Grewia Mollis
''Grewia mollis'' is a widespread species of flowering plant in the family Malvaceae, native to tropical Africa, Yemen and Oman. It is the source of grewia gum, an edible polysaccharide mucilage, similar in its properties to tragacanth gum. It can be affected by a smut fungi, called '' Pericladium grewiae'' , which was found on a plant in Eritrea. References mollis Mollis is a former municipality in the canton of Glarus in Switzerland.

Antoine Laurent De Jussieu
Antoine Laurent de Jussieu (; 12 April 1748 – 17 September 1836) was a French botanist, notable as the first to publish a natural classification of flowering plants; much of his system remains in use today. His classification was based on an extended unpublished work by his uncle, the botanist Bernard de Jussieu. Life Jussieu was born in Lyon, France, in 1748, as one of 10 children, to Christophle de Jussieu, an amateur botanist. His father's three younger brothers were also botanists. He went to Paris in 1765 to be with his uncle Bernard and to study medicine, graduating with a doctorate in 1770, with a thesis on animal and vegetable physiology. His uncle introduced him to the Jardin du Roi, where he was appointed as a botany Demonstrator and deputy to L. G. Le Monnier, professor of botany there in 1770. Le Monnier had succeeded Antoine-Laurent's uncle Antoine in 1759. Lectures by eminent botanists, including the Jusssieu dynasty were popular there, especially among pha ...

Flora Of West Tropical Africa
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Yemen
The wildlife of Yemen is substantial and varied. Yemen is a large country in the southern half of the Arabian Peninsula with several geographic regions, each with a diversity of plants and animals adapted to their own particular habitats. As well as high mountains and deserts, there is a coastal plain and long coastline. The country has links with Europe and Asia, and the continent of Africa is close at hand. The flora and fauna have influences from all these regions and the country also serves as a staging post for migratory birds. Geography Yemen is in the southern half of the Arabian Peninsula, bordering the Red Sea, the Gulf of Aden and the Arabian Sea. The country is divided into four geographical regions: the Tihamah or coastal plains to the west, the western highlands, the central highlands, and the Rub' al Khali, or "Empty Quarter", in the east, the largest sand desert in the world. The Tihamah forms an arid flat plain alongside the Red Sea coast. There are many lagoons h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Zambia
The wildlife of Zambia refers to the natural flora and fauna of Zambia. This article provides an overview, and outline of the main wildlife areas or regions, and compact lists of animals focusing on prevalence and distribution in the country rather than on taxonomy. More specialized articles on particular groups are linked from here. Overview Ecoregions Using the World Wildlife Fund's classification of ecoregions, Zambia may include miombo, mopane and Baikiaea woodland savanna, with grasslands (mainly flooded grasslands) and evergreen forest also present. The chief determinant of the distribution of ecoregions and wildlife is climate. See ''Climate of Zambia'' for more detail. Animals outside the national parks Zambia's "big game" wildlife (including sports fishing) is the foundation of its tourism industry now. One of its biggest employers and foreign-exchange earners: Victoria Falls and cultural events come second and third in importance. However for domestic tourism, this or ...

Flora Of Angola
The wildlife of Angola is composed of its flora and fauna. An atlas of the amphibians and reptiles of Angola was published in 2018, and reported 117 species of amphibians and 278 of reptiles. A major book on the biodiversity of Angola was published in 2019, and reported more than 2,000 species of organisms (plants, invertebrates and vertebrate animals), and 1,313 fossil species. Fauna Mammals Birds The avifauna of Angola includes a total of 983 species, of which 14 are endemic, 1 has been introduced by humans, and 4 are rare or accidental. 20 species are globally threatened. The western Angola Endemic Bird Area has 14 range-restricted species. Little is known about the conservation status of the region's birds due to the civil war that has raged in Angola for the last 27 years. The greatest diversity of restricted-range species is found in Cuanza Sul province, and given the uncertainty about their current status, many of these species are listed as Threatened. Gabela B ...

Grewia
''Grewia'' is a large flowering plant genus in the mallow family Malvaceae, in the expanded sense as proposed by the Angiosperm Phylogeny Group. Formerly, Grewia was placed in either the family Tiliaceae or the Sparrmanniaceae. However, these were both not monophyletic with respect to other Malvales - as already indicated by the uncertainties surrounding placement of ''Grewia'' and similar genera - and have thus been merged into the Malvaceae. Together with the bulk of the former Sparrmanniaceae, ''Grewia'' is in the subfamily Grewioideae and therein the tribe Grewieae, of which it is the type genus. The genus was named by Carl Linnaeus, in honor of the botanist Nehemiah Grew (1641-1712) from England. Grew was one of the leading plant anatomists and microscope researchers of his time, and his study of pollen laid the groundwork for modern-day palynology. Ecology and uses Several Lepidoptera caterpillars are found to feed on ''Grewia'' species. These include the common nawab ( ...

Malvaceae
Malvaceae, or the mallows, is a family of flowering plants estimated to contain 244 genera with 4225 known species. Well-known members of economic importance include okra, cotton, cacao and durian. There are also some genera containing familiar ornamentals, such as ''Alcea'' (hollyhock), ''Malva'' (mallow), and ''Tilia'' (lime or linden tree). The largest genera in terms of number of species include ''Hibiscus'' (300 species), ''Sterculia'' (250 species), ''Dombeya'' (250 species), '' Pavonia'' (200 species) and '' Sida'' (200 species). Taxonomy and nomenclature The circumscription of the Malvaceae is controversial. The traditional Malvaceae '' sensu stricto'' comprise a very homogeneous and cladistically monophyletic group. Another major circumscription, Malvaceae ''sensu lato'', has been more recently defined on the basis that genetics studies have shown the commonly recognised families Bombacaceae, Tiliaceae, and Sterculiaceae, which have always been considered closely allie ...

Smut Fungi
The smuts are multicellular fungi characterized by their large numbers of teliospores. The smuts get their name from a Germanic word for dirt because of their dark, thick-walled, and dust-like teliospores. They are mostly Ustilaginomycetes (phylum Basidiomycota) and can cause plant disease. The smuts are grouped with the other basidiomycetes because of their commonalities concerning sexual reproduction. Smuts are cereal and crop pathogens that most notably affect members of the grass family (Poaceae) and sedges (Cyperaceae). Economically important hosts include maize, barley, wheat, oats, sugarcane, and forage grasses. They eventually hijack the plants' reproductive systems, forming galls which darken and burst, releasing fungal teliospores which infect other plants nearby. Before infection can occur, the smuts need to undergo a successful mating to form dikaryotic hyphae (two haploid cells fuse to form a dikaryon). Wild rice smut ''Ustilago esculenta'' is a species of fungus i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
