Cylicomorpha Parviflora
''Cylicomorpha'' is a plant genus consisting of two species that are native to the African tropics. They are the only African representatives of the Caricaceae, and are consequently related to the papaya. Habit and appearance They have the habit of bottle trees, and their soft, dilated trunks are armed with short conical spines. The leaves are digitately lobed. They are strictly dioecious, and like all Caricaceae, produce abundant milky sap when damaged. The inflorescences are axillary. The male panicles hold many flowers, while the female flowers are solitary or borne in small numbers on short racemes. Species Range and occurrence They occur as tall-growing, pioneer plants in moist submontane habitats, where they are local but gregarious. The western species, ''C. solmsii'' is locally threatened by clearance for agriculture and wood, and may be extinct at Mount Cameroon and at Barombi, Kumba Kumba is a metropolitan city in the Meme department, Southwest Region, We ...

Ignatz Urban
Ignatz Urban (7 January 1848 – 7 January 1931) was a German botanist. He is known for his contributions to the flora of the Caribbean and Brazil, and for his work as curator of the Berlin Botanical Garden. Born the son of a brewer, Urban showed an interest in botany as an undergraduate. He pursued further study at the University of Bonn and later at the University of Berlin where he gained a doctorate in 1873. Urban was appointed by A. W. Eichler to run the Berlin Botanical Garden and supervised its move to Dahlem. He also worked as Eichler's assistant on the ''Flora Brasiliensis'', later succeeding him as editor. In 1884 Urban began working with Leopold Krug on his Puerto Rican collections, a collaboration would later produce the nine-volume '' Symbolae Antillanae'', one of his most important contributions, and his 30-part ''Sertum Antillanum''. Urban's herbarium, estimated to include 80,000 or more sheets, was destroyed when the Berlin Herbarium was bombed in 1943 ...

Caricaceae
The Caricaceae are a family of flowering plants in the order Brassicales, found primarily in tropical regions of Central and South America and Africa. They are usually short-lived evergreen pachycaul shrubs or small to medium-sized trees growing to 5–10 m tall. One species, ''Vasconcellea horovitziana'' is a liana and the three species of the genus '' Jarilla'' are herbs. Some species, such as the papaya, bear edible fruit and produce papain. Based on molecular analyses, this family has been proposed to have originated in Africa in the early Cenozoic era, ~66 million years ago (mya). The dispersal from Africa to Central America occurred ~35 mya, possibly via ocean currents from the Congo delta. From Central America, the family reached South America 19-27 mya. The family comprises six genera and about 34-35 species: *''Carica'' – one species, ''Carica papaya'' ( papaya), Americas *''Cylicomorpha'' – two species, Africa *''Horovitzia'' – one species, Mexico *''Jacar ...

Papaya
The papaya (, ), papaw, () or pawpaw () is the plant species ''Carica papaya'', one of the 21 accepted species in the genus ''Carica'' of the family Caricaceae. It was first domesticated in Mesoamerica, within modern-day southern Mexico and Central America. In 2020, India produced 43% of the world supply of papayas. Etymology The word ''papaya'' comes from Arawak via Spanish, this is also where ''papaw'' and ''pawpaw'' come from. Description The papaya is a small, sparsely branched tree, usually with a single stem growing from tall, with spirally arranged leaves confined to the top of the trunk. The lower trunk is conspicuously scarred where leaves and fruit were borne. The leaves are large, in diameter, deeply palmately lobed, with seven lobes. All parts of the plant contain latex in articulated laticifers. Flowers Papayas are dioecious. The flowers are five-parted and highly dimorphic; the male flowers have the stamens fused to the petals. The female flowers h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dioecy
Dioecy (; ; adj. dioecious , ) is a characteristic of a species, meaning that it has distinct individual organisms (unisexual) that produce male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is biparental reproduction. Dioecy has costs, since only about half the population directly produces offspring. It is one method for excluding self-fertilization and promoting allogamy (outcrossing), and thus tends to reduce the expression of recessive deleterious mutations present in a population. Plants have several other methods of preventing self-fertilization including, for example, dichogamy, herkogamy, and self-incompatibility. Dioecy is a dimorphic sexual system, alongside gynodioecy and androdioecy. In zoology In zoology, dioecious species may be opposed to hermaphroditic species, meaning that an individual is either male or female, in which case the synonym gonochory is more often used. Most animal species are dioecious (gon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foothills
Foothills or piedmont are geographically defined as gradual increases in elevation at the base of a mountain range, higher hill range or an upland area. They are a transition zone between plains and low relief hills and the adjacent topographically higher mountains, hills, and uplands. Frequently foothills consist of alluvial fans, coalesced alluvial fans, and dissected plateaus. Description Foothills primarily border mountains, especially those which are reached through low ridges that increase in size closer and closer to the mountain, but can also border uplands and higher hills. Examples Areas where foothills exist, or areas commonly referred to as the foothills, include the: *Sierra Nevada foothills of California, USA *Foothills of the San Gabriel Valley in Los Angeles County, California, USA *Rocky Mountain Foothills in British Columbia and Alberta, Canada *Silesian Foothills in Silesia, Poland *Sivalik Hills along the Himalayas in the Indian subcontinent * Catalin ...

Mount Cameroon
Mount Cameroon is an active volcano in the South West region of Cameroon next to the city of Buea near the Gulf of Guinea. Mount Cameroon is also known as Cameroon Mountain or Fako (the name of the higher of its two peaks) or by its indigenous name ''Mongo ma Ndemi'' ("Mountain of Greatness"). It is the highest point in sub-Saharan western and central Africa, the fourth-most prominent peak in Africa, and the 31st-most prominent in the world. The mountain is part of the area of volcanic activity known as the Cameroon Volcanic Line, which also includes Lake Nyos, the site of a disaster in 1986. The most recent eruption occurred on February 3, 2012. Description Mount Cameroon is one of Africa's largest volcanoes, rising to above the coast of west Cameroon. It rises from the coast through tropical rainforest to a bare summit, which is cold, windy, and occasionally dusted with snow. The massive steep-sided volcano of dominantly basaltic-to-trachybasaltic composition forms a volc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kumba
Kumba is a metropolitan city in the Meme department, Southwest Region, Western Cameroon, referred as "K-town" in local slang. Kumba is the most developed and largest city in the Meme Department and has attracted people from the local villages like Mbonge, Ekondo Titi, etc. Kumba has an estimated population of about 400,000 with three quarters of this population being youth. As a result of improvement in infant health care, rural-urban migration and infant mortality is falling while birthrates rise, causing the population of Kumba to increase. The N8 and N16 highways meet at Kumba. Etymology The name 'Kumba' originates from the Bafo word 'kumbè', meaning an umbrella tree History According to local mythology, Kumba was founded by the hunter Midiki Bokeng, In his honour a monument has been put up around the Town Green. Kumba was originally a Bafo tribal capital formed after the Mediki wars. Mediki was a Bafo native sent by the Bafo chief Nguti to fight other tribes aro ...

Flora Of Africa
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brassicales Genera
The Brassicales (or Cruciales) are an order of flowering plants, belonging to the eurosids II group of dicotyledons under the APG II system. One character common to many members of the order is the production of glucosinolate (mustard oil) compounds. Most systems of classification have included this order, although sometimes under the name Capparales (the name chosen depending on which is thought to have priority). The order typically contains the following families: * Akaniaceae – two species of turnipwood trees, native to Asia and eastern Australia * Bataceae – salt-tolerant shrubs from America and Australasia * Brassicaceae – mustard and cabbage family; may include the Cleomaceae * Capparaceae – caper family, sometimes included in Brassicaceae * Caricaceae – papaya family * Cleomaceae * Gyrostemonaceae – several genera of small shrubs and trees endemic to temperate parts of Australia * Koeberliniaceae – one species of thorn bush native to Mexico and the US Sout ...
