Physaria Globosa
''Physaria globosa'' is a rare flowering plant in the mustard family commonly known as globe bladderpod, Short's bladderpod, and Lesquereux's mustard. It is endemic to the United States, where it is limited to Indiana, Kentucky, and Tennessee. It is a rare species throughout its range and in 2014 the U.S. Fish and Wildlife Service issued a final rule protecting it under the Endangered Species Act. Description ''Physaria globosa'' is a small plant covered with dense hairs giving it a grayish appearance. It produces yellow flowers in the spring, and its fruit is globe-shaped. Its preferred habitat is dry limestone cliffs, barrens, cedar glades, steep wooded slopes, and talus areas. Some have also been found in areas of deeper soil and roadsides. Conservation The population fluctuates year to year, but on average there are about 2000 living plants at any one time, divided among 33 known locations. Threats include forms of habitat degradation and destruction, including road construct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alliaria Petiolata
''Alliaria petiolata'', or garlic mustard, is a biennial flowering plant in the mustard family (Brassicaceae). It is native to Europe, western and central Asia, north-western Africa, Morocco, Iberia and the British Isles, north to northern Scandinavia, and east to northern Pakistan and Xinjiang in western China. In the first year of growth, plants form clumps of round, slightly wrinkled leaves, that when crushed smell like garlic. The plants flower in spring of the next year, producing cross shaped white flowers in dense clusters. As the flowering stems bloom they elongate into a spike-like shape. When flowering is complete, plants produce upright fruits that release seeds in mid-summer. Plants are often found growing along the margins of hedges, giving rise to the old British folk name of jack-by-the-hedge. Other common names include: garlic mustard, garlic root, hedge garlic, sauce-alone, jack-in-the-bush, penny hedge and poor man's mustard. The genus name ''Alliaria'', "res ...

Flora Of Tennessee
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) 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, 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 indiscriminately.Thurmann, J. (1849). ''Essai de Phyt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Physaria
''Physaria'' is a genus of flowering plants in the family Brassicaceae. Many species are known generally as twinpods, bladderpods, or lesquerella. They are native to the Americas, with many species endemic to western North America. They are densely hairy annual and perennial herbs often growing prostrate or decumbent, along the ground in patches or clumps. They bear inflorescences of bright yellow flowers. The fruit is often notched deeply, dividing into twin sections, giving the genus its common name. Bladderpod oil is extracted from the seeds of ''Physaria fendleri'' and certain other species in the genus. U.S. Fish and Wildlife Service: Missouri Bladderpod 5-Year Review (2008) Due to the presence of both annual and perennial herbaceous members, this genus has been used as a model for allocation pattern comparisons ...

Local Extinction
Local extinction, also known as extirpation, refers to a species (or other taxon) of plant or animal that ceases to exist in a chosen geographic area of study, though it still exists elsewhere. Local extinctions are contrasted with global extinctions. Local extinctions mark a change in the ecology of an area. In recent times, local extinction has sometimes been followed by a replacement of the species taken from other locations; wolf reintroduction is an example of this. The term "local extinction" is highly vernacular. The more proper biological term is ''extirpation''. Discussion Glaciation can lead to local extinction. This was the case during the Pleistocene glaciation event in North America. During this period, most of the native North American species of earthworm were killed in places covered by glaciation. This left them open for colonization by European earthworms brought over in soil from Europe. Species naturally become extirpated from islands over time. The number ...

Rosa Multiflora
''Rosa multiflora'' — ( syn. ''Rosa polyantha'') is a species of rose known commonly as multiflora rose, baby rose, Japanese rose, many-flowered rose, seven-sisters rose, Eijitsu rose and rambler rose. It is native to eastern Asia, in China, Japan, and Korea. It should not be confused with ''Rosa rugosa'', which is also known as "Japanese rose", or with polyantha roses which are garden cultivars derived from hybrids of ''R. multiflora''. It was introduced to North America, where it is regarded as an invasive species. Description It is a scrambling shrub climbing over other plants to a height of , with stout stems with recurved prickles (sometimes absent). The leaves are long, compound, with 5–9 leaflets and feathered stipules. The flowers are produced in large corymbs, each flower small, diameter, white or pink, borne in early summer. The hips are reddish to purple, diameter. Two varieties are accepted by the ''Flora of China'': * ''Rosa multiflora'' var. ''multifl ...

Festuca Pratensis
''Festuca pratensis'', the meadow fescue, is a perennial species of grass, which is often used as an ornamental grass in gardens, and is also an important forage crop. It grows in meadows, roadsides, old pastures, and riversides on moist, rich soils, especially on loamy and heavy soils. It is a tall, tufted grass similar to the tall fescue, ''Festuca arundinacea''. Tall fescue differs by having minute hairs on the auricles. It can hybridise with ''Lolium perenne'' and ''Lolium multiflorum''. Description It is a perennial bunchgrass, (i.e. grows in tufts), which grows , flowering from June until August. The panicles are green to purplish. The spikelets have 5 to 14 flowers. It has a short, blunt ligule A ligule (from "strap", variant of ''lingula'', from ''lingua'' "tongue") is a thin outgrowth at the junction of leaf and leafstalk of many grasses (Poaceae) and sedges.

Melilotus Albus
''Melilotus albus'', known as honey clover, white melilot (UK), Bokhara clover (Australia), white sweetclover (USA), and sweet clover, is a nitrogen-fixing legume in the family Fabaceae. ''Melilotus albus'' is considered a valuable honey plant and source of nectar and is often grown for forage. Its characteristic sweet odor, intensified by drying, is derived from coumarin. ''Melilotus albus'' is of Eurasian origin but can now be found throughout the subtropical to temperate zones, especially in North America, and is common in sand dune, prairie, bunchgrass, meadow, and riparian habitats. This species is listed as an "exotic pest" in Tennessee, "ecologically invasive" in Wisconsin, and a "weed" in Kentucky and Quebec. Description ''Melilotus albus'' is an annual or biennial legume that can reach in height.Joseph M. DiTomaso and Evelyn A.

Trifolium Hybridum
''Trifolium hybridum'', the alsike clover, is a species of flowering plant in the pea family Fabaceae. The stalked, pale pink or whitish flower head grows from the leaf axils, and the trifoliate leaves are unmarked. The plant is up to tall, and is found in fields and on roadsides – it is also grown as fodder (hay or silage). The plant blooms from spring to autumn (April to October in the northern hemisphere). Originating in mainland Europe, it has become established as an introduced plant in the British Isles and throughout the temperate regions of the world. History Despite its scientific name, alsike clover is not of hybrid origin. The plant gets its common name from the town of Alsike in Sweden from which Linnaeus first described it. He thought it was a cross between white clover (''T. repens'') and red clover (''T. pratense''), but in this he was mistaken and it is a separate species.

Lonicera Japonica
''Lonicera japonica'', known as Japanese honeysuckle and golden-and-silver honeysuckle, is a species of honeysuckle native to eastern Asia. It is often grown as an ornamental plant, but has become an invasive species in a number of countries. Japanese honeysuckle is used in traditional Chinese medicine. Description ''Lonicera japonica'' is a twining vine able to climb up to high or more in trees, with opposite, simple oval leaves long and broad. When its stems are young, they are slightly red in color and may be fuzzy. Older stems are brown with peeling bark, and are often hollow on the inside. The flowers are double-tongued, opening white and fading to yellow, and sweetly vanilla scented. The fruit, which is produced in fall, is a black spherical berry diameter containing a few seeds. While the nectar from the flowers can be safely consumed by humans, all other parts of the plant have the potential to be toxic. Subspecies There are three subspecies of ''Lonicera japonica'' ...
