Babiana Pygmaea
''Babiana pygmaea'' is a perennial plant of about high that annually forms leaves and flowers from an underground corm that is assigned to the Iridaceae, iris family. It has bowl-shaped, pale yellow flowers with six perianth lobes, purplish in its heart, emerging from a cylindrical tube, and lance-shaped, pleated and heary leafblades that are almost at a right angle with the sheaths. The species can be found in the Western Cape province of South Africa. It is called geelbobbejaantjie in Afrikaans. Description Geelbobbejaantjie is a geophyte with an egg-shaped, underground corm from which annually the leaves and stems appear above ground, forming a plant of about high including the leaves. The stem is upright, seldomly branched and covered in velvety hairs. The Leaf#Morphology, leaf blades are pleated, softly hairy and lance-shaped wide. The blade sits at an almost right angle atop a sheath that envelops the sheaths of higher leaves. The unscented flowers sit with two to five ...

Kurt Polycarp Joachim Sprengel
Kurt Polycarp Joachim Sprengel (3 August 1766 – 15 March 1833) was a German botanist and physician who published an influential multivolume history of medicine, ''Versuch einer pragmatischen Geschichte der Arzneikunde'' (1792–99 in four volumes with later editions running to five) and several other medical reference works. Biography Sprengel was born at Boldekow in Pomerania, and he is considered of German nationality. His father, a clergyman, provided him with a thorough education of wide scope; as boy he distinguished himself as a linguist, in Latin and Greek, and also Arabic; his uncle, Christian Konrad Sprengel (1750–1816), is remembered for his studies in the fertilization of flowers by insects – a subject in which he reached conclusions many years ahead of his time. Spreng. appeared as an author at the age of fourteen, publishing a small work called '' Anleitung zur Botanik für Frauenzimmer'' ("guide to botany for women") in 1780. In 1784 he began to study the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Flora Of South Africa
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Babiana
''Babiana'' ()''Sunset Western Garden Book'', 1995:606–607 is a genus of geophytes in the family Iridaceae with 93 recognized species . The leaves consist of a stalk and a blade that are at an angle to each other. The leaf blades are entire, laterally flattened and pleated, and often hairy. Each individual flower is subtended by two hairy or smooth bracts that are green in most species. The outer bract is often the largest of the two. In most species the bracts have a dry, brown tip, but in a few species it is entirely green or entirely dry when flowering or the outer bract is translucent and has a papery texture. The inner bract (between the flower and the stem) is forked or split all the way to its base. Each flower is without a pedicel, with six tepals that are merged at their base into a tube and form a perianth that is mirror-symmetrical in most species, with three anthers implanted where the perianth tube widens and that are, in almost every species, clustered at one side o ...

Acacia
''Acacia'', commonly known as the wattles or acacias, is a large genus of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa and Australasia. The genus name is New Latin, borrowed from the Greek (), a term used by Dioscorides for a preparation extracted from the leaves and fruit pods of ''Vachellia nilotica'', the original type of the genus. In his ''Pinax'' (1623), Gaspard Bauhin mentioned the Greek from Dioscorides as the origin of the Latin name. In the early 2000s it had become evident that the genus as it stood was not monophyletic and that several divergent lineages needed to be placed in separate genera. It turned out that one lineage comprising over 900 species mainly native to Australia, New Guinea, and Indonesia was not closely related to the much smaller group of African lineage that contained ''A. nilotica''—the type species. This meant that the Australasian lineage (by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...

Swartland
The Swartland is a region of Western Cape Province that begins some north of Cape Town and consists of the area between the towns of Malmesbury in the south, Darling in the west, Piketberg in the north, Moorreesburg in the middle and the Riebeek West and Riebeek Kasteel in the east. Jan van Riebeeck called this softly undulating country between the mountain ranges "Het Zwarte Land" (the Black Land) because of the endemic Renosterbos (''Elytropappus rhinocerotis''). After the rains, mainly in winter, the Renosterbos takes on a dark appearance when viewed from the distance in large numbers. This is due to the fine leaf-hairs adhering to the leaves when wet. The wide fertile plain is the bread basket of Cape Town with its wheat fields reaching up to the foot of the mountains, interrupted by wine, fruit, and vegetable farms. In Moorreesburg can be found only one of two museums in the world that shows the history of wheat farming. Viticulture in the Swartland is still comparatively y ...

Renosterveld
Renosterveld is a term used for one of the major plant communities and vegetation types of the Cape Floristic Region (Cape Floral Kingdom) which is located in southwestern and southeastern South Africa, in southernmost Africa. It is an ecoregion of the Mediterranean forests, woodlands, and scrub biome. Etymology Renosterveld directly translated in the Afrikaans language means "rhinoceros-field", a possible reference to the high number of rhinoceroses seen by the Afrikaner settlers at the time. It may also derive its name from the renosterbos ("rhinoceros bush - ''Elytropappus rhinocerotis''), which is a common species of shrub found here. The dull grey colour of renosterbos is similar to the colour of a rhino's hide. Geology Renosterveld plants grow on rich soil, which makes them more nutritious than typical fynbos plants. Typically, renosterveld is largely confined to fine-grained soils - mainly clays and silts - which are derived from the shales of the Malmesbury and Bokkeve ...

Darling, South Africa
Darling is a small town in a farming area on the west coast region of the Western Cape, about 75 km (46.6 mi) from Cape Town. At the beginning of the 18th century about 29 farmers lived in an area called Groenkloof and on one of these farms, Langfontein, Darling was founded in 1853. It was named after Sir Charles Henry Darling who came in 1851 to the Cape as Lieutenant Governor. The Darling Museum shows the history of the town and the Darling creamery which was established in 1899 by two Swedish settlers, Nils Georg Moller and G. Threnstrom, and was closed in 1950. The museum also holds a collection of large agricultural machines. Darling is famous for its wildflowers and since 1917 the annual Darling Wildflower show is held by the Darling Wildflower Society, founded in 1915 by Mrs. Suzanne Malan and Mr. Frederick Duckitt of Waylands. The Darling Wind Farm is situated between Darling and the coastal town of Yzerfontein and it is operational with plans for expansion. T ...
