Duvalia Elegans
''Duvalia elegans'' (the "elegant Duvalia") is a small succulent plant species, in the family Apocynaceae. It is the type species of the genus ''Duvalia'', and it is endemic to the Western Cape Province, South Africa. Description This species closely resembles the widespread and common '' Duvalia caespitosa'', and the two species often grow alongside each other within the Breede River Valley. However, the flowers of ''Duvalia elegans'' are smaller (15-22mm diameter) and distinctive. Their five radiating corolla-tips are very dark brown-purple, glossy and usually densely hairy. The shape of the corolla-tips is slightly triangular, because their margins are spread out, and only slightly reflexed (not tightly folded down, replicate, like those of most ''Duvalia'' species). The centre of the flower is covered by a prominent, flat coronal disc, which is not glossy, and is often a lighter colour. The flowers are usually held out on long stalks that grow from the base of each ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ...

Breede River Valley
Breede River Valley is a region of Western Cape Province, South Africa known for being the largest fruit and wine producing valley in the Western Cape, as well as South Africa's leading race-horse breeding area. It is part of the Cape Winelands, Boland bordering on becoming Little Karoo towards the east. Geography The Breede River Valley is relatively broad and flat for a Western Cape valley, averaging at a floor height of 80m-250m above sea-level. Western regions are mostly alluvial and flat, while eastern regions have more hills of the Bokkeveld Group with narrow alluvial deposits. The valley is framed by the high mountains of the Cape Fold Belt, with the Hex River Mountains and the Skurweberge to the northwest, the Langeberg Mountains (up to 2000m) to the north, the smaller Boland Mountains to the southwest, and the Riviersonderend Mountains to the south. It stretches from Tulbagh in the north to McGregor, Western Cape, McGregor in the south and Rawsonville in the west to Ash ...

Shale
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.Blatt, Harvey and Robert J. Tracy (1996) ''Petrology: Igneous, Sedimentary and Metamorphic'', 2nd ed., Freeman, pp. 281–292 Shale is characterized by its tendency to split into thin layers ( laminae) less than one centimeter in thickness. This property is called '' fissility''. Shale is the most common sedimentary rock. The term ''shale'' is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the more narrow sense of clay-rich fissile mudrock. Texture Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable beddin ...

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 ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Euphorbia Tridentata
''Euphorbia tridentata'' is a species of succulent Euphorbia, spurge native to the southern Cape, South Africa. Description A small, low, spreading, semi-geophytic stem-succulent, with tuberous roots and rhizomes. During the dry seasons, the stems can die back above ground. The stems are somewhat segmented. Each branch is rounded-to-cylindrical, but at its point of growth it is constricted. The solitary cyathia are carried on short Peduncle (botany), peduncles. Their five involucral glands each carry 3 or 4 distinctive finger-like outgrowths. Distribution and habitat ''Euphorbia tridentata'' is Endemism, endemic to South Africa. In the Western Cape Province, it occurs around the town of Riversdale, westwards to Heidelberg and eastwards to Mossel Bay and Hartenbos.

Overberg
__NOTOC__ Overberg is a region in South Africa to the east of Cape Town beyond the Hottentots-Holland mountains. It lies along the Western Cape Province's south coast between the Cape Peninsula and the region known as the Garden Route in the east. The boundaries of the Overberg are the Hottentots-Holland mountains in the West; the Riviersonderend Mountains, part of the Cape Fold Belt, in the North; the Atlantic and Indian Oceans in the South and the Breede River in the East. The area has always been considered as the breadbasket of the Cape and is largely given to grain farming — mainly wheat. The wheat fields are a major breeding ground for South Africa's national bird, the blue crane. Another important crop in the Overberg is fruit, with the Elgin Valley producing about 60 percent of the total annual apple crop of about 819 000 tonnes (2012 data). Nestled in the Overberg, one can find the Kogelberg Biosphere Reserve (recognised and registered with UNESCO) populated wi ...

Swellendam
Swellendam is the fifth oldest town in South Africa (after Cape Town, Stellenbosch, Simon's Town, and Paarl), a town with 17,537 inhabitants situated in the Western Cape province. The town has over 50 provincial heritage sites, most of them buildings of Cape Dutch architecture. Swellendam is situated on the N2, approximately 220 km from both Cape Town and George. History Early travellers and explorers who visited the Cape in the 16th century traded with the Khoikhoi people who lived on these shores and in the interior. When the Dutch East India Company established a replenishment station at the Cape in 1652, trade continued inland as far as Swellendam. In 1743 Swellendam was declared a magisterial district, the third-oldest in South Africa, and was named after Governor Hendrik Swellengrebel, the first South African born Governor, and his wife, Helena Ten Damme. This outlying settlement soon became a gateway to the interior, and was visited by many famous explorers an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Duvalia Vestita
''Duvalia vestita'' is a small succulent plant species, in the family Apocynaceae, indigenous to the southernmost part of the Western Cape Province, South Africa. Description ''Duvalia vestita'' is sometimes considered to be a subspecies of ''D.caespitosa''. The flowers are 20-30mm in diameter, and are brownish-red to almost black. The central annulus is covered in short, dark hairs. The Petal, lobes are also hairy, at least near their bases where they are also slightly more spread out than typical ''Duvalia caespitosa''. The margins of the lobes are not ciliate. The stems are variable, but are sometimes slender and rhizomatous, like those of ''Duvalia immaculata''. Individual stems are 5-22mm wide and 10-80mm long. The tiny (maximum 1mm) leaf-rudiments barely have stipular glands. When not in flower, ''D.vestita'' can resemble ''Orbea variegata'', a species it often grows among. Like ''D.caespitosa'', ''D.vestita'' is a tetraploid. In appearance, it is somewhat intermediate b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apocynaceae
Apocynaceae (from ''Apocynum'', Greek for "dog-away") is a family of flowering plants that includes trees, shrubs, herbs, stem succulents, and vines, commonly known as the dogbane family, because some taxa were used as dog poison Members of the family are native to the European, Asian, African, Australian, and American tropics or subtropics, with some temperate members. The former family Asclepiadaceae (now known as Asclepiadoideae) is considered a subfamily of Apocynaceae and contains 348 genera. A list of Apocynaceae genera may be found here. Many species are tall trees found in tropical forests, but some grow in tropical dry (xeric) environments. Also perennial herbs from temperate zones occur. Many of these plants have milky latex, and many species are poisonous if ingested, the family being rich in genera containing alkaloids and cardiac glycosides, those containing the latter often finding use as arrow poisons. Some genera of Apocynaceae, such as '' Adenium'', bleed clea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petal
Petals are modified Leaf, leaves that surround the reproductive parts of flowers. They are often advertising coloration, brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include Genus, genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as ''Rose, Rosa'' and ''Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Sinc ...
