Englerophytum Magalismontanum
''Englerophytum magalismontanum'', commonly known as stamvrug, is an evergreen tree that mostly grows in rocky places. It has an extensive range, from northern KwaZulu-Natal northwards along the east coast and into the southern African interior, and northwards into tropical Africa. Nomenclature ''E. magalismontanum'' was at various times in the past known under the names ''Bequaertiodendron magalismontanum'' (see: J. C. Bequaert), ''Pouteria magalismontana'' and ''Chrysophyllum magalismontanum''. The specific name refers to the Magaliesberg from where the species was first described, and where it commonly occurs. Description This tree is usually known by its Afrikaans name ''stamvrug'' ("stem fruit") which refers to its habit of bearing densely clustered fruit on the trunk and thicker branches (cauliflory), a common feature of this family. The fruit are tasty and sweet with very little pink flesh - they are rich in latex and are leathery-skinned. The seed is large, smooth and h ...

KwaZulu-Natal
KwaZulu-Natal (, also referred to as KZN) is a Provinces of South Africa, province of South Africa that was created in 1994 when the government merged the Zulu people, Zulu bantustan of KwaZulu ("Place of the Zulu" in Zulu language, Zulu) and Natal Province. It is located in the southeast of the country, with a long shoreline on the Indian Ocean. It shares borders with three other provinces and the countries of Mozambique, Eswatini and Lesotho. Its capital is Pietermaritzburg, and its largest city is Durban, which is also the Port of Durban, city with the largest port in sub-saharan Africa. It is the second-most populous province in South Africa, after Gauteng. Two areas in KwaZulu-Natal have been declared UNESCO World Heritage Sites: the iSimangaliso Wetland Park and the uKhahlamba Drakensberg Park. These areas are important to the surrounding ecosystems. During the 1830s and early 1840s, the northern part of what is now KwaZulu-Natal was established as the Zulu Kingdom. The ...

Magaliesberg
The Magaliesberg (historically also known as ''Macalisberg'' or ''Cashan Mountains'') of northern South Africa, is a modest but well-defined mountain range composed mainly of quartzites. It rises at a point south of the Pilanesberg (and the Pilanesberg National Park) to form a curved prominence that intersects suburban Pretoria before it peters out some to the east, just south of Bronkhorstspruit. The highest point of the Magaliesberg is reached at Nooitgedacht, about above sea level. A cableway reaching to the top of the mountain range is located at Hartbeespoort Dam, providing sweeping views of the Magaliesberg and surrounding area. Geology The Magaliesberg has ancient origins. Its composition is ascribed to successive geological processes over a very protracted history. Its quartzites, shales, chert and dolomite were deposited as sediments in an inland basin on top of a 3 billion year old Archaean Basement Complex, known as the Kaapvaal craton. This process of sedi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cauliflory
Cauliflory is a botanical term referring to plants that flower and fruit from their main stems or woody trunks, rather than from new growth and shoots. It is rare in temperate regions but common in tropical forests. There have been several strategies to distinguish among types of cauliflory historically, including the location or age of branch where inflorescences grow, whether inflorescences attach to stolons or branches, and whether Nodes (botany), axillary nodes or Adventitious, adventitious nodes develop into Meristem, reproductive tissues. Cauliflory is a non-Homology (biology), homologous phenomenon with several different sources of development and evolutionary value. The development of buds in axillary cauliflorous species occurs through either the re-use of the same position or old tissue over seasons of growth or Bud break, release from dormancy. In both cases, Vascular tissue, vascularization of the bud must occur from pre-existing tissue, such as the pith. In ''Cerc ...

Mimusops Zeyheri
''Mimusops zeyheri'' is a medium-sized (up to 15m) evergreen tree belonging to the family Sapotaceae and widely distributed in rocky places from the east coast of southern Africa, inland and northwards to tropical Africa.

Gutta-percha
Gutta-percha is a tree of the genus ''Palaquium'' in the family Sapotaceae, which is primarily used to create a high-quality latex of the same name. The material is rigid, naturally biologically Chemically inert, inert, resilient, electrically nonconductor, nonconductive, and thermoplastic, most commonly sourced from ''Palaquium gutta''; it is a polymer of isoprene which forms a rubber-like elastomer. The word "gutta-percha" comes from the plant's name in Malay language, Malay: translates as 'sticky gum' and () is the name of a less-sought-after gutta tree. The western term therefore is likely a derivative amalgamation of the original native names. Description ''Palaquium gutta'' trees are tall and up to in trunk diameter. The leaves are evergreen, alternate or spirally arranged, simple, entire, long, glossy green above, and often yellow or glaucous below. The flowers are produced in small clusters along the stems, each flower with a white corolla (flower), corolla with f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Balatá
''Manilkara bidentata'' is a species of ''Manilkara'' native to a large area of northern South America, Central America and the Caribbean. Common names include bulletwood, balatá, ausubo, massaranduba, quinilla, and (ambiguously) " cow-tree". Description The balatá is a large tree, growing to tall. The leaves are alternate, elliptical, entire, and long. The flowers are white, and are produced at the beginning of the rainy season. The fruit is a yellow berry, in diameter, which is edible; it contains one (occasionally two) seed(s). Its latex is used industrially for products such as chicle. Uses The latex is extracted in the same manner in which sap is extracted from the rubber tree. It is then dried to form an inelastic rubber-like material. It is almost identical to gutta-percha (produced from a closely related southeast Asian tree), and is sometimes called ''gutta-balatá''. Balatá was often used in the production of high-quality golf balls, to use as the outer layer o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trees Of South Africa
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller palms, tree ferns, bananas, and bamboos. Trees are not a monophyletic taxonomic group but consist of a wide variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are around three trillion mature trees in the world currently. A tree typically has many secondary branches supported clear of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
