Tulista 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
''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] |
Western Cape
The Western Cape is a province of South Africa, situated on the south-western coast of the country. It is the fourth largest of the nine provinces with an area of , and the third most populous, with an estimated 7 million inhabitants in 2020. About two-thirds of these inhabitants live in the metropolitan area of Cape Town, which is also the provincial capital. The Western Cape was created in 1994 from part of the former Cape Province. The two largest cities are Cape Town and George. Geography The Western Cape Province is roughly L-shaped, extending north and east from the Cape of Good Hope, in the southwestern corner of South Africa. It stretches about northwards along the Atlantic coast and about eastwards along the South African south coast (Southern Indian Ocean). It is bordered on the north by the Northern Cape and on the east by the Eastern Cape. The total land area of the province is , about 10.6% of the country's total. It is roughly the size of England or the S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Haworthia Marginata - Tulista Heidelberg RSA 1
''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 the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
Tulista 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'' an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 ...

Overgrazing
Overgrazing occurs when plants are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods. It can be caused by either livestock in poorly managed agricultural applications, game reserves, or nature reserves. It can also be caused by immobile, travel restricted populations of native or non-native wild animals. Overgrazing reduces the usefulness, productivity, and biodiversity of the land and is one cause of desertification and erosion. Overgrazing is also seen as a cause of the spread of invasive species of non-native plants and of weeds. Degrading land, emissions from animal agriculture and reducing the biomass in a ecosystem contribute directly to climate change. Overgrazing can be reversed or prevented by removing grazers in order to give plants time to recover between grazing events. Successful planned grazing strategies have been support in the American bison of the Great Plains, or migratory Wildebeests of the African savann ...

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 ...

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] |
