Aloe Perfoliata
''Aloe perfoliata'', the rubble aloe or mitre aloe, is a hardy creeping aloe, found in rocky, mountainous areas throughout the Western Cape, South Africa. Naming and classification ''Aloe perfoliata'' was formerly known as ''Aloe mitriformis''. The physical appearance of this aloe varies greatly depending on environment, and consequently various sub-populations have previously often been mistaken for being separate species. The South African National Biodiversity Institute now recognizes that these are all members of the same species, ''Aloe perfoliata'', comprising what were previously known as ''Aloe mitriformis'', ''Aloe distans'', ''Aloe comptonii'', ''Aloe albispina'' and ''Aloe flavispina'' among others. This species is the most widespread of a group of closely related "Creeping Aloes" ('' Mitriformes''), including the cliff-hanging aloes ''A. meyeri'' and ''A. dabenorisana''(stemless), as well as spotted '' Aloe arenicola'' of the South African west coast and the unusual ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fynbos
Fynbos (; meaning fine plants) is a small belt of natural shrubland or heathland vegetation located in the Western Cape and Eastern Cape provinces of South Africa. This area is predominantly coastal and mountainous, with a Mediterranean climate and rainy winters. The fynbos ecoregion is within the Mediterranean forests, woodlands, and scrub biome. In fields related to biogeography, fynbos is known for its exceptional degree of biodiversity and endemism, consisting of about 80% (8,500 fynbos) species of the Cape floral kingdom, where nearly 6,000 of them are endemic. This land continues to face severe human-caused threats, but due to the many economic uses of the fynbos, conservation efforts are being made to help restore it. Overview and history The word fynbos is often confusingly said to mean "fine bush" in Afrikaans, as "bos" means "bush". Typical fynbos foliage is ericoid rather than fine. The term, in its pre-Afrikaans, Dutch form, ''fynbosch'', was recorded by Nob ... [...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] |
Aloe
''Aloe'' (; also written ''Aloë'') is a genus containing over 650 species of flowering succulent plants.WFO (2022): Aloe L. Published on the Internet;http://www.worldfloraonline.org/taxon/wfo-4000001341. Accessed on: 06 Nov 2022 The most widely known species is '' Aloe vera'', or "true aloe". It is called this because it is cultivated as the standard source for assorted pharmaceutical purposes. Other species, such as ''Aloe ferox'', are also cultivated or harvested from the wild for similar applications. The APG IV system (2016) places the genus in the family Asphodelaceae, subfamily Asphodeloideae. Within the subfamily it may be placed in the tribe Aloeae.Stevens, P.F. (2001 onwards).Asphodelaceae. ''Angiosperm Phylogeny Website''. Retrieved 2016-06-09. In the past, it has been assigned to the family Aloaceae (now included in the Asphodeloidae) or to a broadly circumscribed family Liliaceae (the lily family).

Aloe × Nobilis
''Aloe'' × ''nobilis'' is a commonly cultivated hybrid aloe in the family Asphodelaceae. It is an artificial hybrid, possibly between ''Aloe mitriformis ''Aloe perfoliata'', the rubble aloe or mitre aloe, is a hardy creeping aloe, found in rocky, mountainous areas throughout the Western Cape, South Africa. Naming and classification ''Aloe perfoliata'' was formerly known as ''Aloe mitriformis''. ...'' and '' Aloe brevifolia''. History ''Aloe'' × ''nobilis'' was described in 1812 by Adrian Hardy Haworth. Although both parent species are South African, it likely emerged from crosses between cultivated plants in Europe, as it has not been found in the wild in South Africa. It is one of the most commonly cultivated aloes in Europe, and has become naturalised in parts of Portugal.

Aloe Brevifolia
''Aloe brevifolia'', the short-leaved aloe, is a species of flowering plant in the family Asphodelaceae. It is a tiny, compact, blue-green evergreen succulent perennial, that is native to the Western Cape, South Africa. Listed as Vulnerable on IUCN's global Red List, it is threatened in its natural habitat, but is also widely popular as an ornamental plant in rockeries and desert gardens worldwide. As it requires winter heat, in temperate regions it is grown under glass or as a houseplant. Distribution In the wild, this diminutive species is completely confined to the dry clay soil of “ Rûens Shale Renosterveld” – a critically endangered and rapidly disappearing vegetation type. Small populations are normally found growing on inaccessible rocky slopes and cliffs, especially near the coast, but it is thought that these are merely relics of what was once a much wider distribution. There are several subspecies, which are now separated from each other by farmland and other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cutting (plant)
A plant cutting is a piece of a plant that is used in horticulture for vegetative (asexual) propagation. A piece of the stem or root of the source plant is placed in a suitable medium such as moist soil. If the conditions are suitable, the plant piece will begin to grow as a new plant independent of the parent, a process known as striking. A stem cutting produces new roots, and a root cutting produces new stems. Some plants can be grown from leaf pieces, called leaf cuttings, which produce both stems and roots. The scions used in grafting are also called cuttings. Propagating plants from cuttings is an ancient form of cloning. There are several advantages of cuttings, mainly that the produced offspring are practically clones of their parent plants. If a plant has favorable traits, it can continue to pass down its advantageous genetic information to its offspring. This is especially economically advantageous as it allows commercial growers to clone a certain plant to ensure consis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flower
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae). The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) resulting from cross-pollination or allow selfing (fusion of sperm and egg from the same flower) when self-pollination occurs. There are two types of pollination: self-pollination and cross-pollination. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is when pollen is transferred from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination happens in flowers where the stamen and carpel mature at the same time, and are positi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wall
A wall is a structure and a surface that defines an area; carries a load; provides security, shelter, or soundproofing; or, is decorative. There are many kinds of walls, including: * Walls in buildings that form a fundamental part of the superstructure or separate interior rooms, sometimes for fire safety *Glass walls (a wall in which the primary structure is made of glass; does not include openings within walls that have glass coverings: these are windows) * Border barriers between countries * Brick walls * Defensive walls in fortifications * Permanent, solid fences * Retaining walls, which hold back dirt, stone, water, or noise sound * Stone walls * Walls that protect from oceans (seawalls) or rivers (levees) Etymology The term ''wall'' comes from Latin ''vallum'' meaning "...an earthen wall or rampart set with palisades, a row or line of stakes, a wall, a rampart, fortification..." while the Latin word ''murus'' means a defensive stone wall. English uses the same wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slope
In mathematics, the slope or gradient of a line is a number that describes both the ''direction'' and the ''steepness'' of the line. Slope is often denoted by the letter ''m''; there is no clear answer to the question why the letter ''m'' is used for slope, but its earliest use in English appears in O'Brien (1844) who wrote the equation of a straight line as and it can also be found in Todhunter (1888) who wrote it as "''y'' = ''mx'' + ''c''". Slope is calculated by finding the ratio of the "vertical change" to the "horizontal change" between (any) two distinct points on a line. Sometimes the ratio is expressed as a quotient ("rise over run"), giving the same number for every two distinct points on the same line. A line that is decreasing has a negative "rise". The line may be practical – as set by a road surveyor, or in a diagram that models a road or a roof either as a description or as a plan. The ''steepness'', incline, or grade of a line is measured by the absolute ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cliff
In geography and geology, a cliff is an area of rock which has a general angle defined by the vertical, or nearly vertical. Cliffs are formed by the processes of weathering and erosion, with the effect of gravity. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. Cliffs are usually composed of rock that is resistant to weathering and erosion. The sedimentary rocks that are most likely to form cliffs include sandstone, limestone, chalk, and dolomite. Igneous rocks such as granite and basalt also often form cliffs. An escarpment (or scarp) is a type of cliff formed by the movement of a geologic fault, a landslide, or sometimes by rock slides or falling rocks which change the differential erosion of the rock layers. Most cliffs have some form of scree slope at their base. In arid areas or under high cliffs, they are generally exposed jumbles of fallen rock. In areas of higher moisture, a soil slope may obscure the talus. Many cliffs also fea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
