Agelanthus Rondensis
'' Agelanthus rondensis'' is a species of hemiparasitic plant in the family Loranthaceae. It is endemic to Tanzania. This species has been found only on the Rondo plateau The Rondo Plateau, also known as the Muera Plateau, is a high and extensive massif in the Lindi Region and northern Mtwara Region of southeastern of Tanzania. A portion of the plateau is protected by the Rondo Forest Reserve. It is one of a gro ... in Tanzania where the threat is from conversion of habitat for agriculture. There is a continuing decline in the extent and quality of habitat. This species has not been seen since its discovery in 1903 in what is a well-surveyed region. Thus, it is possibly extinct. No information is available on habitat or host preference. References Endemic flora of Tanzania rondensis Taxa named by Adolf Engler {{Santalales-stub ...

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 ...

Roger Marcus Polhill
Roger is a given name, usually masculine, and a surname. The given name is derived from the Old French personal names ' and '. These names are of Germanic languages, Germanic origin, derived from the elements ', ''χrōþi'' ("fame", "renown", "honour") and ', ' ("spear", "lance") (Hrōþigēraz). The name was introduced into England by the Normans. In Normandy, the Franks, Frankish name had been reinforced by the Old Norse cognate '. The name introduced into England replaced the Old English cognate '. ''Roger'' became a very common given name during the Middle Ages. A variant form of the given name ''Roger'' that is closer to the name's origin is ''Rodger''. Slang and other uses Roger is also a short version of the term "Jolly Roger", which refers to a black flag with a white skull and crossbones, formerly used by piracy, sea pirates since as early as 1723. From up to , Roger was slang for the word "penis". In ''Under Milk Wood'', Dylan Thomas writes "jolly, rodgered" sugges ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Agelanthus
__NOTOC__ ''Agelanthus'' is a genus of Afrotropical plants in family Loranthaceae. They grow in trees, including Acacia and Combretum species, as hemiparasitic shrubs of varying sizes. The host plant is penetrated by a single haustorium, and the stems typically have swollen, flower-producing nodes. The flowers are often closely clustered ( fascicled) with the five petals (pentamerous) fused into a tube (gamopetalous).Flowers of the closely related genus '' Phragmanthera'' are similar in many respects. The flower may have a swollen base and the tubes open along unilateral, V-shaped splits. The filaments remain spirally rolled inward when the flowers open, while the styles are inconspicuous, slender filaments that are somewhat thickened in the middle. Berries range from pink to orange and red in colour, and are around 1 cm in diameter. The genus was first described by Philippe Édouard Léon Van Tieghem in 1895. Species It is the largest genus of the Afrotropical Loranthac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hemiparasitic
A parasitic plant is a plant that derives some or all of its nutritional requirements from another living plant. They make up about 1% of angiosperms and are found in almost every biome. All parasitic plants develop a specialized organ called the haustorium, which penetrates the host plant, connecting them to the host vasculature – either the xylem, phloem, or both. For example, plants like ''Striga'' or ''Rhinanthus'' connect only to the xylem, via xylem bridges (xylem-feeding). Alternately, plants like ''Cuscuta'' and some members of ''Orobanche'' connect to both the xylem and phloem of the host. This provides them with the ability to extract water and nutrients from the host. Parasitic plants are classified depending on the location where the parasitic plant latches onto the host (root or stem), the amount of nutrients it requires, and their photosynthetic capability. Some parasitic plants can locate their host plants by detecting volatile chemicals in the air or soil given ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant
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 lost the ...

Loranthaceae
Loranthaceae, commonly known as the showy mistletoes, is a family of flowering plants. It consists of about 75 genera and 1,000 species of woody plants, many of them hemiparasites. The three terrestrial species are ''Nuytsia floribunda'' (the Western Australian Christmas tree), ''Atkinsonia ligustrina'' (from the Blue Mountains of Australia), and '' Gaiadendron punctatum'' (from Central/South America.) Loranthaceae are primarily xylem parasites, but their haustoria may sometimes tap the phloem, while '' Tristerix aphyllus'' is almost holoparasitic. For a more complete description of the Australian Loranthaceae, seFlora of Australia online, for the Malesian Loranthaceae seFlora of Malesia Originally, Loranthaceae contained all mistletoe species, but the mistletoes of Europe and North America (''Viscum'', ''Arceuthobium'', and ''Phoradendron'') belong to the family Santalaceae. The APG II system 2003 assigns the family to the order Santalales in the clade core eudicots. Phylog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...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. Following the rise of '' Homo erectus'' 1.8 million years ago, humanity spread ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rondo Plateau
The Rondo Plateau, also known as the Muera Plateau, is a high and extensive massif in the Lindi Region and northern Mtwara Region of southeastern of Tanzania. A portion of the plateau is protected by the Rondo Forest Reserve. It is one of a group of dissected plateaus lying between the Mbwemburu and Lukuledi rivers. It is approximately 60 km inland from Lindi, and is situated 15 km north of the Masasi road. It was revealed as an important biodiversity site in studies conducted since the 1980s. Climate The plateaus rise behind a narrow coastal plain. They receive considerable orographic precipitation, making the plateaus cooler and wetter than the surrounding lowlands. The average annual rainfall is 1088 mm (1951-1979), recorded at the Rondo Forest station. The highest rainfall occurs between November and January, and March to May.Perkin, Andrew; Charles Leonard and Nike Doggart (2008). "Landscape Profile: Rondo/Noto".
