Haworthia Fasciata
''Haworthiopsis fasciata'', formerly ''Haworthia fasciata'', is a species of succulent plant from the Eastern Cape Province, South Africa. The species is rare in cultivation; most plants that are labelled as ''H. fasciata'' are actually ''Haworthiopsis attenuata''. Description The plants are generally small, less than 10 cm (4 in) high. The triangular shaped leaves are green with narrow white crested strips on the outside. At the end of the leaf is a non acute spine. The summer flowers appear in October and November, on the end of an inflorescence. The species has similar markings to ''Haworthiopsis attenuata'', which is commonly grown as a house plant. The two are therefore frequently confused with each other, and a great many ''H. attenuata'' specimens are mislabelled as the rarer ''H. fasciata''. However ''Haworthiopsis fasciata'' is rare in cultivation, and can easily be distinguished by the smooth upper (ie. inner) surfaces of its leaves. Its whit ...

Carl Ludwig Von Willdenow
Carl Ludwig Willdenow (22 August 1765 – 10 July 1812) was a German botanist, pharmacist, and plant taxonomist. He is considered one of the founders of phytogeography, the study of the geographic distribution of plants. Willdenow was also a mentor of Alexander von Humboldt, one of the earliest and best known phytogeographers. He also influenced Christian Konrad Sprengel, who pioneered the study of plant pollination and floral biology. Biography Willdenow was born in Berlin and studied medicine and botany at the University of Halle. After studying pharmaceutics at Wieglieb College, Langensalza and in medicine at Halle, he returned to Berlin to work at his father's pharmacy located in the Unter den Linden. His early interest in botany was kindled by his uncle J. G. Gleditsch and he started a herbarium collection in his teenage years. In 1794 he became a member of the Berlin Academy of Sciences. He was a director of the Botanical garden of Berlin from 1801 until his death. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haworthiopsis Reinwardtii
''Haworthiopsis reinwardtii'', formerly ''Haworthia reinwardtii'', is a species of succulent flowering plant in the family Asphodelaceae, native to the Eastern Cape Province of South Africa. It is one of the species of ''Haworthiopsis'' that is commonly cultivated as an ornamental. Description It is a perennial succulent, with stems growing to in height, with a basal rosette of white-spotted fleshy leaves arranged in a spiral pattern, and racemes of tubular pinkish-white flowers in spring. The plant spreads to form a mat, by means of freely-produced offsets, also a convenient means of propagation. It is frequently confused with ''Haworthiopsis coarctata'' - a closely related species which occurs just to the west of this species' natural range and looks very similar. However ''H. reinwardtii'' has larger, flatter and whiter tubercles on its leaves (those of ''H. coarctata'' are smaller, smoother and rounder). ''H. reinwardtii'' also has thinner, narrower leaves.

Flora Of The Cape Provinces
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] |

World Checklist Of Selected Plant Families
The World Checklist of Selected Plant Families (usually abbreviated to WCSP) is an "international collaborative programme that provides the latest peer reviewed and published opinions on the accepted scientific names and synonyms of selected plant families." Maintained by the Royal Botanic Gardens, Kew, it is available online, allowing searches for the names of families, genera and species, as well as the ability to create checklists. The project traces its history to work done in the 1990s by Kew researcher Rafaël Govaerts on a checklist of the genus ''Quercus''. Influenced by the Global Strategy for Plant Conservation, the project expanded. , 173 families of seed plants were included. Coverage of monocotyledon families is complete; other families are being added. There is a complementary project called the International Plant Names Index (IPNI), in which Kew is also involved. The IPNI aims to provide details of publication and does not aim to determine which are accepted spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uitenhage
Uitenhage ( ; ), officially renamed Kariega, is a South African town in the Eastern Cape Province. It is well known for the Volkswagen factory located there, which is the biggest car factory on the African continent. Along with the city of Port Elizabeth and the small town of Despatch, it forms the Nelson Mandela Metropolitan Municipality. History Uitenhage was founded on 25 April 1804 by ''landdrost'' (district magistrate) Jacob Glen Cuyler and named in honour of the Cape's Commissioner-General Jacob Abraham Uitenhage de Mist by the Dutch Cape Colony governor, Jan Willem Janssens. Uitenhage formed part of the district of Graaff Reinet (shortly after its short-lived secession). The Cape Colony received a degree of independence when "Responsible Government" was declared in 1872. In 1875, the Cape government of John Molteno took over the rudimentary Uitenhage railway site, incorporated it into the Cape Government Railways (CGR), and began construction of the lines connecting Uit ...

Fynbos
Fynbos (; meaning fine plants) is a small belt of natural shrubland or heathland vegetation located in the Western Cape and Eastern Cape provinces of South Africa. This area is predominantly coastal and mountainous, with a Mediterranean climate and rainy winters. The fynbos ecoregion is within the Mediterranean forests, woodlands, and scrub biome. In fields related to biogeography, fynbos is known for its exceptional degree of biodiversity and endemism, consisting of about 80% (8,500 fynbos) species of the Cape floral kingdom, where nearly 6,000 of them are endemic. This land continues to face severe human-caused threats, but due to the many economic uses of the fynbos, conservation efforts are being made to help restore it. Overview and history The word fynbos is often confusingly said to mean "fine bush" in Afrikaans, as "bos" means "bush". Typical fynbos foliage is ericoid rather than fine. The term, in its pre-Afrikaans, Dutch form, ''fynbosch'', was recorded by Nob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haworthia Longiana
''Haworthia'' is a large genus of small succulent plants endemic to Southern Africa (Mozambique, Namibia, Lesotho, Eswatini and South Africa). Like the aloes, they are members of the subfamily Asphodeloideae and they generally resemble miniature aloes, except in their flowers, which are distinctive in appearance. They are popular garden and container plants. Description and characteristics ''Haworthias'' are small succulent plants, forming rosettes of leaves from to exceptionally in diameter, depending on the species. These rosettes are usually stemless but in some species stems reach up to . The inflorescences of some species may exceed in height. The plants can grow solitary or can be clump-forming. Many species have firm, tough, fleshy leaves, usually dark green in colour, whereas others are softer and contain leaf windows with translucent panels through which sunlight can reach internal photosynthetic tissues. Their flowers are small, and generally white. Though they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haworthiopsis Coarctata
''Haworthiopsis coarctata'', formerly ''Haworthia coarctata'', is a species of flowering succulent plant from the Eastern Cape Province, South Africa and naturalized in Mexico. It is one of the species of ''Haworthiopsis'' that is commonly cultivated as an ornamental. Description ''H. coarctata'' grows in large clumps in its natural habitat, with long stems packed with robust succulent leaves. It is normally dark green but sometimes acquires a rich purple-red when in full sunlight. It is frequently confused with ''Haworthiopsis reinwardtii'', which occurs just to the east of its natural range. However ''H. coarctata'' has smaller, smoother and rounder tubercles on its leaves (those of ''H.reinwardtii'' are sometimes larger, flatter and whiter). ''H. coarctata'' also usually has much wider, fatter leaves. Forms and varieties This is a variable species, and several forms and varieties are recognised. Several are listed below: * ''H. coarctata'' var. ''adelaidensis' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haworthiopsis Glauca
''Haworthiopsis glauca'', formerly ''Haworthia glauca'', is a species of flowering succulent plant from the Eastern Cape Province, South Africa. Description ''H. glauca'' typically has pointed, light blue succulent leaves (''"glauca"'' = "blue"), which are packed densely along its stems. The stems branch from the base, and the plant can form clumps. The leaves of this variable species are sometimes incurved, sometimes vertical and erect, and sometimes spreading. In some varieties, the leaves have slight tubercles. Among the more common varieties are var. ''herrei'' (with tubercles) and the gracile var. ''jonesiae'' (with pencil-thin stems). Taxonomy The species was previously included in ''Haworthia'' subgenus ''Hexangulares''. Phylogenetic studies demonstrated that subgenus ''Hexangulares'' was actually relatively unrelated to other haworthias and so it was moved to the new genus ''Haworthiopsis''. Distribution This species extends across the western part of the Eastern Cape ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Green
Green is the color between cyan and yellow on the visible spectrum. It is evoked by light which has a dominant wavelength of roughly 495570 Nanometre, nm. In subtractive color systems, used in painting and color printing, it is created by a combination of yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesis, photosynthesize and convert sunlight into chemical energy. Many creatures have adapted to their green environments by taking on a green hue themselves as camouflage. Several minerals have a green color, including the emerald, which is colored green by its chromium content. During Post-classical history, post-classical and Early modern period, early modern Europe, green was the color commonly assoc ...
