Steven Molteno
Stephen or Steven is an English given name, first name. It is particularly significant to Christianity, Christians, as it belonged to Saint Stephen ( ), an early disciple and deacon who, according to the Book of Acts, was stoned to death; he is widely regarded as the first martyr (or "protomartyr") of the Christian Church. The name, in both the forms Stephen and Steven, is often shortened to Steve or Stevie (given name), Stevie. In English, the female version of the name is Stephanie. Many surnames are derived from the first name, including Template:Stephen-surname, Stephens, Stevens, Stephenson, and Stevenson, all of which mean "Stephen's (son)". In modern times the name has sometimes been given with intentionally non-standard spelling, such as Stevan or Stevon. A common variant of the name used in English is Stephan (given name), Stephan ( ); related names that have found some currency or significance in English include Stefan (given name), Stefan (pronounced or in English) ...

Flora Of Southern Africa
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. 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) wa ...

Monotypic Asphodelaceae Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical system. ...

Astroloba Corrugata
''Astroloba corrugata'' is a small succulent plant of the ''Astroloba'' genus, endemic to the Little Karoo and the far south of the Western Cape, South Africa. Naming This plant has been known by several names in its history. It was named "''Astroloba rugosa''" (Roberts Reinecke), "''Astroloba aspera''", and "''Astroloba muricata''", before it gained its current name. Description ''Astroloba corrugata'' is a compact ''Astroloba'' species, with slender, sprawling stems (up to 20 cm long), densely covered in spirally arranged pointed leaves. The leaves point outwards, and have slight non-marginated keels. They are green, but become reddish if exposed to direct sun. The outer side of the leaves are covered with distinctive tiny speckled "asperous" tubercles which (unlike '' Astroloba bullulata'') are the same colour as the leaf. These tubercles sometimes tend to cluster in longitudinal lines. These smaller, more evenly distributed tubercles (sometimes in longitudinal rows ...

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 ...

Western Cape Province
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 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 t ...

Little Karoo
The Karoo ( ; from the Afrikaans borrowing of the South Khoekhoe Khoemana (also known as !Orakobab or Korana) word is a semidesert 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. The Karoo also hosted a well-preserved ecosystem hundreds of millions of years ago which is now represented by many fossils. The Karoo formed an almost impenetrable barrier to the interior from Cape Town, and the early adventurers, explorers, hunters, and travelers on the way to the Highveld unanimously denounced it as a frightening place of great heat, great frosts, great floods, and great droughts. Today, it is still a place of great heat and frosts, and an annual rainfall of between 50 and 250 mm, though on some of the mountains it can be 250 to ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridization, which include genetic and morph ...
