List Of Southern African Indigenous Trees
This is a list of Southern African trees, shrubs, suffrutices, geoxyles and Liana, lianes, and is intended to cover Angola, Botswana, Eswatini, Lesotho, Malawi, Mozambique, Namibia, South Africa, Zambia and Zimbabwe. The notion of 'indigenous' is of necessity a blurred concept, and is clearly a function of both time and political boundaries. The global distribution of plants useful to humans, or inadvertently transported by them, is closely linked to a mapping of their journeys and settlements, and the movement of species in prehistoric times must be inferred from archaeological and palaeontological remains, Center of origin, centers of diversity, DNA samples and other sources.

Silvertree Leucadendron Foliage - Cecilia Forest - Cape Town 1
''Leucadendron argenteum'' (silver tree, silver leaf tree, , or ) is an endangered plant species in the family Proteaceae, which is endemic (ecology), endemic to a small area of the Cape Peninsula, South Africa. Most grow in and around the city of Cape Town, but outlying (perhaps introduced) populations exist near Somerset West (Silwerboomkloof), Paarl and Stellenbosch. It is a protected tree in South Africa. Appearance The silvertree is a striking evergreen tree, growing 5–7 m tall (sometimes up to 16 m). It is erect and well-proportioned with a thick, straight trunk and grey bark. The soft, silky leaf, leaves are shiny silver, lanceolate, 8–15 cm long and 2 cm broad, with their distinct silvery sheen produced by dense velvety hairs. The wind-pollinated flowers are produced in dense pink, globose inflorescences 4–5 cm diameter, and give off a pleasant scent. Like all Leucadendrons, this tree is plant sexuality, dioecious, with separate male and female plan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Encephalartos Ghellinckii
''Encephalartos ghellinckii'' Lem. or Drakensberg cycad is endemic to South Africa, and is one of about 70 species found in sub-Saharan Africa. Strongly associated with the Natal Drakensberg, this 3m tall evergreen species is found from the foothills to fairly high altitudes, growing on stream banks, steep grassy slopes ansandstone outcrops Its preferred habitat lying within grassveld, it has developed resistance to veldfires, and also the intense cold brought on by snow and frost. Distribution It is found in three distinct and separate areas in KwaZulu-Natal and northern Transkei. Plants from the high-altitude areas are more robust and usually have a fire-scarred base. The low altitude plants, such as those near the Umkomaas River, are stunted or dwarf-like and may have up to five trunks, often blackened by grass fires, which are thought to stimulate leaf and cone production.

Encephalartos Ferox
''Encephalartos ferox'', a member of the family Zamiaceae, is a small cycad with 35 cm wide subterranean trunk. It gets its name from the Latin word ferocious, likely from the spine-tipped lobes on the leaves of the plant.Norstog, Knut J., and Trevor J. Nicholls. The Biology of the Cycads. New York : Cornell University Press, 1997. It is found naturally on the south-eastern coast of Africa where it has been used by local people for its starch content.Jones, David L. Cycads of the World. Australia: Reed Books, 1993. It is considered to be one of the most popular cultivated cycads. Naming The species was first described in 1851 when material was collected from Mozambique. After looking at material found in Colony of Natal, Natal, South Africa, it was redescribed as ''E. kosiensis'' Hutchinson. After looking more carefully at the material, the original name was kept, and the redescribed name was no longer used. Habitat ''E. ferox'' is found along the southern coast of ...
