Lespedeza Virginica
''Lespedeza virginica'', known as slender bush clover or slender lespedeza, is a species of flowering plant native to much of the United States, as well as Ontario, Canada, and Nuevo León, Mexico. It is a member of the bean family, Fabaceae. Description ''Lespedeza virginica'' is an herbaceous, perennial legume. It can grow to be up to 2.5 feet tall. Slender bush clover has trifoliate compound leaves and slender primary petioles, with the stem covered in small white hairs. Its alternate leaves are dark green, though sometimes appear pale. The flowers are pink and have a broad upper petal with two side petals. Flowers produced are either cleistogamous or chasmogamous. Slender bush clover flowers from July to September and sets seed from September to October. ''L. virginica'' grows well in environments with full to partial sun and can grow successfully in rocky or sandy soils. It produces a taproot to assist in establishment.

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flora Of Eastern Canada
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous (ecology), indigenous) native plant, native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora (mythology), Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of The United States
The native flora of the United States includes about 17,000 species of vascular plants, plus tens of thousands of additional species of other plants and plant-like organisms such as algae, lichens and other fungi, and mosses. About 3,800 additional non-native species of vascular plants are recorded as established outside of cultivation in the U.S., as well as a much smaller number of non-native non-vascular plants and plant relatives. The United States possesses one of the most diverse temperate floras in the world, comparable only to that of China. Several biogeographic factors contribute to the richness and diversity of the U.S. flora. While most of the United States has a temperate climate, Alaska has vast arctic areas, the southern part of Florida is tropical, as well as Hawaii (including high mountains), and the U.S. territories in the Caribbean and the Pacific, and alpine summits are present on many western mountains, as well as a few in the Northeast.

Lespedeza
''Lespedeza'' is a genus of some 40 species (including nothospecies) of flowering plants in the pea family (Fabaceae), commonly known as bush clovers or (particularly East Asian species) Japanese clovers (''hagi''). The genus is native to warm temperate to subtropical regions of eastern North America, eastern and southern Asia and Australasia. These shrubby plants or trailing vines belong to the "typical" legumes (Faboideae), with the peas and beans, though they are part of another tribe (biology), tribe, the Desmodieae. Therein, they are treated as type genus of the smaller subtribe Lespedezinae, which unites the present genus and its presumed closest relatives, ''Campylotropis'' and ''Kummerowia''. Name of the plant According to American botanist Asa Gray (1810 – 1888), the ''Lespedeza'' owes its name to governor of East Florida Vicente Manuel de Céspedes (1784-1790; who, through a letter, allowed botanist André Michaux to explore East Florida in search of new species of pl ...

Crownvetch
''Securigera varia'' (synonym ''Coronilla varia''), commonly known as crownvetch or purple crown vetch, is a low-growing legume vine. It is native to Africa, Asia and Europe and is commonly used throughout the United States and Canada for erosion control, roadside planting and soil rehabilitation. It has become an invasive species in many states of the US. Crownvetch grows 1 to 2 feet tall and bears small clusters of 1/2-inch pink and white flowers from early summer to late fall. The variety Penngift produces mounds of pink flowers. Crownvetch is a tough, aggressive spreading plant that will crowd out its neighbors in a show garden but is well suited to a sunny bank, where it will grow for decades with little to no fertilizing, mowing, or weeding since the thick foliage prevents weeds from growing amid it.

Ojibway Prairie Complex
The Ojibway Prairie Complex is a 350-hectare complex of parks and nature reserves on the west side of Windsor, Ontario, Canada. It comprises Ojibway Park, Tallgrass Prairie Heritage Park, Black Oak Heritage Park, and the Spring Garden Natural Area, owned and managed by the City of Windsor, as well as Ojibway Prairie Provincial Park, owned and managed by Ontario Parks. Other natural areas are present adjacent to these parks that are not currently protected. The complex protects one of the largest remnants of tallgrass prairie and oak savannah in Ontario. These open habitats are present due to sandy soil over a bed of clay, which is less suitable for the growth of trees. The use of prescribed burns is important to manage these habitats. The complex is notable for its high diversity of plants and animals, including over 160 provincially rare species, more than any other site in Ontario. Several insect and plant species are not known from anywhere else in Ontario. Examples of prote ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species At Risk Act
The ''Species at Risk Act'' (SARA) (the ''Act'') is a piece of Canadian federal legislation which became law in Canada on December 12, 2002. It is designed to meet one of Canada's key commitments under the International Convention on Biological Diversity. The goal of the ''Act'' is to prevent wildlife species in Canada from disappearing by protecting endangered or threatened organisms and their habitats. It also manages species which are not yet threatened, but whose existence or habitat is in jeopardy. SARA defines a method to determine the steps that need to be taken in order to help protect existing relatively healthy environments, as well as recover threatened habitats, although timing and implementation of recovery plans have limitations. It identifies ways in which governments, organizations, and individuals can work together to preserve species at risk and establishes penalties for failure to obey the law. The ''Act'' designates COSEWIC, an independent committee of wildli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bobwhite Quail
The northern bobwhite (''Colinus virginianus''), also known as the Virginia quail or (in its home range) bobwhite quail, is a ground-dwelling bird native to Canada, the United States, Mexico, and Cuba, with introduced populations elsewhere in the Caribbean, Europe, and Asia. It is a member of the group of species known as New World quail (Odontophoridae). They were initially placed with the Old World quail in the pheasant family ( Phasianidae), but are not particularly closely related. The name "bobwhite" is an onomatopoeic derivation from its characteristic whistling call. Despite its secretive nature, the northern bobwhite is one of the most familiar quails in eastern North America, because it is frequently the only quail in its range. Habitat degradation has likely contributed to the northern bobwhite population in eastern North America declining by roughly 85% from 1966 to 2014. This population decline is apparently range-wide and continuing. There are 23 subspecies of nor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nathaniel Lord Britton
Nathaniel Lord Britton (January 15, 1859 – June 25, 1934) was an American botanist and taxonomist who co-founded the New York Botanical Garden in the Bronx, New York (state), New York. Early life Britton was born in New Dorp, Staten Island, New Dorp in Staten Island, New York to Jasper Alexander Hamilton Britton and Harriet Lord Turner. His parents wanted him to study religion, but he was attracted to nature study at an early age. He was a graduate of the School of Engineering and Applied Science (Columbia University), Columbia University School of Mines and afterwards taught geology and botany at Columbia University. He joined the Torrey Botanical Society, Torrey Botanical Club soon after graduation and was a member his entire life. He married Elizabeth Gertrude Britton, Elizabeth Gertrude Knight, a Bryophyte, bryologist, on August 27, 1885.

Taproot
A taproot is a large, central, and dominant root from which other roots sprout laterally. Typically a taproot is somewhat straight and very thick, is tapering in shape, and grows directly downward. In some plants, such as the carrot, the taproot is a storage organ so well developed that it has been cultivated as a vegetable. The taproot system contrasts with the adventitious or fibrous root system of plants with many branched roots, but many plants that grow a taproot during germination go on to develop branching root structures, although some that rely on the main root for storage may retain the dominant taproot for centuries, for example ''Welwitschia''.Taproot also store nutrition. Plants with taproots are often vegetables. Description Dicots, one of the two divisions of flowering plants (angiosperms), start with a taproot, which is one main root forming from the enlarging radicle of the seed. The tap root can be persistent throughout the life of the plant but is most oft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chasmogamous
Chasmogamy, is a plant reproductive mechanism in which pollination occurs in chasmogamous flowers. Chasmogamous flowers are commonly showy with open petals encircling exposed reproductive parts. Chasmogamous stems from Greek for "open marriage", named after the open arrangement of floral structures. Once chasmogamous flowers have reached maturity, they unfurl and their stamens and/or style are made available for pollination. Although some plant species possess self-fertilizing chasmogamous flowers, most chasmogamous flowers are cross-pollinated by biotic (e.g. insects) or abiotic (e.g. wind) agents. Chasmogamous flowers that are cross-pollinated have the advantage of sexual reproduction between two different parents, resulting in sexual recombination and genetically distinct seeds. These distinct seeds increase genetic diversity of the plant population and reduce inbreeding depression and deleterious alleles. Seeds produced by chasmogamous flowers that are cross-pollinated, may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
