Leucadendron Pondoense
''Leucadendron pondoense'', the Pondoland conebush, is a flower-bearing shrub that belongs to the genus ''Leucadendron'' and forms part of the fynbos. The plant is native to the Eastern Cape where it occurs in the Pondoland from Port St. Johns to Port Edward. Description The shrub grows tall and flowers from September to December. The plant dies after a fire but the seeds survive. The seeds are stored in a toll on the female plant and fall to the ground after a fire, possibly spreading by the wind. The plant is unisexual Dioecy (; ; adj. dioecious , ) is a characteristic of a species, meaning that it has distinct individual organisms (unisexual) that produce male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproductio ... and there are separate plants with male and female flowers, which are pollinated by the wind. Distribution and habitat The plant grows in river beds. The tree's national number is 81.4. In Afrikaans, it is know ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abraham Erasmus Van Wyk
Abraham Erasmus van Wyk, also known as Braam van Wyk (born 1952, Wolmaransstad) is a South African plant taxonomist. He has been responsible for the training of a significant percentage of the active plant taxonomists in South Africa and has also produced the first electronic application (app) for the identification of trees in southern Africa. Education and career Van Wyk was born in 1952 in Wolmaransstad, North-West Province, South Africa and grew up on a maize (corn) and cattle farm. In 1973, he completed a BSc (Botany, Zoology, Physiology) at Potchefstroom University for Christian Higher Education (PCHO), followed by a BSc (Hons) in 1974, a Higher Diploma in Education in 1976 and a MSc (Botany) in 1977 (supervised by DJ Botha). All of the degrees he completed at PCHO with obtained with distinction. He then went on to the University of Pretoria where he obtained his PhD in botany with a thesis on the classification of the genus Eugenia (''Myrtaceae'') in southern Africa. ...

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] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Leucadendron
''Leucadendron'' is a genus of about 80 species of flowering plants in the family Proteaceae, endemic to South Africa, where they are a prominent part of the fynbos ecoregion and vegetation type. Description Species in the genus ''Leucadendron'' are small trees or shrubs that are erect or creeping. Most species are shrubs that grow up to 1 m tall, some to 2 or 3 m. A few grow into moderate-sized trees up to 16 m tall. All are evergreen. The leaves are largely elliptical, sometimes needle-like, spirally arranged, simple, entire, and usually green, often covered with a waxy bloom, and in the case of the Silvertree, with a distinct silvery tone produced by dense, straight, silky hairs. This inspired the generic name ''Leucadendron'', which literally means "white tree". The flowers are produced in dense inflorescences at the branch tips; plants are dioecious, with separate male and female plants. The seed heads, or infructescences, of ''Leucadendron'' are woody cone-like structures ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastern Cape
The Eastern Cape is one of the provinces of South Africa. Its capital is Bhisho, but its two largest cities are East London and Gqeberha. The second largest province in the country (at 168,966 km2) after Northern Cape, it was formed in 1994 out of the Xhosa homelands or bantustans of Transkei and Ciskei, together with the eastern portion of the Cape Province. The central and eastern part of the province is the traditional home of the indigenous Xhosa people. In 1820 this area which was known as the Xhosa Kingdom began to be settled by Europeans who originally came from England and some from Scotland and Ireland. Since South Africa's early years, many Xhosas believed in Africanism and figures such as Walter Rubusana believed that the rights of Xhosa people and Africans in general, could not be protected unless Africans mobilized and worked together. As a result, the Eastern Cape is home to many anti-apartheid leaders such as Robert Sobukwe, Oliver Tambo, Nelson Mandel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EmaMpondweni
Pondoland or Mpondoland (Xhosa language, Xhosa: ''EmaMpondweni''), is a natural region on the South African shores of the Indian Ocean. It is located in the coastal belt of the Eastern Cape province. Its territory is the former Mpondo Kingdom of the Mpondo people. Geography Mpondoland stretches between the Mthatha River, whose river mouth, mouth is its southernmost point, and the Mtamvuna River in the north along a coastal strip that is not more than 50 km wide. The Mzimvubu River divides Mpondoland into an eastern and a western region. It is a mountainous area whose main vegetation consists in thornveld, grassland, as well as subtropical evergreen forests in the humid Coast, coastal valleys. History The Khoikhoi and San people had inhabited the region since ancient times in scattered nomadic groups. About 500 AD the Xhosa speaking Ngunis settled in the area, for the mountain grasslands were a good resource for cattle-rearing. Geographically Mpondoland was a remote area, n ...

Port St
A port is a maritime facility comprising one or more wharves or loading areas, where ships load and discharge cargo and passengers. Although usually situated on a sea coast or estuary, ports can also be found far inland, such as Hamburg, Manchester and Duluth; these access the sea via rivers or canals. Because of their roles as ports of entry for immigrants as well as soldiers in wartime, many port cities have experienced dramatic multi-ethnic and multicultural changes throughout their histories. Ports are extremely important to the global economy; 70% of global merchandise trade by value passes through a port. For this reason, ports are also often densely populated settlements that provide the labor for processing and handling goods and related services for the ports. Today by far the greatest growth in port development is in Asia, the continent with some of the world's largest and busiest ports, such as Singapore and the Chinese ports of Shanghai and Ningbo-Zhou ...

Port Edward, KwaZulu-Natal
Port Edward is a small resort town situated on the south coast of KwaZulu-Natal in South Africa. It lies north of the Mtamvuna Gorge which includes the Mtamvuna River and is the border between KwaZulu-Natal and the Eastern Cape. It is situated on the R61 road (future N2 Wild Coast Toll Route) between Port Shepstone and Lusikisiki. History In 1831 there was a crisis between the settlers in Port Natal (Durban) and Dingane, the Zulu king. Some settlers boarded a ship that was in the harbour and the others, including Henry Francis Fynn and his family, fled down the coast. The Zulu warriors caught up with them where Port Edward is today and massacred the fleeing settlers, which included local tribespeople of Langeni, on a hill called Isandlundlu (in English, ''shaped like a hut''). The place has been known ever since as Tragedy Hill and its slopes are still littered with the bones of the victims. In 1552, the Portuguese carrick "Sao Joao" ran aground at Port Edward and this is th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Reproductive Morphology
Plant reproductive morphology is the study of the physical form and structure (the morphology) of those parts of plants directly or indirectly concerned with sexual reproduction. Among all living organisms, flowers, which are the reproductive structures of angiosperms, are the most varied physically and show a correspondingly great diversity in methods of reproduction. Plants that are not flowering plants (green algae, mosses, liverworts, hornworts, ferns and gymnosperms such as conifers) also have complex interplays between morphological adaptation and environmental factors in their sexual reproduction. The breeding system, or how the sperm from one plant fertilizes the ovum of another, depends on the reproductive morphology, and is the single most important determinant of the genetic structure of nonclonal plant populations. Christian Konrad Sprengel (1793) studied the reproduction of flowering plants and for the first time it was understood that the pollination process involved ...
