Encephalartos Lanatus
''Encephalartos lanatus'' ( Olifants River cycad) is a species of cycad, a plant belonging to the family Zamiaceae growing in Mpumalanga, South Africa. Its specific epithet, ''lanatus'', means wooly in Latin. Description It is an arborescending portable plant with a 1-1.5 m high stem with a diameter of 25–35 cm which sometimes has suffers or branching off the base. The leaves are 100 cm long and bluish green, almost silvery. They are covered with a thick coat, from which the specific name of this plant is derived. The yellowish spine is straight, with the upper part clearly curved. The leaflets, 10–14 cm long, are arranged on the spine in the opposite way, with an almost horizontal insertion angle; the margins are full and smooth. Basal leaflets are smaller, and often reduced to thorns. It is a goddess species with male-shaped ovoids of red colour, 25–30 cm long and 5–6 cm wide. Female cones, of the same shape, are 25–30 cm long and have a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olifants River (Limpopo)
The Olifants River, Lepelle, iBhalule or Obalule ( af, Olifantsrivier; pt, Rio dos Elefantes) is a river in South Africa and Mozambique, a tributary of the Limpopo River. It falls into the Drainage Area B of the Drainage basins of South Africa. The historical area of the Pedi people, Sekhukhuneland, is located between the Olifants River and one of its largest tributaries, the Steelpoort River. Course The Olifants River has its origin between Breyten and Bethal, Mpumalanga Province. It flows north towards Limpopo Province through Witbank Dam and then the Loskop Dam and is forced east by the Transvaal Drakensberg, cutting through at the Abel Erasmus Pass and then flowing east further across the Lowveld to join with the Letaba River. It crosses into Gaza Province, Mozambique, after cutting through the Lebombo Mountains by way of the Olifants Gorge, becoming the ''Rio dos Elefantes'', and finally joining the Limpopo River after 40 km before it enters the Indian Ocean at Xa ...

Cycad
Cycads are seed plants that typically have a stout and woody (ligneous) trunk (botany), trunk with a crown (botany), crown of large, hard, stiff, evergreen and (usually) pinnate leaves. The species are dioecious, that is, individual plants of a species are either male or female. Cycads vary in size from having trunks only a few centimeters to several meters tall. They typically grow very slowly and live very long. Because of their superficial resemblance, they are sometimes mistaken for Arecaceae, palms or ferns, but they are not closely related to either group. Cycads are gymnosperms (naked-seeded), meaning their fertilization, unfertilized seeds are open to the air to be directly fertilized by pollination, as contrasted with angiosperms, which have enclosed seeds with more complex fertilization arrangements. Cycads have very specialized pollinators, usually a specific species of beetle. Both male and female cycads bear cones (strobilus, strobili), somewhat similar to conife ...

Zamiaceae
The Zamiaceae are a family of cycads that are superficially palm or fern-like. They are divided into two subfamilies with eight genera and about 150 species in the tropical and subtropical regions of Africa, Australia and North and South America. The Zamiaceae, sometimes known as zamiads, are perennial, evergreen, and dioecious. They have subterranean to tall and erect, usually unbranched, cylindrical stems, and stems clad with persistent leaf bases (in Australian genera). Their leaves are simply pinnate, spirally arranged, and interspersed with cataphylls. The leaflets are sometimes dichotomously divided. The leaflets occur with several sub-parallel, dichotomously branching longitudinal veins; they lack a mid rib. Stomata occur either on both surfaces or undersurface only. Their roots have small secondary roots. The coralloid roots develop at the base of the stem at or below the soil surface. Male and female sporophylls are spirally aggregated into determinate cones that gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mpumalanga
Mpumalanga () is a province of South Africa. The name means "East", or literally "The Place Where the Sun Rises" in the Swazi, Xhosa, Ndebele and Zulu languages. Mpumalanga lies in eastern South Africa, bordering Eswatini and Mozambique. It constitutes 6.5% of South Africa's land area. It shares borders with the South African provinces of Limpopo to the north, Gauteng to the west, the Free State to the southwest, and KwaZulu-Natal to the south. The capital is Mbombela. Mpumalanga was formed in 1994, when the area that was the Eastern Transvaal was merged with the former bantustans KaNgwane, KwaNdebele and parts of Lebowa and Gazankulu. Although the contemporary borders of the province were only formed at the end of apartheid, the region and its surroundings has a history that extends back thousands of years. Much of its history, and current significance is as a region of trade. History Precolonial Era Archeological sites in the Mpumalanga region indicate settlement b ...

South Africa
South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. It is bounded to the south by of coastline that stretch along the South Atlantic and Indian Oceans; to the north by the neighbouring countries of Namibia, Botswana, and Zimbabwe; and to the east and northeast by Mozambique and Eswatini. It also completely enclaves the country Lesotho. It is the southernmost country on the mainland of the Old World, and the second-most populous country located entirely south of the equator, after Tanzania. South Africa is a biodiversity hotspot, with unique biomes, plant and animal life. With over 60 million people, the country is the world's 24th-most populous nation and covers an area of . South Africa has three capital cities, with the executive, judicial and legislative branches of government based in Pretoria, Bloemfontein, and Cape Town respectively.

Gauteng
Gauteng ( ) is one of the nine provinces of South Africa. The name in Sotho-Tswana languages means 'place of gold'. Situated on the Highveld, Gauteng is the smallest province by land area in South Africa. Although Gauteng accounts for only 1.5% of the country's land area, it is home to more than a quarter of its population (26%). Highly urbanised, the province contains the country's largest city, Johannesburg, which is also one of the largest cities in the world. Gauteng is the wealthiest province in South Africa and is considered as the financial hub of not only South Africa but the entire African continent, mostly concentrated in Johannesburg. It also contains the administrative capital, Pretoria, and other large areas such as Midrand, Vanderbijlpark, Ekurhuleni and the affluent Sandton.

Encephalartos
''Encephalartos'' is a genus of cycad native to Africa. Several species of ''Encephalartos'' are commonly referred to as bread trees, bread palms or kaffir bread, since a bread-like starchy food can be prepared from the centre of the stem. The genus name is derived from the Greek words ''en'' (within), ''kephalē'' (head), and ''artos'' (bread), referring to the use of the pith to make food. They are, in evolutionary terms, some of the most primitive living gymnosperms. All the species are endangered, some critically, due to their exploitation by collectors and traditional medicine gatherers. The whole genus is listed under CITES Appendix I which prohibits international trade in specimens of these species except for certain non-commercial motives, such as scientific research. Description Several of the species possess stout trunks. In '' E. cycadifolius'', the main trunks are up to high, and several of them may be united at a base where a former main trunk once grew.
