Aloe Albida
''Aloe albida'' is a dwarf species of succulent plant. Characteristics Its flowers are small, white and borne on a single inflorescence. Its flowering time is usually in early autumn (March–April in the Southern Hemisphere), although it may begin to flower as early as February. The leaves form a rosette and have a waxy coating, which gives them a pale greyish/bluish green colour. Habitat It grows in montane grassland and in crevices among rocks where grasses are kept fairly short. It is found on the mountains in Barberton in Mpumalanga Province of South Africa to the northern border, of as well as parts of Eswatini (Swaziland). See also *''Aloe'' *Asphodelaceae *Succulent plants In botany, succulent plants, also known as succulents, are plants with parts that are thickened, fleshy, and engorged, usually to retain water in arid climates or soil conditions.

Otto Stapf (botanist)
Otto Stapf FRS (23 April 1857 – 3 August 1933) was an Austrian born botanist and taxonomist, the son of Joseph Stapf, who worked in the Hallstatt salt-mines. He grew up in Hallstatt and later published about the archaeological plant remains from the Late Bronze- and Iron Age mines that had been uncovered by his father. Stapf studied botany in Vienna under Julius Wiesner, where he received his PhD with a dissertation on cristals and cristalloids in plants. 1882 he became assistant professor (''Assistent'') of Anton Kerner. In 1887 he was made ''Privatdozent'' (lecturer without a chair) in Vienna. He published the results of an expedition Jakob Eduard Polak, the personal physician of Nasr al-Din, the Shah of Persia, had conducted in 1882, and plants collected by Felix von Luschan in Lycia and Mesopotamia 1881–1883. In 1885, Polak sponsored Stapf to conduct a botanical expedition of his own to South- and Western Persia, which was to last nine month. This led to the disco ...

Montane Grassland
Montane grasslands and shrublands are a biome defined by the World Wildlife Fund. The biome includes high elevation grasslands and shrublands around the world. The term "montane" in the name of the biome refers to "high elevation", rather than the ecological term that denotes the region below the treeline. This biome includes high elevation (montane and alpine) grasslands and shrublands, including the puna and páramo in South America, subalpine heath in New Guinea and East Africa, steppes of the Tibetan plateaus, as well as other similar subalpine habitats around the world. The plants and animals of tropical montane páramos display striking adaptations to cool, wet conditions and intense sunlight. Around the world, characteristic plants of these habitats display features such as rosette structures, waxy surfaces, and abundant pilosity. The páramos of the northern Andes are the most extensive examples of this habitat type. Although ecoregion biotas are most diverse in the ...

Plants Described In 1933
Plants are the eukaryotes that form the kingdom Plantae; they are predominantly photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts, mosses, lycophytes, ferns, conifers and other gymnosperm ...

Succulent Plants
In botany, succulent plants, also known as succulents, are plants with parts that are thickened, fleshy, and engorged, usually to retain water in arid climates or soil conditions. The word ''succulent'' comes from the Latin word ''sucus'', meaning "juice" or "sap". Succulents may store water in various structures, such as leaves and stems. The water content of some succulent organs can get up to 90–95%, such as '' Glottiphyllum semicyllindricum'' and ''Mesembryanthemum barkleyii''. Some definitions also include roots, thus geophytes that survive unfavorable periods by dying back to underground storage organs (caudex) may be regarded as succulents. The habitats of these water-preserving plants are often in areas with high temperatures and low rainfall, such as deserts, but succulents may be found even in alpine ecosystems growing in rocky or sandy soil. Succulents are characterized by their ability to thrive on limited water sources, such as mist and dew, which makes them equi ...

Asphodelaceae
Asphodelaceae is a family of flowering plants in the order Asparagales. Such a family has been recognized by most taxonomists, but the circumscription has varied widely. In its current circumscription in the APG IV system, it includes about 40 genera and 900 known species. The type genus is '' Asphodelus''. The family has a wide, but scattered, distribution throughout the tropics and temperate zones; for example, ''Xanthorrhoea'' is endemic to Australia, while the '' Aloes'' are unique to Africa and parts of the Arabian Peninsula. Many of the family's genera are cultivated as ornamentals, with some being highly collectible and sought-after, such as ''Haworthia'' and '' Gasteria'', as well as their intergeneric hybrids with ''Aloe'' ('' x Gasteraloe'', x ''Gastorthia'', x ''Haworthaloe'', etc.), while a few are grown commercially for cut flowers. Two species of ''Aloe'', '' A. vera'' and '' A. maculata'', are grown for their leaf sap, which contains digestive enzymes, an ...

Eswatini
Eswatini, formally the Kingdom of Eswatini, also known by its former official names Swaziland and the Kingdom of Swaziland, is a landlocked country in Southern Africa. It is bordered by South Africa on all sides except the northeast, where it shares a border with Mozambique. At no more than north to south and east to west, Eswatini is one of the smallest countries in Africa; despite this, its climate and topography are diverse, ranging from a cool and mountainous highveld to a hot and dry lowveld. The population is composed primarily of Swazi people, ethnic Swazis. The prevalent language is Swazi language, Swazi (''siSwati'' in native form). The Swazis established their kingdom in the mid-18th century under the leadership of Ngwane III. The country and the Swazi take their names from Mswati II, the 19th-century king under whose rule the country was expanded and unified; its boundaries were drawn up in 1881 in the midst of the Scramble for Africa. After the Second Boer War, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mpumalanga
Mpumalanga () is one of the nine provinces of South Africa. The name means "East", or literally "The Place Where the Sun Rises" in the Nguni languages. Mpumalanga lies in eastern South Africa, bordering Eswatini and Mozambique. It shares borders with the South African provinces of Limpopo to the north, Gauteng to the west, the Free State (province), Free State to the southwest, and KwaZulu-Natal to the south. The capital is Mbombela. Mpumalanga was formed in 1994, when the area that was the Eastern Transvaal (province), Transvaal was merged with the former bantustans KaNgwane, KwaNdebele and parts of Lebowa and Gazankulu. Although the contemporary borders of the province were formed only at the end of apartheid, the region and its surroundings have a history that extends back thousands of years. Much of its history and current significance are as a region of trade. History Precolonial Era Archeological sites in the Mpumalanga region indicate settlement by humans and ...

Barberton, Mpumalanga
Barberton is a town in the Mpumalanga province of South Africa, which has its origin in the 1880s gold rush in the region. It is situated in the De Kaap Valley and is fringed by the Makhonjwa Mountains. It is south of Mbombela and east of Johannesburg. Barberton was the seat of the Umjindi Local Municipality until the day of the 2016 Municipal Elections, when the Umjindi Local Municipality was merged into the Mbombela Local Municipality. History Prehistoric The mountains around Barberton are amongst the oldest in the world, dating back 3.5 billion years, and these mountains include some of the oldest exposed rocks on the planet. These volcanic rocks, which scientists call the Barberton Greenstone Belt, have given direct evidence of the conditions of life on the surface of the very early Earth. In the satellite image, the bare rocks of mountain peaks appear as a pale grey-green, accentuated by the sharp relief of sunlit slopes and their shadows. Deeper shades of gree ...

Grass
Poaceae ( ), also called Gramineae ( ), is a large and nearly ubiquitous family (biology), family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos, the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest :plant families, plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, including staple foods from domesticated cereal crops such as maize, wheat, rice, oats, barley, and millet for people and as forage, feed for livestock, meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rosette (botany)
In botany, a rosette is a circular arrangement of leaves or of structures resembling leaves. In flowering plants, rosettes usually sit near the soil, but they can also be at the top of an otherwise naked branch or trunk. Their structure is an example of a Aerial stem modification, modified stem in which the internode (botany), internode gaps between the leaves do not expand, so that all the leaves remain clustered tightly together and at a similar height. Some insects induce the development of Gall, galls that are leafy rosettes. In bryophytes and algae, a rosette results from the repeated branching of the thallus as the plant grows, resulting in a circular outline. Taxonomies Many plant family (taxonomy), families have varieties with rosette Morphology (biology), morphology; they are particularly common in Asteraceae (such as dandelions), Brassicaceae (such as cabbage), and Bromeliaceae. The fern ''Blechnum fluviatile'' or New Zealand Water Fern (''kiwikiwi'') is a rosette plan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gilbert Westacott Reynolds
Gilbert Westacott Reynolds (10 October 1895 Bendigo – 7 April 1967 Mbabane) was a South African optometrist and authority on the genus ''Aloe''. Gilbert Reynolds arrived in Johannesburg with his parents in 1902, where his father started business as an optician. He received his education at St John's College where he was Victor Ludorum. After the outbreak of World War I, he enlisted and saw active service in South West Africa and Nyasaland with the rank of captain. Having qualified as optometrist he joined his father's practice in 1921. Reynolds developed a keen interest in the bulbs and succulents of South Africa at about this time. When he started his own country practice about 1930, he was able to travel extensively and gradually narrowed his interests to ''Aloe''. Reynolds was guided in the early stages of his research by Dr I. C. Verdoorn and Dr R. A. Dyer of the Botanical Research Institute in Pretoria, later becoming the authority on ''Aloe'' and having an extensive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
