Pteronia Glauca
''Pteronia glauca'' ("Geelboegoekaroo") is a species of flowering plant in the family Asteraceae, indigenous to the Karoo regions of South Africa. Description A shrub of roughly 60 cm, usually with downwards-drooping outer branches (especially when growing in very rocky ground). Branches can root where they touch the ground. It has small (5x3mm), light grey, woolly, fragrant leaves, and forms a low, dense bush. The flowerheads appear in Spring, at the tips of the branches. They are yellow and small (5mm wide), with non-sticky yellow bracts. Relatives It often co-occurs with its close relatives, '' Pteronia paniculata'' or '' Pteronia pallens'', both of which have distinctive yellow-green leaves. ''Pteronia incana'' ("Ash-bush") is a very similar species, which also has light grey leaves. However, unlike ''P.glauca'', its outer branches are not down-curved. Distribution and habitat The distribution of this species is across the arid interior Karoo regions of South Africa. I ...

Carl Peter Thunberg
Carl Peter Thunberg, also known as Karl Peter von Thunberg, Carl Pehr Thunberg, or Carl Per Thunberg (11 November 1743 – 8 August 1828), was a Swedish naturalist and an "apostle" of Carl Linnaeus. After studying under Linnaeus at Uppsala University, he spent seven years travelling in southern Africa and Asia, collecting and describing many plants and animals new to European science, and observing local cultures. He has been called "the father of South African botany", "pioneer of Occidental Medicine in Japan", and the "Japanese Linnaeus". Early life Thunberg was born and grew up in Jönköping, Sweden. At the age of 18, he entered Uppsala University where he was taught by Carl Linnaeus, regarded as the "father of modern taxonomy". Thunberg graduated in 1767 after 6 years of studying. To deepen his knowledge in botany, medicine and natural history, he was encouraged by Linnaeus in 1770 to travel to Paris and Amsterdam. In Amsterdam and Leiden Thunberg met the Dutch botanist ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ...

Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technicall ...

Karoo
The Karoo ( ; from the Afrikaans borrowing of the South Khoekhoe !Orakobab or Khoemana word ''ǃ’Aukarob'' "Hardveld") is a semi-desert natural region of South Africa. No exact definition of what constitutes the Karoo is available, so its extent is also not precisely defined. The Karoo is partly defined by its topography, geology and climate, and above all, its low rainfall, arid air, cloudless skies, and extremes of heat and cold.Potgieter, D.J. & du Plessis, T.C. (1972) ''Standard Encyclopaedia of Southern Africa''. Vol. 6. pp. 306–307. Nasou, Cape Town.''Reader’s Digest Illustrated Guide to Southern Africa''. (5th Ed. 1993). pp. 78–89. Reader’s Digest Association of South Africa Pty. Ltd., Cape Town. The Karoo also hosted a well-preserved ecosystem hundreds of million years ago which is now represented by many fossils. The ǃ’Aukarob formed an almost impenetrable barrier to the interior from Cape Town, and the early adventurers, explorers, hunters, and travelers o ...

Pteronia Paniculata
''Pteronia paniculata'' ("Gombos" or "gum-bush") is a species of flowering plant in the family Asteraceae, indigenous to the Karoo regions of South Africa. Description This aromatic species has sticky leaves but, unlike some other ''Pteronia'' species, the flowers are not sticky. It has slender, furrowed, needle, incurved, green leaves, held in opposite pairs. It forms clusters of flowers (several capitula) at the tips of its branches. This helps to distinguish it from the otherwise similar species ''Pteronia pallens''. Distribution This species is widespread, occurring from Namibia to the Robertson Karoo in the south, as well as eastwards into the Eastern Cape. Its natural habitat is dry, rocky apronveld and it is extremely common. Due to its being inedible for livestock, it achieves unnatural densities in areas that are overgrazed. It often cooccurs with its close relatives, ''Pteronia pallens'' or ''Pteronia incana ''Pteronia incana'' ("Asbos" or "ash-bush") is a sp ...

Pteronia Pallens
''Pteronia pallens'' ("Scholtzbos" or "Aasvoëlbos / Witbas") is a species of flowering plant in the family Asteraceae, indigenous to the Karoo regions of South Africa. Its natural habitat is dry, rocky slopes. It often cooccurs with its close relatives, ''Pteronia paniculata'' or ''Pteronia incana''. Description A small shrub with pale woody stem. The leaves are slender, blunt-ended, channeled and green. One to three rounded, discoid flower heads appear at the tips of the branches. This helps to distinguish it from the otherwise similar species ''Pteronia paniculata''. Distribution This species occurs in the western Little Karoo, the western Great Karoo and into the Northern Cape Province. It usually grows on lower slopes on silt or sand that is often calciferous (often overlying calcrete). References

Eastern Cape Province
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 Mandela, Wal ...
