Melochia Umbellata
''Melochia umbellata'' is a species of flowering plant in the mallow family, Malvaceae. Its specific name (botany), specific epithet comes from the Latin ''umbellatus'' (umbel-like), referring to the inflorescence. Description ''Melochia umbellata'' is a shrub or small tree, growing to 2–15 m in height. It grows rapidly and is able to colonise disturbed land.Starr et al. (2003). It has large, broadly ovate, leaf, leaves 90–300 mm long. The flowers are usually pale pink to red. The seeds are winged and wind-dispersed. Distribution and habitat The plant is native to a region extending from India eastwards through Southeast Asia to north-western Australia and New Guinea.

Martinus Houttuyn
Maarten Houttuyn or Houttuijn (1720 – 2 May 1798) Latinised as Martinus Houttuyn, was a Dutch naturalist. Houttuyn was born in Hoorn, studied medicine in Leiden and moved to Amsterdam in 1753. He published many books on natural history, e.g. ''Natuurlyke Historie of uitvoerige Beschryving der Dieren, Planten en Mineraalen, volgens het Samenstel van den Heer Linnaeus'', in 37 volumes (1761-1773), following Carl Linnaeus' division into the animal kingdom, the plant kingdom, and the mineral kingdom. His areas of interest encompassed Pteridophytes, Bryophytes and Spermatophytes. He died in Amsterdam. In botanical nomenclature, the standard author abbreviation ''Houtt.'' is applied to plants described by him. He is commemorated by the genus ''Houttuynia'', a member of the Saururaceae from China and Japan. Martinus Houttuyn was the co-writer of the volumes 2, 3, 4 and 5 of '' Nederlandsche Vogelen''.His name appears on the title pages ovol 2 an of ''Nederlandsche Vogelen''. ...

Shade Tree
A shade tree is a large tree whose primary role is to provide shade in the surrounding environment due to its spreading canopy (forest), canopy and crown (botany), crown, where it may give shelter from sunlight in the heat of the summer for people who seek recreational needs in urban parks and house Front yard, yards, and thus, also protecting them from the sun's harmful UV rays and sunburns. Therefore, some shade trees may be grown specifically for the comfort of the population due to their convenient shelter. Furthermore, shade trees are also effective in reducing the energy used in cooling homes. Popular shade trees Some of the most popular shade trees in temperate countries are oaks, Platanaceae, plane trees, willows, birches, beeches, maples, ash (tree), ashes, Tilia, lindens, and elms. In subtropical countries like Australia and India, figs are popular choices as shade trees. In tropical countries, trees such as some Erythrina and African tulip tree species are often plan ...

Flora Of Tropical Asia
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 Phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1913
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 lo ...

Australian Biological Resources Study
Australian Biological Resources Study (ABRS) is a project undertaken by Parks Australia Division of Australia's Department of the Environment, Water, Heritage and the Arts (DEWHA). Background ABRS was founded in 1973 from the recommendations of a 1972 Senate Select Committee report on Wildlife Conservation. Its purpose is to collate from the many libraries, museums and other collections the taxonomy of Australia's estimated 2 million species of flora and fauna, including aquatic species. These represent almost 20% of the earth's biodiversity, 80% of which are unique to Australia. ABRS has undertaken active funding for taxonomic research of Australia's biodiversity and is internationally recognised for its extensive data bases and publications. Publications The most important outputs of the ABRS has been the publication of the multi-volume ''Flora of Australia'' and '' Fauna of Australia'' series. Other output includes ''The Banksia Atlas'' and the "Platypus" database pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reforestation
Reforestation (occasionally, reafforestation) is the natural or intentional restocking of existing forests and woodlands (forestation) that have been depleted, usually through deforestation, but also after clearcutting. Management A debated issue in managed reforestation is whether or not the succeeding forest will have the same biodiversity as the original forest. If the forest is replaced with only one species of tree and all other vegetation is prevented from growing back, a monoculture forest similar to agricultural crops would be the result. However, most reforestation involves the planting of different selections of seedlings taken from the area, often of multiple species. Another important factor is the natural regeneration of a wide variety of plant and animal species that can occur on a clear cut. In some areas the suppression of forest fires for hundreds of years has resulted in large single aged and single species forest stands. The logging of small clear cuts an ...

Weed
A weed is a plant considered undesirable in a particular situation, "a plant in the wrong place", or a plant growing where it is not wanted.Harlan, J. R., & deWet, J. M. (1965). Some thoughts about weeds. ''Economic botany'', ''19''(1), 16-24. This introduces the concept of humans and their goals in a particular setting.Holzner, W., & Numata, M. (Eds.). (2013). ''Biology and ecology of weeds'' (Vol. 2). Springer Science & Business Media. The concept of weeds is particularly significant in agriculture, where the aim is growing crops or pastures of a single species, or a mixture of a few desired species. In such environments, other plant species are considered undesirable and therefore a weed. Besides, some weeds have undesirable characteristics making them a plant pest in most human settings.Harlan, J. R., & deWet, J. M. (1965). Some thoughts about weeds.

Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...

Plantation
A plantation is an agricultural estate, generally centered on a plantation house, meant for farming that specializes in cash crops, usually mainly planted with a single crop, with perhaps ancillary areas for vegetables for eating and so on. The crops that are grown include cotton, coffee, tea, cocoa, sugar cane, opium, sisal, oil seeds, oil palms, fruits, rubber trees and forest trees. Protectionist policies and natural comparative advantage have sometimes contributed to determining where plantations are located. In modern use the term is usually taken to refer only to large-scale estates, but in earlier periods, before about 1800, it was the usual term for a farm of any size in the southern parts of British North America, with, as Noah Webster noted, "farm" becoming the usual term from about Maryland northwards. It was used in most British colonies, but very rarely in the United Kingdom itself in this sense. There, as also in America, it was used mainly for tree plantations, a ...
