Haworthia Cooperi
''Haworthia cooperi'' is a diverse and varied species of the genus ''Haworthia'' in the family Asphodelaceae, endemic to the Eastern Cape Province in South Africa. Description Plants grow in clumps of small rosettes of tiny, fleshy, light green leaves. As one of the soft green group of ''Haworthias'' it is frequently confused with its relatives (e.g. ''Haworthia cymbiformis'', ''Haworthia mucronata'' and '' Haworthia marumiana''). A distinctive feature is the slight bristley "awn" on the margins of the leaves of most varieties. In some, the leaves terminate in a long bristle or thread. Its leaves are not recurved like the "retuse" Haworthias (e.g. ''Haworthia mirabilis'' or ''Haworthia retusa''). Another feature is that the leaves have transparent streaks around their tips. With some varieties, the entire leaf tip is transparent. In the wild, the sun is very bright, and the plant grows mostly buried by sand with only these transparent tips above the ground.

John Gilbert Baker
John Gilbert Baker (13 January 1834 – 16 August 1920) was an English botanist. His son was the botanist Edmund Gilbert Baker (1864–1949). Biography Baker was born in Guisborough in North Yorkshire, the son of John and Mary (née Gilbert) Baker, and died in Kew. He was educated at Quaker schools at Ackworth School and Bootham School, York. He then worked at the library and herbarium of the Royal Botanic Gardens, Kew between 1866 and 1899, and was keeper of the herbarium from 1890 to 1899. He wrote handbooks on many plant groups, including Amaryllidaceae, Bromeliaceae, Iridaceae, Liliaceae, and ferns. His published works includ''Flora of Mauritius and the Seychelles''(1877) and ''Handbook of the Irideae'' (1892). He married Hannah Unthank in 1860. Their son Edmund was one of twins, and his twin brother died before 1887. John G. Baker was elected a Fellow of the Royal Society in 1878. He was awarded the Veitch Memorial Medal of the Royal Horticultural Society in 1907. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haworthia Mucronata
''Haworthia mucronata'' is a species of the genus ''Haworthia'' in the family Asphodelaceae, endemic to the Little Karoo region, in the Western Cape Province of South Africa. Etymology The genus name ''Haworthia'' honors the British botanist Adrian Hardy Haworth (1767–1833), while the species epitheton ''mucronata'' ("pointy") derives from Latin and refers to the pointed leaf-shape. Description Plants grow as tight proliferous clumps of offsetting rosettes. As one of the soft-leaved, pale-green group of ''Haworthias'' it is frequently confused with its relatives (e.g. ''Haworthia cooperi'', ''Haworthia cymbiformis'' and '' Haworthia marumiana''). It also hybridises naturally with ''Haworthia arachnoidea'' in habitat, and the two seem to form a continuum. The distinctive feature of this species is the transparency of the keel and margins of the leaves. This distinguishes it from most of its relatives. Some plants have bristles along their leaf margins but this is not a dist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Flora Of South Africa
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Port Elizabeth
Gqeberha (), formerly Port Elizabeth and colloquially often referred to as P.E., is a major seaport and the most populous city in the Eastern Cape province of South Africa. It is the seat of the Nelson Mandela Bay Metropolitan Municipality, South Africa's second-largest metropolitan district by area size. It is the sixth-most populous city in South Africa and is the cultural, economic and financial centre of the Eastern Cape. The city was founded as Port Elizabeth in 1820 by Sir Rufane Donkin, who was the governor of the Cape at the time. He named it after his late wife, Elizabeth, who had died in India. The Donkin memorial in the CBD of the city bears testament to this. Port Elizabeth was established by the government of the Cape Colony when 4,000 British colonists settled in Algoa Bay to strengthen the border region between the Cape Colony and the Xhosa. It is nicknamed "The Friendly City" or "The Windy City". In 2019, the Eastern Cape Geographical Names Committee recommended ...

Haworthia Retusa
''Haworthia retusa'' is a species of flowering plants of the genus ''Haworthia'' in the family Asphodelaceae, endemic to a very small area around Riversdale, in the Western Cape Province in South Africa. Growing to tall and broad, it is a perennial succulent with thick triangular leaves and small white tubular flowers held in tall racemes. Etymology The genus name ''Haworthia'' honors the British botanist Adrian Hardy Haworth (1767–1833), while the species epitheton ''retusa'' derives from Latin and refers to the "retused" leaf-shape. Description A distinctive feature is the " retuse", deltoid, recurved shape of the leaves. The upturned, recurved face of each leaf forms a triangle, which is transparent (and often lined). The species can be easily recognised by its leaf-top windows, which are distinctively shiny. Plants grow as tight rosettes of thick, firm, fleshy, highly recurved/truncated leaves. It is usually a solitary rosette in the wild. In cultivation it can off ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haworthia Mirabilis
''Haworthia mirabilis'' is a species of the genus ''Haworthia'' belonging to the family Asphodelaceae. Etymology The genus name ''Haworthia'' honors the British botanist Adrian Hardy Haworth (1767–1833), while the species epitheton ''mirabilis'' derives from Latin and means "wonderful”. Description ''Haworthia mirabilias'' is a succulent evergreen slow-growing species reaching a size of in height. It is usually a solitary stemless plant. The leaves are green, with longitudinal pale green lines along the upper surfaces and small teeth along the margins. They turn to brownish or reddish in the sun. The leaves form a rosette and the flowers are white and small, in an inflorescence. This highly variable species is one of the ''"retuse"'' species of ''Haworthia'', meaning that it usually grows sunken beneath the ground with its flattened leaves only showing on the surface. Its rosette of succulent leaves are turned back ("retuse") so as to provide a flat and level face on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haworthia Marumiana
''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] |
Haworthia Cymbiformis
''Haworthia cymbiformis'' is a species of the genus ''Haworthia'' in the family Asphodelaceae, endemic to the Eastern Cape Province in South Africa. Description Plants are small and grow clumps of rosettes of thick, fleshy, light green leaves. As one of the soft green group of ''Haworthias'' it is frequently confused with its relatives (e.g. '' Haworthia cooperi'' which shares a similar distribution range, as well as ''Haworthia mucronata'' and '' Haworthia marumiana'' to the west). A distinctive feature is the soft, "boat-shaped" leaves (''"cymbiformis"'' actually means "boat-shaped"). Its leaves are not recurved like the "retuse" Haworthias (e.g. ''Haworthia mirabilis'' or ''Haworthia retusa''). Another feature is that the leaves usually have transparent streaks around their tips. In the wild, the sun is very bright, and the plant grows mostly buried by sand with only these transparent tips above the ground. Distribution and habitat The natural range of this species is rou ...

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] |
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. Their structure is an example of a modified stem in which the 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 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 families have varieties with rosette 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 plant. Function in flowering plants Often, rosettes form in perennial plants whose upper foliage dies back with the remaining vegetation protecting the plant. Ano ...
