Entandrophragma Cylindricum
''Entandrophragma cylindricum'' is a tree of the genus ''Entandrophragma'' of the family ''Meliaceae''. It is commonly known as sapele or sapelli ( ) or sapele mahogany, as well as aboudikro, assi, and muyovu. Origin of the name The name ''sapele'' comes from that of the city of Sapele in Nigeria, where there is a preponderance of the tree. African Timber and Plywood (AT&P), a division of the United Africa Company, had a factory at this location where the wood, along with ''Triplochiton scleroxylon'', ''Obeche'', mahogany, and Khaya was processed into timber which was then exported from the Port of Sapele worldwide. The name of the city itself is said to be an anglicisation of the Urhobo word Uriapele, commemorating a local deity. It is believed the British colonial authorities changed the name of the then hamlet to Sapele as it was easier to pronounce. Description ''Entandrophragma cylindricum'' is native to tropical Africa. There are protected populations and felling restr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...

Entandrophragma Caudatum
''Entandrophragma caudatum'', or mountain mahogany, is a large Southern African tree belonging to the Meliaceae, mahogany family and found in eastern and north eastern South Africa, Eswatini, Botswana, Angola, the Caprivi Strip region of Namibia, Zimbabwe, Zambia and Malawi.

This is a large deciduous tree up to 20m in height, found at low altitudes in river valleys, but also in open woodland on rocky slopes and ridges. Bark is grey, flaking in large, irregular scales and revealing a buff surface, giving a mottled appearance. The leaves up to 25 cm long, puberulous, crowded near the ends of branches, paripinnately compound with 6 or 7 pairs of leaflets, each leaflet measuring up to 11 x 3.5 cm. The leaflets are hairless with a narrowly attenuate apex or drip-tip, and entire margin. Petioles are some 20mm in length and slend ...

Adolf Engler
Heinrich Gustav Adolf Engler (25 March 1844 – 10 October 1930) was a German botanist. He is notable for his work on alpha taxonomy, plant taxonomy and phytogeography, such as ''Die natürlichen Pflanzenfamilien'' (''The Natural Plant Families''), edited with Karl Anton Eugen Prantl, Karl A. E. von Prantl. Even now, his system of plant classification, the Engler system, is still used by many Herbarium, herbaria and is followed by writers of many manuals and Flora (plants), 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 ...

Hermann Harms
Hermann August Theodor Harms (16 July 1870 – 27 November 1942) was a German taxonomist and botanist. Harms was born in Berlin. He worked as a botanist at the Berlin-Dahlem Botanical Garden and Botanical Museum, Botanical Museum in Berlin. He was a member of the Prussian Academy of Sciences. He died in Berlin, aged 52. He was longtime editor of Adolf Engler's "''Das Pflanzenreich''", and was the author of several chapters on various plant families in Engler and Carl Prantl, Prantl's "''Die Natürlichen Pflanzenfamilien''", including the chapters on Bromeliaceae (1930) and Nepenthaceae (1936). In the latter he revised the pitcher plant genus ''Nepenthes'', dividing it into three subgenera: ''Anurosperma'', ''Eunepenthes'' and ''Mesonepenthes'' (see Taxonomy of Nepenthes, Taxonomy of ''Nepenthes''). Furthermore, he was interested in the genus ''Passiflora''. The plant genera ''Harmsia'' (Schum.), ''Harmsiella'' (John Isaac Briquet, Briq.), ''Harmsiodoxa'' (in the Brassicacea ...

Friedrich Welwitsch
Friedrich Martin Josef Welwitsch (25 February 1806 – 20 October 1872) was an Austrian explorer and botanist who in Angola was the first European to describe the plant ''Welwitschia mirabilis''. His report received wide attention among the botanists and general public, comparable only to the discovery of two other plants in the 19th century, namely ''Victoria amazonica'' and ''Rafflesia arnoldii''.Strlič, Matija. "Dr. Friderik Velbič, 1806–1872". ''Proteus, the journal of the Natural Sciences Society of Slovenia''. Year 61, No. 9/10 (pp. 396-404). ISSN 0033-1805. In Angola, Welwitsch also discovered ''Rhipsalis baccifera'', the only cactus species naturally occurring outside the New World. It was found a few years later in Sri Lanka too, which reignited the now already one-and-a-half-century-old debate on the origin of cacti in Africa and Asia. At the time, the debate concluded with the conviction of numerous authors that they were introduced and spread by migratory bird ...

Entandrophragma Angolense
''Entandrophragma angolense'', called the ''tiama'', is a tree species with alternate, pinnately compound leaves that are clustered at the ends of branches. It is within the family Meliaceae and has a wide distribution area, occurring in moist semi-deciduous and evergreen forest regions of Tropical Africa from Sierra Leone to Uganda. Harvesting for timber has caused the species to become vulnerable in certain countries. Taxonomy ''Entandrophragma angolense'' was first indicated as belonging to the Swietenia family but upon a revision in 1894 by de Candolle, the species was transferred to a new genus Entandrophragma. In 2021, up to 10 taxa are placed as synonyms of the species in two database. Description The tree can grow to a height of 60 meters and reach a diameter of 200 cm, its base often has developed buttresses that can reach a height of 6 meters, and extending as surface roots, the trunk is branchless for up to 30 meters. The grey-brown bark tends to be thin and s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
