Spenceria
''Spenceria ramalana'' is the lone species in the plant genus ''Spenceria'', known by two varieties. ''S. ramalana'' grows from 18–32 cm. tall, and puts out yellow flowers from July through August; bearing fruit (yellowish-brown achenes) from September to October. The Chinese name, ''ma ti huang'' ��蹄黄 can be translated to mean "yellow horseshoe". Etymology Henry Trimen, both the genus, and binomial authority of ''Spenceria'', and ''S. ramalana'', respectively, gave an explanation of how he arrived at these names: the genus name was given in honour of Trimen's friend, and fellow botanist, Spencer Moore, who was employed at the Kew Herbarium. Trimen thought about choosing a name commemorating the collector of the species, one Captain Gill, R.E., but decided against it, as there already was a genus ''Gilia'' (Polemoniaceae), and he wished to avoid, in his words, "the formation of another of precisely similar sound." As the species was collected from a mounta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spencer Le Marchant Moore
Spencer Le Marchant Moore (1 November 1850 – 14 March 1931) was an English botanist. Biography Moore was born in Hampstead. He worked at the Royal Botanic Gardens, Kew, from about 1870 to 1879, wrote a number of botanical papers, and then worked in an unofficial capacity at the Natural History Museum from 1896 until his death. He was involved in an expedition to remote parts of Western Australia Western Australia (WA) is the westernmost state of Australia.

Henry Trimen
Henry Trimen (26 October 1843 – 16 October 1896) was a British botanist who worked in Sri Lanka. He named several plants in the family Dipterocarpaceae. Life Trimen was born in Park Place, Paddington, London, England, the son of Richard and Marinne Trimen and the younger brother of entomologist Roland Trimen. He graduated from King's College School, London and from King's College Medical School, Edinburgh, but never practiced medicine. Like his brother Roland, he collected all kinds of natural history specimens but later restricted himself to plants. He began medical studied in 1860 and spent some time in 1864 at the University of Edinburgh acting as a clinical assistant to Professor Bennett. He also became a friend of John Hutton Balfour, Professor J.H. Balfour at the Botanical Society of Scotland, Edinburgh Botanical Society.

Sichuan
Sichuan is a province in Southwestern China, occupying the Sichuan Basin and Tibetan Plateau—between the Jinsha River to the west, the Daba Mountains to the north, and the Yunnan–Guizhou Plateau to the south. Its capital city is Chengdu, and its population stands at 83 million. Sichuan neighbors Qinghai and Gansu to the north, Shaanxi and Chongqing to the east, Guizhou and Yunnan to the south, and Tibet to the west. During antiquity, Sichuan was home to the kingdoms of Ba and Shu until their incorporation by the Qin. During the Three Kingdoms era (220–280), Liu Bei's state of Shu was based in Sichuan. The area was devastated in the 17th century by Zhang Xianzhong's rebellion and the area's subsequent Manchu conquest, but recovered to become one of China's most productive areas by the 19th century. During World War II, Chongqing served as the temporary capital of the Republic of China, and was heavily bombed. It was one of the last mainland areas captured ...

Flora Of Bhutan
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. 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 ...

Monotypic Rosaceae Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical system. ...

Flora Of China (series)
''Flora of China'' is a scientific publication aimed at describing the plants native to China. It is the English-language revision of ''Flora Reipublicae Popularis Sinicae'' (FRPS, ). The project is a collaborative scientific effort to publish the first modern English-language account of the 31,000 species of vascular plants of China. This number includes about 8,000 species of medicinal and economically important plants and about 7,500 species of trees and shrubs. ''Flora of China'' describes and otherwise documents these species. The revision in ''Flora of China'' uses taxonomy reflecting the current understanding of each group. The sequence of families is a modified Englerian system, similar to that used in FRPS; however, the circumscription of some families reflects the present understanding of the groups. It is intended that all the vascular plants of China will be covered, including descriptions, identification keys, essential synonymy, phenology, provincial distributio ...

Traditional Medicine
Traditional medicine (also known as indigenous medicine or folk medicine) refers to the knowledge, skills, and practices rooted in the cultural beliefs of various societies, especially Indigenous groups, used for maintaining health and treating illness. In some Asia, Asian and Africa, African countries, up to 80% of people rely on traditional medicine for primary health care. Traditional medicine includes systems like Ayurveda, traditional Chinese medicine, and Unani medicine, Unani. The World Health Organization supports their integration, but warns of potential risks and calls for more research on their safety and effectiveness. The use of medicinal herbs spans over 5,000 years, beginning with ancient civilizations like the Sumer, Sumerians, Ancient Egypt, Egyptians, Indian people, Indians, and Chinese people, Chinese, evolving through Ancient Greece, Greek, Ancient Rome, Roman, Islam, Islamic, and Middle Ages, medieval European traditions, and continuing into Colonial histo ...

Meadow
A meadow ( ) is an open habitat or field, vegetated by grasses, herbs, and other non- woody plants. Trees or shrubs may sparsely populate meadows, as long as they maintain an open character. Meadows can occur naturally under favourable conditions but are often artificially created from cleared shrub or woodland for the production of hay, fodder or livestock. Meadow habitats as a group are characterized as semi-natural grasslands, meaning that they are largely composed of species native to the region, with only limited human intervention. Meadows attract a multitude of wildlife and support flora and fauna that could not thrive in other habitats. They are ecologically important since they provide areas for animal courtship displays, nesting, food gathering, pollinating insects, and sometimes sheltering if the vegetation is high enough. Intensified agricultural practices (too frequent mowing, use of mineral fertilizers, manure and insecticides) may lead to declin ...

Montane
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures lapse rate, fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands and shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the alpine climate, climate becomes co ...

Soil
Soil, also commonly referred to as earth, is a mixture of organic matter, minerals, gases, water, and organisms that together support the life of plants and soil organisms. Some scientific definitions distinguish dirt from ''soil'' by restricting the former term specifically to displaced soil. Soil consists of a solid collection of minerals and organic matter (the soil matrix), as well as a porous phase that holds gases (the soil atmosphere) and water (the soil solution). Accordingly, soil is a three- state system of solids, liquids, and gases. Soil is a product of several factors: the influence of climate, relief (elevation, orientation, and slope of terrain), organisms, and the soil's parent materials (original minerals) interacting over time. It continually undergoes development by way of numerous physical, chemical and biological processes, which include weathering with associated erosion. Given its complexity and strong internal connectedness, soil ecologists ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limestone
Limestone is a type of carbonate rock, carbonate sedimentary rock which is the main source of the material Lime (material), lime. It is composed mostly of the minerals calcite and aragonite, which are different Polymorphism (materials science), crystal forms of calcium carbonate . Limestone forms when these minerals Precipitation (chemistry), precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly Dolomite (rock), dolomite, a closely related rock, which contains a high percentage of the mineral Dolomite (mine ...
