Protea Witzenbergiana
''Protea witzenbergiana'', or Swan sugarbush, is a flowering shrub of the genus '' Protea''. Taxonomy ''Protea witzenbergiana'' was first described by Edwin Percy Phillips in 1910, from specimens found growing in the Witzenberg range by Karl Ludwig Philipp Zeyher and William John Burchell. Description The shrub spreads out and can become three metres in diameter and half a metre high. It blooms in Autumn to early Winter, from March to June with the peak in April to May. Distribution The plant is endemic to the Western Cape, South Africa, and occurs from the Cederberg, through the Koue Bokkeveld Mountains and the Witzenberg, to Hex River Mountains and the Bokkerivier Mountains. It is found near the towns of Tulbagh and Ceres. It is somewhat similar to '' Protea pityphylla'' and ''P. pendula''. Ecology Potential wildfires destroy the shrub, but the seeds can survive such an event. The plant is monoecious with both sexes in each flower. It is thought that rodents are pro ...

South African National Biodiversity Institute
The South African National Biodiversity Institute (SANBI) is an organisation established in 2004 in terms of the National Environmental Management: Biodiversity Act, No 10 of 2004, under the South African Department of Environmental Affairs (later named Department of Environment, Forestry and Fisheries), tasked with research and dissemination of information on biodiversity, and legally mandated to contribute to the management of the country’s biodiversity resources. History SANBI was established on 1 September 2004 in terms of the National Environmental Management: Biodiversity Act, No 10 of 2004. Previously, in 1989, the autonomous statutory National Botanical Institute (NBI) had been formed from the National Botanic Gardens and the Botanical Research Institute, which had been founded in the early 20th century to study and conserve the South African flora. The mandate of the National Botanical Institute was expanded by the act to include the full diversity of the South Af ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cederberg
The Cederberg mountains are located near Clanwilliam, approximately 300 km north of Cape Town, South Africa at about . The mountain range is named after the endangered Clanwilliam cedar (''Widdringtonia wallichii''), which is a tree endemic to the area. The mountains are noted for dramatic rock formations and San rock art. The Cederberg Wilderness Area is administered by CapeNature. ''Cederberg'' is now the generally accepted spelling for the area, which combines the English (Cedarberg) and Afrikaans (Sederberg) variants. Geography and climate The Cederberg mountains extend about 50 km north–south by 20 km east–west. They are bordered on the west by the Sandveld, the north by the Pakhuis Mountains, the east by the Springbok Flats and the south by the Kouebokkeveld Mountains and the Skurweberge. The main access road, the N7, runs to the west of the range. The nearest towns are Citrusdal to the southwest and Clanwilliam to the north. The area is spars ...

Monoecious
Monoecy (; adj. monoecious ) is a sexual system in seed plants where separate male and female cones or flowers are present on the same plant. It is a monomorphic sexual system alongside gynomonoecy, andromonoecy and trimonoecy. Monoecy is connected to anemophily. It can prevent self-pollination in an individual flower but cannot prevent self-pollination between male and female flowers on the same plant. Monoecy in angiosperms has been of interest for evolutionary biologists since Charles Darwin. Terminology Monoecious comes from the Greek words for one house. History The term monoecy was first introduced in 1735 by Carl Linnaeus. Darwin noted that the flowers of monoecious species sometimes showed traces of the opposite sex function. Monoecious hemp was first reported in 1929. Occurrence Monoecy is most common in temperate climates and is often associated with inefficient pollinators or wind-pollinated plants. It may be beneficial to reducing pollen-stigma interferenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wildfire
A wildfire, forest fire, bushfire, wildland fire or rural fire is an unplanned, uncontrolled and unpredictable fire in an area of Combustibility and flammability, combustible vegetation. Depending on the type of vegetation present, a wildfire may be more specifically identified as a bushfire(bushfires in Australia, in Australia), desert fire, grass fire, hill fire, peat fire, prairie fire, vegetation fire, or veld fire. Fire ecology, Some natural forest ecosystems depend on wildfire. Wildfires are distinct from beneficial human usage of wildland fire, called controlled burn, controlled burning, although controlled burns can turn into wildfires. Fossil charcoal indicates that wildfires began soon after the appearance of terrestrial plants approximately 419 million years ago during the Silurian period. Earth's carbon-rich vegetation, seasonally dry climates, atmospheric oxygen, and widespread lightning and volcanic ignitions create favorable conditions for fires. The occurre ...

Protea Pendula
''Protea pendula'', also known as the nodding sugarbush or arid sugarbush, is a flowering plant of the genus ''Protea'', in the family Proteaceae, which is only found growing in the wild in the Cape Region of South Africa. In the Afrikaans language it is known as ''knikkopsuikerbossie'' or ''ondersteboknopprotea''. Taxonomy ''Protea pendula'' was first described by Robert Brown in his 1810 treatise ''On the Proteaceae of Jussieu''. The holotype is an ''exsiccata'' collection made by Francis Masson in the early 1770s in an unspecified location in South Africa. There is an isotype in the herbarium assembled by William Forsyth, which is now held at Kew. The species was collected again in 1831 by Karl Ludwig Philipp Zeyher (accompanied by Christian Friedrich Ecklon) in the Witzenberg Mountains to the east of the town of Tulbagh. Description This plant grows as an erect shrub up to three metres tall. The younger branches are softly hirsute, eventually becoming glabrous with ...

Protea Pityphylla
''Protea pityphylla'', also known as Ceres sugarbush or mountain rose (along with a number of similar species), is a flowering shrub of the genus '' Protea'', in the family Proteaceae. The plant is endemic to the southwestern Cape Region of South Africa. Names In the Afrikaans language the vernacular names ''hekskaamblom'' and less specifically ''skaamblom'' have been recorded for this plant, ''skaamblom'' being a name it shares with other similar proteas. The name ''skaamblom'' translates as 'shy' or 'bashful' flower, and possibly refers to the nodding, downward-pointing inflorescences. It was first attested in the 1929 article titled ''Gewone Plantname in die Distrik Riversdal'' by Muir in ''Die Huisgenoot'' for the species ''Protea nana''. Taxonomy ''Protea pityphylla'' was first described by Edwin Percy Phillips in 1910. It was collected 27 years earlier, in 1883, by the British botanist A. A. Bodkin (collection #6089) at an elevation of 549 metres on the Michell's Pass t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceres, Western Cape
Ceres is the administrative centre and largest town of the Witzenberg Local Municipality in the Western Cape Province of South Africa. Ceres serves as a regional centre for the surrounding towns of Wolseley, Tulbagh, Op-die-Berg and Prince Alfred Hamlet. It is situated in the ''Warmbokkeveld'' (Afrikaans: "warm antelope field") Valley about 170 km north-east of Cape Town. Ceres is located at the north-eastern entrance to Michell's Pass and was the old route north between Cape Town and Johannesburg, which was later replaced by the N1 highway, which traverses the Breede River Valley to the south. Named after the Roman goddess of agriculture, Ceres, a name which is fitting as the valley in which the town is situated is extremely fertile and is a major producer of South Africa's deciduous fruit. Geography and climate Ceres experiences a typical Mediterranean climate tempered by its altitude. The town experiences warmer temperatures in summer, due to its inland location with ...

Tulbagh
Tulbagh, named after Dutch Cape Colony Governor Ryk Tulbagh, is a town located in the "Land van Waveren" mountain basin (also known as the Tulbagh basin), in the Winelands of the Western Cape, South Africa. The basin is fringed on three sides by mountains, and is drained by the Klein Berg River and its tributaries. The nearest towns are Ons Rust and Gouda beyond the Nuwekloof Pass, Wolseley some to the south inside the basin, and Ceres and Prince Alfred Hamlet beyond Michell's Pass in the Warm Bokkeveld. History The basin has been inhabited for thousands of years by indigenous Bushmen and Khoi-San peoples. It was about 300 years ago when, after a land grant by the Dutch Colonial Government to a more or less equal number of Dutch and Huguenot settlers to settle the area, that the town of Tulbagh was founded. The region was named "Land van Waveren" in 1699 by Willem Adriaan van der Stel in honour of the Oetgens van Waveren family, from which his mother was descended. Before ...

Hex River Mountains
The Hex River Mountains ( af, Hexrivierberge) make up the second highest mountain range in the Western Cape province of South Africa and are located 120 kilometres (75 miles) north-east of Cape Town. They form part of a large anticline in the Cape Fold Belt mountain system and form a north-east, south-west trending mountain system forming the core of the Cape Syntaxis between the towns of Worcester and De Doorns. They are mostly composed of Table Mountain sandstone and most peaks reach 2,000 metres (6,562 feet) in height or more. The highest mountain is Matroosberg at 2,249 metres (7,379 feet), making it the second tallest peak in the province after Seweweekspoort Peak in the Swartberg Mountain Range. The vegetation is primarily montane fynbos and the mountains fall within the Cape's Mediterranean climate. The mountains provide some rudimentary snow-skiing opportunities in winter, with the Western Cape's heaviest snowfalls occurring in and around these ranges. The surrounding va ...

Koue Bokkeveld Mountains
The Koue Bokkeveld, meaning "Cold Buck Shrubland" in Afrikaans, is a mountain range in the Western Cape Province, South Africa. Geologically the range is composed of Cedarberg Sandstone of the Cape System. Location and extent It is located above Prince Alfred Hamlet, north of Ceres, and south and east of Citrusdal. The range runs in a WNW-ESE direction with a tall escarpment on its southern and southwestern side. Elevations of the range are an average of 1,600 m and there is often snow in winter. These heights are one of the coldest places in the Western Cape in winter. Drainage The Koue Bokkeveld falls within the Olifants/Doring system and the Doring River has its sources in this range, contributing substantially to the flow of the Olifants catchment area. Ecology The flora of the Koue Bokkeveld is similar to the Cedarberg flora, with mountain fynbos at high altitudes, Karoo vegetation on the lower slopes and patches of Mountain cypress.

Shrub
A shrub (often also called a bush) is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some definitions state that a shrub is less than and a tree is over 6 m. Others use as the cut-off point for classification. Many species of tree may not reach this mature height because of hostile less than ideal growing conditions, and resemble a shrub-sized plant. However, such species have the potential to grow taller under the ideal growing conditions for that plant. In terms of longevity, most shrubs fit in a class between perennials and trees; some may only last about five y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
