Calodendrum
''Calodendrum'' is a genus of medium-sized evergreen trees comprising two species from Africa. ''Calodendrum capense'', the Cape chestnut, is a well known tree that is widely cultivated, while ''Calodendrum eickii'' is a rare forest tree from Tanzania Tanzania (; ), officially the United Republic of Tanzania ( sw, Jamhuri ya Muungano wa Tanzania), is a country in East Africa within the African Great Lakes region. It borders Uganda to the north; Kenya to the northeast; Comoro Islands .... The botanical name comes from Greek, ''kalos'' means beautiful and ''dendrum'' means tree. Both species are harvested for their timber in Africa.

Calodendrum Capense
''Calodendrum capense'', the Cape chestnut, is an African tree which was first studied at The Cape in South Africa and cultivated widely for its prolific flower display. The tree obtained the common name of "Cape chestnut" because explorer William Burchell saw a resemblance to the horse chestnut in terms of flowers and fruit, though the two are not closely related. Range It is native to a swath of the east side of the continent from the equatorial highlands of Kenya at its northern limit southwards through isolated mountains in Tanzania to both sides of Lake Malawi, the Mashonaland Plateau and Eastern Highlands of Zimbabwe, and then along the lower slopes of the Drakensberg Mountains of South Africa and in coastal forests from Port Elizabeth to Cape Town. Habit The tree can reach 20 metres high in a forest, but in cultivation it is more likely to reach 10 metres, with a spreading canopy. Bark and flowers The trunk is smooth and grey and the leaves are ovate up to 22 cm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calodendrum Eickii
''Calodendrum eickii'' is a rare forest tree from Tanzania which is closely related to the widely cultivated ''Calodendrum capense'', or Cape chestnut. The tree is endemic to montane ''Juniperus'' forest in the West Usambara Mountains where it is under threat from expansion of commercial pine plantation A plantation is an agricultural estate, generally centered on a plantation house, meant for farming that specializes in cash crops, usually mainly planted with a single crop, with perhaps ancillary areas for vegetables for eating and so on.

Cythna Letty
Cythna Lindenberg Letty (1 January 1895, in Standerton – 3 May 1985, in Pretoria), was a South African botanical artist and is regarded as a doyenne of South African botanical art by virtue of the quality and quantity of her meticulously executed paintings and pencil sketches, produced over a period of 40 years with the National Herbarium in Pretoria. Cythna Letty is best remembered for her book ''Wild Flowers of the Transvaal'' which was published in 1962. When decimal currency was introduced in South Africa, she was asked to design the floral motifs for the 10, 20 and 50 cent coins. Besides painting she was an accomplished poet and published ''Children of the Hours'' when she was in her eighties. Cythna was the eldest child of her mother Josina Christina Lindenberg's second marriage and was named after the heroine in Percy Shelley's poem " The Revolt of Islam". The Lettys had five children and for many years the six children from Josina's first marriage were part of an ext ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 bota ...

Adolf Engler
Heinrich Gustav Adolf Engler (25 March 1844 – 10 October 1930) was a German botanist. He is notable for his work on plant taxonomy and phytogeography, such as ''Die natürlichen Pflanzenfamilien'' (''The Natural Plant Families''), edited with Karl A. E. von Prantl. Even now, his system of plant classification, the Engler system, is still used by many herbaria and is followed by writers of many manuals and floras. It is still the only system that treats all 'plants' (in the wider sense, algae to flowering plants) in such depth. Engler published a prodigious number of taxonomic works. He used various artists to illustrate his books, notably Joseph Pohl (1864–1939), an illustrator who had served an apprenticeship as a wood-engraver. Pohl's skill drew Engler's attention, starting a collaboration of some 40 years. Pohl produced more than 33 000 drawings in 6 000 plates for ''Die naturlichen Pflanzenfamilien''. He also illustrated ''Das Pflanzenreich'' (1900–1953), ''Die P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should cl ...

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afric ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tanzania
Tanzania (; ), officially the United Republic of Tanzania ( sw, Jamhuri ya Muungano wa Tanzania), is a country in East Africa within the African Great Lakes region. It borders Uganda to the north; Kenya to the northeast; Comoro Islands and the Indian Ocean to the east; Mozambique and Malawi to the south; Zambia to the southwest; and Rwanda, Burundi, and the Democratic Republic of the Congo to the west. Mount Kilimanjaro, Africa's highest mountain, is in northeastern Tanzania. According to the United Nations, Tanzania has a population of million, making it the most populous country located entirely south of the equator. Many important hominid fossils have been found in Tanzania, such as 6-million-year-old Pliocene hominid fossils. The genus Australopithecus ranged across Africa between 4 and 2 million years ago, and the oldest remains of the genus '' Homo'' are found near Lake Olduvai.
