Tulista Kingiana
''Tulista kingiana'' is a species of succulent plant, from the Western Cape, South Africa. It is listed as Endangered on the IUCN global Red List It was formerly classed in the genus ''Haworthia'', as ''Haworthia kingiana''. Description and taxonomy It is an evergreen succulent plant with rosettes of short, sharp, bright green, succulent leaves. The leaves are usually covered with flat, shiny tubercles. These are usually rounded and white, but they are occasionally elongated or slightly translucent. The plant gradually produces offsets and can form clumps. In November and December it produces pink-white flowers. The bright, yellow-green colour is the distinguishing feature of ''Tulista kingiana''. In other ways though, this species is quite variable. Even in one locality there can be great variety in leaf shape, growth form and tubercles. It was formerly classed in the genus ''Haworthia'', with the other large species ('' T.pumila'', '' T.minima'' & '' T.marginata'') in the ...

Mossel Bay
Mossel Bay ( af, Mosselbaai) is a harbour town of about 99,000 people on the Southern Cape (or Garden Route) of South Africa. It is an important tourism and farming region of the Western Cape Province. Mossel Bay lies 400 kilometres east of the country's seat of parliament, Cape Town (which is also the capital city of the Western Cape), and 400 km west of Port Elizabeth, the largest city in the Eastern Cape. The older parts of the town occupy the north-facing side of the Cape St Blaize Peninsula, whilst the newer suburbs straddle the Peninsula and have spread eastwards along the sandy shore of the Bay. The town's economy relied heavily on farming, fishing and its commercial harbour (the smallest in the Transnet Port Authority's stable of South African commercial harbours), until the 1969 discovery of natural offshore gas fields led to the development of the gas-to-liquids refinery operated by PetroSA. Tourism is another driver of Mossel Bay's economy. Etymology The origi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haworthia Minima
''Tulista minima'' is a species of succulent plant, from the far south of the Western Cape, South Africa. It was formerly classed in the genus ''Haworthia'', as ''Haworthia minima''. However this was not the correct name, as the name ''Haworthia minor'' in fact had priority. When the species was transferred to the new genus ''Tulista'', a combination was first published for ''Tulista minima'', which was likewise invalid. A new combination was therefore needed for ''Tulista minor'', which was accordingly published in 2018. Description It is a small evergreen succulent plant, with hard, fleshy blue-green leaves that are covered in white tubercles. It offsets readily and can form clumps. It produces white flowers with pink tips in the summer (November to December). It is a variable species, with different populations differing in the leaf shape, colour, growth form and tubercles. Popular varieties include ''T. minima'' var. ''poellnitziana'', as well as the ''opalina'' and ... [...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] |
Renosterveld
Renosterveld is a term used for one of the major plant communities and vegetation types of the Cape Floristic Region (Cape Floral Kingdom) which is located in southwestern and southeastern South Africa, in southernmost Africa. It is an ecoregion of the Mediterranean forests, woodlands, and scrub biome. Etymology Renosterveld directly translated in the Afrikaans language means "rhinoceros-field", a possible reference to the high number of rhinoceroses seen by the Afrikaner settlers at the time. It may also derive its name from the renosterbos ("rhinoceros bush - ''Elytropappus rhinocerotis''), which is a common species of shrub found here. The dull grey colour of renosterbos is similar to the colour of a rhino's hide. Geology Renosterveld plants grow on rich soil, which makes them more nutritious than typical fynbos plants. Typically, renosterveld is largely confined to fine-grained soils - mainly clays and silts - which are derived from the shales of the Malmesbury and Bokkeve ...

Little Karoo
The Karoo ( ; from the Afrikaans borrowing of the South Khoekhoe !Orakobab or Khoemana word ''ǃ’Aukarob'' "Hardveld") is a semi-desert natural region of South Africa. No exact definition of what constitutes the Karoo is available, so its extent is also not precisely defined. The Karoo is partly defined by its topography, geology and climate, and above all, its low rainfall, arid air, cloudless skies, and extremes of heat and cold.Potgieter, D.J. & du Plessis, T.C. (1972) ''Standard Encyclopaedia of Southern Africa''. Vol. 6. pp. 306–307. Nasou, Cape Town.''Reader’s Digest Illustrated Guide to Southern Africa''. (5th Ed. 1993). pp. 78–89. Reader’s Digest Association of South Africa Pty. Ltd., Cape Town. The Karoo also hosted a well-preserved ecosystem hundreds of million years ago which is now represented by many fossils. The ǃ’Aukarob formed an almost impenetrable barrier to the interior from Cape Town, and the early adventurers, explorers, hunters, and travelers o ...

Tulista
''Tulista'' is a small genus of succulent plants endemic to South Africa. They were formerly included within the genus ''Haworthia''. Characteristics The genus is characterised by a large size (relative to other haworthias), by their stemless rosette growth form, by the yellow exudate in their non-fibrous leaves, and by their distinctive flowers with robust peduncles. Taxonomy The genus ''Haworthia'' was long considered problematic, and suspected of being polyphyletic. It was accordingly divided into three different subgenera: ''Haworthia'' (the soft, green, leafy, and often retuse species); ''Hexangulares'' (the harder, often tubercled species); ''Robustipedunculares'' (the four largest, most robust species). Several phylogenetic studies have confirmed this division, and shown that ''Haworthia'' actually comprises three clades that are only distantly related. Based on phylogenetic evidence, in 2013, Gordon Rowley revived the genus ''Tulista'', first erected by Constantine Sam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phylogenetic
In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, protein amino acid sequences, or morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An unrooted tree diagram (a network) makes no assumption about the ancestral line, and does ...

Haworthia Marginata
''Tulista marginata'' is a species of ''Tulista'' succulent plant, from the Western Cape, South Africa. Description and taxonomy It is an evergreen, winter-growing succulent plant with short, sharp leaves arranged in rosettes of 20 cm in diameter. The leaves are hard, keeled, upright, pale in colour, and can be with tubercles. In the summer (November to December), T.marginata produces pink-white flowers on a multi-branched inflorescence. ''Tulista marginata'' is a variable species, with different populations and varieties, differing in the leaf shape, colour, growth form and tubercles. It was formerly classed in the genus ''Haworthia'', within which it was one of the largest species. It was classed with the other large species ('' T.pumila'', '' T.minima'' and '' T.kingiana'') in the ''"Robustipedunculares"'' subgenus. Following recent phylogenetic studies, it has been shown that these four species in fact constitute a distinct out-group, separate from other Haworthias. ...

Tulista Pumila
''Tulista pumila'' ("Vratjiesaalwee") is a species of ''Tulista'' succulent plant, from the Western Cape, South Africa. It was formerly placed in the genus ''Haworthia'', as ''Haworthia pumila'' or ''Haworthia maxima''. Description It is an evergreen, winter-growing succulent plant with sharp succulent leaves arranged in rosettes of 20 cm in diameter. The leaves are hard, upright, sometimes incurved and are usually covered with raised white tubercles. It is a variable species, with different populations differing in the leaf shape, colour, growth form and tubercles. It also varies according to environment, and in direct sun during the dry summer, it can assume a red colour. The leaves usually have an olive-green to brown colour. In the summer (November to December) ''Tulista pumila'' produces pink-white tubular flowers, on a tall thin inflorescence. Naming and taxonomy The eponymy of this species has been relatively complex. It was previously named ''Haworthia maxima'' or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Plant Names Index
The International Plant Names Index (IPNI) describes itself as "a database of the names and associated basic bibliographical details of seed plants, ferns and lycophytes." Coverage of plant names is best at the rank of species and genus. It includes basic bibliographical details associated with the names. Its goals include eliminating the need for repeated reference to primary sources for basic bibliographic information about plant names. The IPNI also maintains a list of standardized author abbreviations. These were initially based on Brummitt & Powell (1992), but new names and abbreviations are continually added. Description IPNI is the product of a collaboration between The Royal Botanic Gardens, Kew (Index Kewensis), The Harvard University Herbaria (Gray Herbarium Index), and the Australian National Herbarium ( APNI). The IPNI database is a collection of the names registered by the three cooperating institutions and they work towards standardizing the information. The stan ...

Haworthia
''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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
