Quercus Acerifolia
''Quercus acerifolia'' (also called maple-leaf oak) is a rare North American species of oak in the red oak section of ''Quercus'' (known as ''Lobatae''). It is endemic to just four locations within the Ouachita Mountains of the State of Arkansas. The tree sometimes reaches a height of 15 meters (50 feet). The venation of the leaves shows them to be technically pinnately five-lobed but with the two middle lobes larger than the other three. This makes the leaves appear palmately lobed at first glance, similar to many maple leaves. The epithet ''acerifolia'' means "maple-leaved." The species is threatened by 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 ... throughout its fragmented range. Groves of the tree are under cultivation in several locations, notably Steph ...

Ernest Jesse Palmer
Ernest Jesse Palmer (born April 8, 1875; died February 25, 1962) was a “collector-botanist” botanical taxonomist and plant collector. He began collecting in 1901, then collected professionally for the Missouri Botanical Garden starting in 1913 and for Harvard University's Arnold Arboretum from 1921, until 1948. He specialized in the genera ''Crataegus'' and ''Quercus''. Early life Ernest Jesse Palmer was born in Leicester, England on April 8, 1875 to Anna Windle Palmer and Amos Palmer. The family moved to west central Missouri when he was just three years old, then again in 1891 to Webb City, Missouri. Throughout his childhood his parents encouraged his interest in natural history. Career Palmer became his family’s main support at the age of eleven after his father lost his ability to work. He worked several jobs including deliveries via his horse and cart, and later bookkeeping for a local oil company, Waters-Pierce Oil Company. Meanwhile he continued his interests in nat ...

Stephens Lake Park
Stephens Lake Park is a park located in Columbia, Missouri, dating back to the early 19th century. Today it serves as an arboretum with a lake, and a park spanning 116 acres. It is often used as a live music venue. History In 1818, a man by the name David Gordon built a cabin on the area that would become the park. In 1823, The David Gordon House and Collins Log Cabin were built using slave labor. After construction of the manor was complete, the Gordons turned their cabin into slave quarters. The area was owned by the Gordon family for over a century. Then in 1926, the family sold the land to Stephens College. According to a news article from KRCG, someone purposely set David Gordon House on fire on November 9, 1998. The city of Columbia later purchased the park. The park was reopened in 2001. An amphitheatre in the park was opened on June 26, 2010. Discovery Garden The park contains a garden called Darwin and Axie Hindman Discovery Garden, it was built to honor Da ...

Plants Described In 1927
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have los ...

Trees Of The United States
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typicall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Flora Of The United States
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...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 mar ...

Columbia, Missouri
Columbia is a city in the U.S. state of Missouri. It is the county seat of Boone County and home to the University of Missouri. Founded in 1821, it is the principal city of the five-county Columbia metropolitan area. It is Missouri's fourth most-populous and fastest growing city, with an estimated 126,254 residents in 2020. As a Midwestern college town, Columbia has a reputation for progressive politics, persuasive journalism, and public art. The tripartite establishment of Stephens College (1833), the University of Missouri (1839), and Columbia College (1851), which surround the city's Downtown to the east, south, and north, has made the city a center of learning. At its center is 8th Street (also known as the Avenue of the Columns), which connects Francis Quadrangle and Jesse Hall to the Boone County Courthouse and the City Hall. Originally an agricultural town, education is now Columbia's primary economic concern, with secondary interests in the healthcare, insuranc ...

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 reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leaves
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper (adaxial) and lower (abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs light en ...
