Many trees do not reach this mature height because of hostile, less than ideal growing conditions, and resemble shrub-sized plants. Others in such species have the potential to grow taller in ideal conditions. For longevity, most shrubs are classified between Perennial plant, perennials and trees. Some only last about five years in good conditions. Others, usually larger and more woody, live beyond ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnolia Fraseri
''Magnolia fraseri'', commonly known as Fraser magnolia, mountain magnolia, earleaf cucumbertree, or mountain-oread, is a species of magnolia native to the southeastern United States in the southern Appalachian Mountains and adjacent Atlantic and Gulf Coastal Plain from West Virginia to northern Florida and to eastern Texas. The Appalachian plants are classified as ''Magnolia fraseri'' var. ''fraseri,'' and the more coastal plants as ''M. fraseri'' var. ''pyramidata.''
