Encephalartos Kisambo
''Encephalartos kisambo'' is a species of cycad in the family Zamiaceae. It is known as the Voi cycad. This species is distributed in the cloud forests of the steep mountain hills at the border of southern Kenya and northern Tanzania. Most grow in misty forest habitat, and some grow on drier rock cliffsides. Some subpopulations are threatened by habitat loss to charcoal production and agriculture, and the species is threatened by overcollection. Description Encephalartos kisambo is an arborescent species, with pachycaulous barrel-shaped trunks, with a stem 1.2-2 m high, erect or sometimes decombent, 45-52 cm in diameter. The pinnate dark green dioecious leaves, arranged like a crown at the apex of the stem, are 240–360 cm long, silvery-green to bluish-green in color, with a 2.5–5 cm long petiole. They are formed by 89-96 pairs of oblong-lanceolate leaflets, opposite, 24–37 cm long and 29–37 mm broad, of leathery consistency, with spiny margin, inserted on the rachis ...

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. Following the rise of '' Homo erectus'' 1.8 million years ago, humanity spread ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Kenya
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] |
Plants Described In 1990
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have los ...

Encephalartos
''Encephalartos'' is a genus of cycad native to Africa. Several species of ''Encephalartos'' are commonly referred to as bread trees, bread palms or kaffir bread, since a bread-like starchy food can be prepared from the centre of the stem. The genus name is derived from the Greek words ''en'' (within), ''kephalē'' (head), and ''artos'' (bread), referring to the use of the pith to make food. They are, in evolutionary terms, some of the most primitive living gymnosperms. All the species are endangered, some critically, due to their exploitation by collectors and traditional medicine gatherers. The whole genus is listed under CITES Appendix I which prohibits international trade in specimens of these species except for certain non-commercial motives, such as scientific research. Description Several of the species possess stout trunks. In '' E. cycadifolius'', the main trunks are up to high, and several of them may be united at a base where a former main trunk once grew.

Morogoro
Morogoro is a city in the eastern part of Tanzania west of Dar es Salaam. Morogoro is the capital of the Morogoro Region. It is also known informally as "Mji kasoro bahari" which translates to “city short of an ocean/port." The Belgian based non-profit, APOPO trains Gambian pouched rats known as HeroRATS for landmine detection, and detection of tuberculosis in Morogoro. Morogoro lies at the base of the Uluguru Mountains and is a centre of agriculture in the region. The Sokoine University of Agriculture is based in the city. A number of missions are also located in the city, providing schools and hospitals. Morogoro is home to the Amani Centre, which has helped over 3,400 disabled people in the surrounding villages. Water supply Eighty percent of Morogoro's water supply comes from the Mindu Dam on the Ngerengere River. The dam project, begun in 1978, has been controversial. The lake behind the dam has led to high rates of bilharzia infection, and mercury run-off from gold min ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...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] |
Pachycaul
Pachycauls are plants with a disproportionately thick Trunk (botany), trunk for their height, and few branches. This can be the product of exceptional primary growth (as with Arecaceae, palms and cycads) or disproportioate secondary growth as with Adansonia. The word is derived from the Greek language, Greek ''pachy-'' meaning thick or stout, and Latin language, Latin ''caulis'' meaning the stem. All of the tree (and treelike) species of cactus are pachycauls, as are most Arecaceae, palms, Cycads and pandans. The most extreme pachycauls are the floodplains, or riverbottom variety of the African Palmyra (Borassus aethiopum) with primary growth up to seven feet (2.1 meters) in thickness, and the Coquito Palm (Jubaea chilensis) with primary growth up to six feet (1.8 meters) thick. The most pachycaulous cycad is Cycas thouarsii at up to five feet (150 centimeters) in diameter. The tallest pachycaul is the Andean Wax Palm (Ceroxylon quindiuense) at up to 220 feet (66 meters). and abo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
