Zanthoxylum Nitidum
''Zanthoxylum nitidum'', commonly known as shiny-leaf prickly-ash, tez-mui (in Assamese) or liang mian zhen (in China), is a species of flowering plant in the family Rutaceae. It is a woody climber with prickles on the branchlets, thick, cone-shaped spines on the trunk and older branches, pinnate leaves with five to nine leaflets, and panicles or racemes of white to pale yellow, male or female flowers in leaf axils and on the ends of branchlets. Description ''Zanthoxylum nitidum'' is a woody climber with curved prickles on the branchlets and thick, cone-shaped spines on the trunk and older branches. The leaves are pinnate, long with five to nine egg-shaped to elliptical leaflets. The leaflets are long and wide, the side leaflets sessile or on a petiolule up to long and the end leaflet on a petiolule long. The flowers are arranged in leaf axils or on the ends of branchlets in panicles or racemes up to long, each flower on a pedicel long. The four sepals are long and t ...

William Roxburgh
William Roxburgh FRSE FRCPE FLS (3/29 June 1751 – 18 February 1815) was a Scottish surgeon and botanist who worked extensively in India, describing species and working on economic botany. He is known as the founding father of Indian botany. He published numerous works on Indian botany, illustrated by careful drawings made by Indian artists and accompanied by taxonomic descriptions of many plant species. Apart from the numerous species that he named, many species were named in his honour by his collaborators. Early life He was born on 3 June 1751 on the Underwood estate near Craigie in Ayrshire and christened on 29 June 1751 at the nearby church at Symington. His father may have worked in the Underwood estate or he may have been the illegitimate son of a well-connected family. His early education was at Underwood parish school perhaps also with some time at Symington parish school, and he probably also had private tutoring in Latin, as demonstrated by his letters and some d ...

Gynoecium
Gynoecium (; ) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds. The gynoecium is the innermost whorl of a flower; it consists of (one or more) ''pistils'' and is typically surrounded by the pollen-producing reproductive organs, the stamens, collectively called the androecium. The gynoecium is often referred to as the "female" portion of the flower, although rather than directly producing female gametes (i.e. egg cells), the gynoecium produces megaspores, each of which develops into a female gametophyte which then produces egg cells. The term gynoecium is also used by botanists to refer to a cluster of archegonia and any associated modified leaves or stems present on a gametophyte shoot in mosses, liverworts, and hornworts. The corresponding terms for the male parts of those plants are clusters of antheridia within the androecium. Flowers that bear a gynoecium but no stamens are cal ...

Traditional Medicine
Traditional medicine (also known as indigenous medicine or folk medicine) comprises medical aspects of traditional knowledge that developed over generations within the folk beliefs of various societies, including indigenous peoples, before the era of modern medicine. The World Health Organization (WHO) defines traditional medicine as "the sum total of the knowledge, skills, and practices based on the theories, beliefs, and experiences indigenous to different cultures, whether explicable or not, used in the maintenance of health as well as in the prevention, diagnosis, improvement or treatment of physical and mental illness". Traditional medicine is often contrasted with scientific medicine. In some Asian and African countries, up to 80% of the population relies on traditional medicine for their primary health care needs. When adopted outside its traditional culture, traditional medicine is often considered a form of alternative medicine. Practices known as traditional medici ...

Condiment
A condiment is a preparation that is added to food, typically after cooking, to impart a specific flavor, to enhance the flavor, or to complement the dish. A table condiment or table sauce is more specifically a condiment that is served separately from the food and is added to taste by the diner. Condiments are sometimes added prior to serving, for example, in a sandwich made with ketchup, mustard or mayonnaise. Some condiments are used during cooking to add flavor or texture: barbecue sauce, compound butter, teriyaki sauce, soy sauce, Marmite and sour cream are examples. Many condiments, such as mustard or ketchup, are available in single-serving packets, commonly when supplied with take-out or fast food meals. Definition The exact definition of a condiment varies. Some definitions encompass spices and herbs, including salt and pepper, using the term interchangeably with ''seasoning''. Others restrict the definition to include only "prepared food compound containing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Piscicide
A piscicide is a chemical substance which is poisonous to fish. The primary use for piscicides is to eliminate a dominant species of fish in a body of water, as the first step in attempting to populate the body of water with a different fish. They are also used to combat parasitic and invasive species of fish. Examples of piscicides include rotenone, saponins, TFM, niclosamide and Antimycin A (Fintrol).Susan J. Clearwater, Chris W. Hickey, Michael L. Martin Overview of potential piscicides and molluscicides for controlling aquatic pest species in New Zealand' Science & Technical Publishing 2008 Plant-based piscicides Historically, fishing techniques of indigenous people around the world have frequently included the use of plant-based piscicides.

Insecticide
Insecticides are substances used to kill insects. They include ovicides and larvicides used against insect eggs and larvae, respectively. Insecticides are used in agriculture, medicine, industry and by consumers. Insecticides are claimed to be a major factor behind the increase in the 20th-century's agricultural productivity. Nearly all insecticides have the potential to significantly alter ecosystems; many are toxic to humans and/or animals; some become concentrated as they spread along the food chain. Insecticides can be classified into two major groups: systemic insecticides, which have residual or long term activity; and contact insecticides, which have no residual activity. The mode of action describes how the pesticide kills or inactivates a pest. It provides another way of classifying insecticides. Mode of action can be important in understanding whether an insecticide will be toxic to unrelated species, such as fish, birds and mammals. Insecticides may be repellen ...

Daintree River
The Daintree River is a river that rises in the Daintree Rainforest near Cape Tribulation in Far North Queensland, Australia. The river is located about northwest of Cairns in the UNESCO World Heritagelisted Wet Tropics of Queensland. The area is now primarily a tourist attraction. Course and features The river rises on the slopes of the Great Dividing Range within the Daintree National Park below Kalkajaka at an elevation of . The river flows in highly meandering course generally north, then east, then south and then east, through the rainforest where the water is fresh. At this convergence point, an abundance of wildlife congregate, particularly fish. The river is joined by two minor tributaries before flowing through the Cairns Marine Park through thick mangrove swamps where the water is highly saline; and then empties into the Coral Sea, north of . The mouth of the Daintree River opens onto a giant sandbar that shifts with each changing tide. The river descends over its ...

Prodromus Systematis Naturalis Regni Vegetabilis
''Prodromus Systematis Naturalis Regni Vegetabilis'' (1824–1873), also known by its standard botanical abbreviation ''Prodr. (DC.)'', is a 17-volume treatise on botany initiated by Augustin Pyramus de Candolle. De Candolle intended it as a summary of all known seed plants, encompassing taxonomy, ecology, evolution and biogeography. He authored seven volumes between 1824 and 1839, but died in 1841. His son, Alphonse de Candolle, then took up the work, editing a further ten volumes, with contributions from a range of authors. Volume 17 was published in October 1873. The fourth and final part of the index came out in 1874. The ''Prodromus'' remained incomplete, dealing only with dicotyledons. In the ''Prodromus'', De Candolle further developed his concept of families. Note that this system was published well before there were internationally accepted rules for botanical nomenclature. Here, a family is indicated as "ordo". Terminations for families were not what they are now. Neithe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
