Nuriaea Engleriana
''Nuriaea'' is a genus of flowering plants in the sunflower family, Asteraceae. It includes two species of thistles, '' Nuriaea dender'' and '' Nuriaea engleriana'', which are endemic to Ethiopia. They are spiny perennial herbs, growing 3 to 4 meters tall and occasionally up to 5 meters. Both species are native to the Ethiopian Highlands, growing in Afromontane plant communities above 1,600 meters elevation. These species were formerly placed in genus ''Cirsium''. They have a plumose pappus like species of ''Cirsium'' and '' Afrocirsium''. They differ from these other genera in their large size, and in having large capitula (4–7 cm) which resemble those of ''Cynara ''Cynara'' is a genus of thistle-like perennial plants in the family Asteraceae.

Cirsium
''Cirsium'' is a genus of Perennial plant, perennial and Biennial plant, biennial flowering plants in the Asteraceae, one of several genera known commonly as thistles. They are more precisely known as plume thistles. These differ from other thistle genera (''Carduus'', ''Silybum'' and ''Onopordum'') in having a seed with a Pappus (flower structure), pappus of feathered hairs on their achenes. The other genera have a pappus of simple unbranched hairs. They are mostly native to Eurasia and northern Africa, with about 60 species from North America (although several species have been introduced outside their native ranges). The type (biology), lectotype species of the genus is ''Cirsium heterophyllum'' (L.) Hill. ''Cirsium'' thistles are known for their effusive flower heads, usually purple, rose or pink, also yellow or white. The radially symmetrical disc flowers are at the end of the branches and are visited by many kinds of insects, featuring a generalised pollination syndrome. Th ...

Endemic Flora Of Ethiopia
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomi ...

Cardueae
The Cardueae are a tribe (biology), tribe of flowering plants in the daisy family (Asteraceae) and the subfamily Carduoideae. Most of them are commonly known as thistles; four of the best known genera are ''Carduus'', ''Cynara'' (containing the widely eaten artichoke), ''Cirsium'', and ''Onopordum''. They are annual plant, annual, biennial plant, biennial, or perennial plant, perennial Herbaceous plant, herbs. Many species are thorn (botany), thorny on leaves, stems, or Involucral bract, involucre, and some have latex, laticifers or resin conduits. Almost 80 genera comprising 2500 species are assigned to this tribe, native of temperate regions of Europe and Asia (especially the Mediterranean region and Minor Asia), Australia and tropical Africa; only three genera contain species native to the Americas.Bremer 1994 ''Asteraceae'': Cladistic and Classification [Tribe ''Carduae'': 112-156] Taxonomy The correct name for the tribe has been disputed.

Cynara
''Cynara'' is a genus of thistle-like perennial plants in the family Asteraceae. They are native to the Mediterranean region, the Middle East, northwestern Africa, and the Canary Islands. The genus name comes from the Greek ''kynara'', which means "artichoke".''Cynara''. Flora of North America. Among the better known species in this genus include: * '' Cynara cardunculus'' is the cardoon, artichoke thistle, or wild artichoke.

Afrocirsium
''Afrocirsium'' is a genus of flowering plants in the sunflower family, Asteraceae. It includes three species of thistles native to the mountains of eastern tropical Africa. They are spiny perennial herbs growing 0.5 to 2.5 meters tall. They have the plumose pappus characteristic of genus ''Cirsium'', but have distinct characteristics like phyllaries with well-developed pectinate appendages which are not present in ''Cirsium'' and the other genera in the ''Carduus-Cirsium'' group.Moreyra, Lucía D., Núria Garcia-Jacas, Cristina Roquet, Jennifer R.

Pappus (botany)
In Asteraceae, the pappus is the modified calyx_(botany), calyx, the part of an individual floret, that surrounds the base of the petal, corolla tube in flower. It functions as a dispersal mechanism for the achenes that contain the seeds. In Asteraceae, the pappus may be composed of bristles (sometimes feathery), awns, scales, or may be absent, and in some species, is too small to see without magnification. In genera such as ''Taraxacum'' or ''Eupatorium'', feathery bristles of the pappus function as a "parachute" which enables the seed to be carried by the wind. In genera such as ''Bidens'' the pappus has hooks that function in mechanical dispersal. The name derives from the Ancient Greek word ''pappos'', Latin ''pappus'', meaning "old man", so used for a plant (assumed to be an ''Erigeron'' species) having bristles and also for the woolly, hairy seed of certain plants. The pappus of the Taraxacum, dandelion plays a vital role in the wind-aided dispersal of its seeds. By cr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Afromontane
The Afromontane regions are subregions of the Afrotropical realm, one of the Earth's eight biogeographic realms, covering the plant and animal species found in the mountains of Africa and the southern Arabian Peninsula. The Afromontane regions of Africa are discontinuous, separated from each other by lower-lying areas, and are sometimes referred to as the Afromontane archipelago, as their distribution is analogous to a series of sky islands. Geography Afromontane communities occur above elevation near the equator, and as low as elevation in the Knysna-Amatole montane forests of South Africa. Afromontane forests are generally cooler and more humid than the surrounding lowlands. The Afromontane archipelago mostly follows the East African Rift from the Red Sea to Zimbabwe, with the largest areas in the Ethiopian Highlands, the Albertine Rift Mountains of Uganda, Rwanda, Burundi, Democratic Republic of the Congo, and Tanzania, and the Eastern Arc highlands of Kenya and Tanzani ...

Ethiopian Highlands
The Ethiopian Highlands (also called the Abyssinian Highlands) is a rugged mass of mountains in Ethiopia in Northeast Africa. It forms the largest continuous area of its elevation in the continent, with little of its surface falling below , while the summits reach heights of up to . It is sometimes called the "Roof of Africa" due to its height and large area. It is the only country in the region with such a high elevated surface. This elevated surface is bisected diagonally by the Great East African Rift System which extends from Syria to Mozambique across the East African Lakes. Most of the Ethiopian Highlands are part of central and northern Ethiopia, and its northernmost portion reaches into Eritrean Highlands, Eritrea. History In the southern parts of the Ethiopian Highlands once was located the Kingdom of Kaffa, a medieval and Early modern period, early modern state, whence the coffee plant was exported to the Arabian Peninsula. The land of the former kingdom is mountainou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
