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 on ...

Succulent Plant
In botany, succulent plants, also known as succulents, are plants with parts that are thickened, fleshy, and engorged, usually to retain water in arid climates or soil conditions. The word ''succulent'' comes from the Latin word ''sucus'', meaning "juice" or "sap". Succulent plants may store water in various structures, such as leaf, leaves and Plant stem, stems. The water content of some succulent organs can get up to 90–95%, such as ''Glottiphyllum semicyllindricum'' and ''Mesembryanthemum barkleyii''. Some definitions also include roots, thus geophytes that survive unfavorable periods by dying back to underground storage organs may be regarded as succulents. The habitats of these water-preserving plants are often in areas with high temperatures and low rainfall, such as deserts, but succulents may be found even in Alpine climate, alpine ecosystems growing in rocky soil. Succulents are characterized by their ability to thrive on limited water sources, such as mist and dew, ... [...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] |
Ladismith
Ladismith is a town and agricultural centre in the western Little Karoo region of South Africa's Western Cape province.

Touws River (town)
Touws River ( af, Touwsrivier) is a small railway town of 6,800 people in the Western Cape province of South Africa. It is located on the river of the same name, about north-east of Cape Town. The Touwsrivier CPV Solar Project is located just outside of the town and supplies 50 MW to the national electrical grid. History The town of Touws River owes its existence to the Cape Government Railways, and to the route that their founder, Cape Prime Minister John Molteno, chose for a railway line over the Hex River Mountains. A railway was needed from the port at Cape Town, to service the newly discovered diamond fields in Kimberley. However, several seemingly impregnable ranges of mountains separated Cape Town from the hinterland of the Cape. The Royal Commonwealth Society (1898) records how the route was chosen: ''When Mr. Molteno formulated his railway scheme he sent for his consulting engineer, who asked him what was the route he desired. Mr. Molteno asked for a map of South Afri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barrydale
Barrydale is a village located on the border of the Overberg and Klein Karoo regions of the Western Cape Province in South Africa. It was named after Joseph Barry, a well known merchant of the 19th century. It is situated at the northern end of the Tradouw's pass which winds its way through the mountains to Swellendam. History Barrydale's history dates back to the early 18th century when farmers moved into the area looking for fertile arable land with water. The community built their church on a spot where the R62 and R324 roads meet. In the days before the church was built there were a number of ''nagmaal'' houses (houses where Holy Communion could be celebrated) and a school, but not much else. The Dutch Reformed Community of Barrydale came into being in 1878 when land was purchased to build the church. As the farmers in the area were encouraged to plant vineyards and orchards, it was natural that a winery and distillery would eventually be built. In 1940 the Barrydale Koöpera ...

Astroloba Spirella
''Astroloba spirella'' (="''Astroloba smutsiana''" nom. nud.) is a small succulent plant of the genus ''Astroloba'', restricted to an area of the western section of the Little Karoo, South Africa. Description In appearance it is superficially very similar to ''Astroloba spiralis'', with its sharp, spirally-arranged leaves. However the perianth of ''spiralis'' is both inflated and strongly transversely rugose. ''A. spirella'' is also a smaller plant and has leaves that are sometimes striped with longitudinal streaks near the tips. It can be distinguished from its northern relative, '' Astroloba pentagona'', by its sharply pointed leaves, with properly marginate apices and absence of tubercles or striation. The leaves get a reddish-brown colour in the sun. The flowers appear from January to April, at the end of the dry summer. Distribution It occurs in rocky ridges of shale in the Little Karoo - between Montagu in the west, Barrydale, and Ladismith in the east (where it gradu ...

× Astrolista Bicarinata
The multiplication sign, also known as the times sign or the dimension sign, is the symbol , used in mathematics to denote the multiplication operation and its resulting product. While similar to a lowercase X (), the form is properly a four-fold rotationally symmetric saltire. History The earliest known use of the symbol to represent multiplication appears in an anonymous appendix to the 1618 edition of John Napier's . This appendix has been attributed to William Oughtred, who used the same symbol in his 1631 algebra text, , stating:"Multiplication of species .e. unknownsconnects both proposed magnitudes with the symbol 'in' or : or ordinarily without the symbol if the magnitudes be denoted with one letter." Two earlier uses of a notation have been identified, but do not stand critical examination. Uses In mathematics, the symbol × has a number of uses, including * Multiplication of two numbers, where it is read as "times" or "multiplied by" * Cross product of two vect ...

Nothogenus
In botanical nomenclature, a Hybrid (biology), hybrid may be given a hybrid name, which is a special kind of botanical name, but there is no requirement that a hybrid name should be created for plants that are believed to be of hybrid origin. The ''International Code of Nomenclature for algae, fungi, and plants'' (ICNafp) provides the following options in dealing with a hybrid: * A hybrid may get a name; this will usually be the option of choice for naturally occurring hybrids. * A hybrid may also be indicated by a formula listing the parents. Such a formula uses the multiplication sign "×" to link the parents. ** "It is usually preferable to place the names or epithets in a formula in alphabetical order. The direction of a cross may be indicated by including the sexual symbols (♀: female; ♂: male) in the formula, or by placing the female parent first. If a non-alphabetical sequence is used, its basis should be clearly indicated." (H.2A.1) * Grex (horticulture), Grex names can b ...

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...
