Vegetation Der Erde
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 Pflan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lepidobotryaceae
Lepidobotryaceae is a family of plants in the order Celastrales."Lepidobotryaceae" In: Peter F. Stevens (2001 onwards). Angiosperm Phylogeny Website. In: Missouri Botanical Garden Website. (see External links below). It contains only two species:Klaus Kubitzky. "Lepidobotryaceae" In: Klaus Kubitzki (ed.). ''The Families and Genera of Vascular Plants'' vol.VI. Springer-Verlag: Berlin,Heidelberg, Germany (2004). '' Lepidobotrys staudtii'' (native to tropical Africa) and '' Ruptiliocarpon caracolito'' (native to South and Central America). Description The Lepidobotryaceae are dioecious trees. The leaves are alternate and arranged in two rows along the stems. The blade is elliptical in shape and the margin is entire. The leaves appear simple, but are actually unifoliate. A unifoliate leaf is a type of compound leaf that consists of a single leaflet mounted on the end of a rachis. A joint occurs where the leaflet is attached to the rachis.Glossary In: Peter F. Stevens (2001 onwar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cameroon
Cameroon (; french: Cameroun, ff, Kamerun), officially the Republic of Cameroon (french: République du Cameroun, links=no), is a country in west-central Africa. It is bordered by Nigeria to the west and north; Chad to the northeast; the Central African Republic to the east; and Equatorial Guinea, Gabon and the Republic of the Congo to the south. Its coastline lies on the Bight of Biafra, part of the Gulf of Guinea and the Atlantic Ocean. Due to its strategic position at the crossroads between West Africa and Central Africa, it has been categorized as being in both camps. Its nearly 27 million people speak 250 native languages. Early inhabitants of the territory included the Sao civilisation around Lake Chad, and the Baka hunter-gatherers in the southeastern rainforest. Portuguese explorers reached the coast in the 15th century and named the area ''Rio dos Camarões'' (''Shrimp River''), which became ''Cameroon'' in English.

Linaceae
Linaceae is a family of flowering plants. The family is cosmopolitan, and includes about 250 species in 14 genera, classified into two subfamilies: the Linoideae and Hugonioideae (often recognized as a distinct family, the Hugoniaceae). Leaves of the Linaceae are always simple; arrangement varies from alternate (most species) to opposite (in ''Sclerolinon'' and some ''Linum'') or whorled (in some ''Hesperolinon'' and ''Linum'' species). The hermaphroditic, actinomorphic flowers are pentameric or, very rarely, tetrameric (e.g., ''Radiola linoides'', ''Linum keniense''). In the Linoideae, the largest genus is ''Linum'', the flaxes, with 180–200 species including the cultivated flax, ''Linum usitatissimum''. Members of the Linoideae include herbaceous annuals and perennials, as well as woody subshrubs, shrubs, and small trees (''Tirpitzia'') inhabiting temperate and tropical latitudes of Eurasia, Africa, Australia, and the Americas. The largest genus of the Hugonioideae is ''Hugon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reinhard Gustav Paul Knuth
Reinhard Gustav Paul Knuth (1874–1957) was a German taxonomist, botanist and pteridologist responsible for "''Initia florae venezuelensis''" in 1928, and numerous contributions to Adolf Engler's "''Das Pflanzenreich''" on Geraniaceae, Oxalidaceae, Lecythidaceae, and other families. He worked for more than 50 years at the Botanical Museum in Berlin-Dahlem. As part of his training in plant systematics he visited the herbaria at Kew, Brussels, Geneva, Paris and Utrecht. He was not only a botanist, but was well-versed in zoology, chemistry and geography. While his main interests in botany were systematics and phytogeography, he also ventured into other disciplines and in his final 30 years was working on problems in bacteriology and the growth of Ascomycetes, the source of antibiotics and yeast. His own extensive herbarium collection of some 26 000 specimens was lost when the Dahlem Botanical Museum was destroyed by bombing and fire on the nights of 1 and 2 March 1943. The catastr ...

Oxalidaceae
The Oxalidaceae, or wood sorrel family, are a small family of five genera of herbaceous plants, shrubs and small trees, with the great majority of the 570 species in the genus ''Oxalis'' (wood sorrels). Members of this family typically have divided leaves A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, st ..., the leaflets showing "sleep movements", spreading open in light and closing in darkness. The genus ''Averrhoa'' of which starfruit is a member, is usually included in this family (e.g. APG IV, 2016), but some botanists place it in a separate family Averrhoaceae.

Greek Language
Greek ( el, label=Modern Greek, Ελληνικά, Elliniká, ; grc, Ἑλληνική, Hellēnikḗ) is an independent branch of the Indo-European family of languages, native to Greece, Cyprus, southern Italy (Calabria and Salento), southern Albania, and other regions of the Balkans, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic, and many other writing systems. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting impo ...
