Plicosepalus Sagittifolius
''Plicosepalus sagittifolius'' is a woody, photosynthesising, parasitic plant species that grows on the branches of mostly ''Acacia''-species, by means of tapping roots. It has glaucus, leathery, entire, 1–6 cm long leaves set oppositely along the stem, with umbels of initially long up-curved pale greenish-yellow buds, that open explosively, the petals usually bright yellow, strongly curling, long stamens and style clear red, orange or pink, and quickly falling after fertilisation. The initially green oval berries color red when ripe. The species is assigned to the showy mistletoe family. In the Afar language it is called hatote, while the vernacular name in the Oromo language is dertu dedacha. Description ''Plicosepalus sagittifolius'' is a small hemiparasitic shrub of around 1 m in diameter, that grows on the branches of different ''Acacia''-species, sometimes on ''Albizia'' and ''Commiphora''. It has eighteen chromosomes (2n=18). The species is closely rel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Pedicel (botany)
In botany, a pedicel is a stem that attaches a single flower to the inflorescence. Such inflorescences are described as ''pedicellate''. Description Pedicel refers to a structure connecting a single flower to its inflorescence. In the absence of a pedicel, the flowers are described as sessile. Pedicel is also applied to the stem of the infructescence. The word "pedicel" is derived from the Latin ''pediculus'', meaning "little foot". The stem or branch from the main stem of the inflorescence that holds a group of pedicels is called a peduncle. A pedicel may be associated with a bract or bracts. In cultivation In Halloween types of pumpkin or squash plants, the shape of the pedicel has received particular attention because plant breeders are trying to optimize the size and shape of the pedicel for the best "lid" for a "jack-o'-lantern".

Flora Of Ethiopia
The richness and variety of the wildlife of Ethiopia is dictated by the great diversity of terrain with wide variations in climate, soils, natural vegetation and settlement patterns. Ethiopia contains a vast highland complex of mountains and dissected plateaus divided by the Great Rift Valley, which runs generally southwest to northeast and is surrounded by lowlands, steppes, or semi-desert. Ethiopia is an ecologically diverse country, ranging from the deserts along the eastern border to the tropical forests in the south to extensive Afromontane in the northern and southwestern parts. Lake Tana in the north is the source of the Blue Nile. It also has many endemic species, including 31 mammal species, notably the gelada, the walia ibex and the Ethiopian wolf ("Simien fox"). There are seven mammal species classified as "critically endangered", and others as "endangered" or "vulnerable". The wide range of altitude has given the country a variety of ecologically distinct areas, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1895
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 ...

Commiphora
The genus of the myrrhs, ''Commiphora'', is the most species-rich genus of flowering plants in the frankincense and myrrh family, Burseraceae. The genus contains approximately 190 species of shrubs and trees, which are distributed throughout the (sub-) tropical regions of Africa, the western Indian Ocean islands, the Arabian Peninsula, India, and South America.Weeks, A. and Simpson, B.B. 2007. Molecular phylogenetic analysis of Commiphora (Burseraceae) yields insight on the evolution and historical biogeography of an “impossible” genus. Molecular Phylogenetics and Evolution. 42:62–79. The genus is drought-tolerant and common throughout the xerophytic scrub, seasonally dry tropical forests, and woodlands of these regions. The common name myrrh refers to several species of the genus, from which aromatic resins are derived for various fragrance and medicinal uses by humans. Description Leaves in ''Commiphora'' are pinnately compound (or very rarely unifoliolate). Many spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albizia
''Albizia'' is a genus of more than 160 species of mostly fast-growing subtropical and tropical trees and shrubs in the subfamily Mimosoideae of the family Fabaceae. The genus is pantropical, occurring in Asia, Africa, Madagascar, America and Australia, but mostly in the Old World tropics. In some locations, some species are considered weeds. They are commonly called silk plants, silk trees, or sirises. The obsolete spelling of the generic name – with double 'z' – is still common, so the plants may be called albizzias. The generic name honors the Italian nobleman Filippo degli Albizzi, who introduced ''Albizia julibrissin'' to Europe in the mid-18th century. Some species are commonly called mimosa, which more accurately refers to plants of genus ''Mimosa''. Species from southeast Asia used for timber are sometime termed East Indian walnut. Description They are usually small trees or shrubs with a short lifespan, though the famous ''Samán del Guère'' near Maracay in Venez ...

Acacia Mellifera
''Senegalia mellifera'' is a common thorn tree in Africa. The name ''mellifera'' refers to its sweet-smelling blossoms and honey. Its lumber turns pitch black when oiled. Common names of the tree include Blackthorn and Swarthaak (Afrikaans). It is listed as being not threatened. Distribution ''Senegalia mellifera'' is found in the dry areas of Africa and the Arabian Peninsula. Characteristics ''Senegalia mellifera'' can occur either as a multi-trunked bush up to seven metres high with more or less a funnel-shaped crown, or as a single-trunked tree that can reach a height of up to nine metres. It can form an impenetrable thickets. In some areas of Africa, it is considered an invasive species as it can expand into and cover large areas of farmland. Uses In Africa, ''Senegalia mellifera'' is used as fencing, livestock feed and building material for huts. It flowers are sources of nectar for honey-producing bees. The wood is prized also for fuel and making charcoal.Trees o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transvaal Province
The Province of the Transvaal ( af, Provinsie van Transvaal), commonly referred to as the Transvaal (; ), was a province of South Africa from 1910 until 1994, when a new constitution subdivided it following the end of apartheid. The name "Transvaal" refers to the province's geographical location to the north of the Vaal River. Its capital was Pretoria, which was also the country's executive capital. History In 1910, four British colonies united to form the Union of South Africa. The Transvaal Colony, which had been formed out of the bulk of the old South African Republic after the Second Boer War, became the Transvaal Province in the new union. Half a century later, in 1961, the union ceased to be part of the Commonwealth of Nations and became the Republic of South Africa. The PWV (Pretoria-Witwatersrand-Vereeniging) conurbation in the Transvaal, centred on Pretoria and Johannesburg, became South Africa's economic powerhouse, a position it still holds today as Gauteng Province ...

Epithet
An epithet (, ), also byname, is a descriptive term (word or phrase) known for accompanying or occurring in place of a name and having entered common usage. It has various shades of meaning when applied to seemingly real or fictitious people, divinities, objects, and binomial nomenclature. It can also be a descriptive title: for example, Pallas Athena, Phoebus Apollo, Alfred the Great, Suleiman the Magnificent, and Władysław I the Elbow-high. Many English monarchs have traditional epithets: some of the best known are Edward the Confessor, William the Conqueror, Richard the Lionheart, Æthelred the Unready, John Lackland and Bloody Mary. The word ''epithet'' can also refer to an abusive, defamatory, or derogatory phrase. This use as a euphemism is criticized by Martin Manser and other proponents of linguistic prescription. H. W. Fowler complained that "epithet is suffering a vulgarization that is giving it an abusive imputation." Linguistics Epithets are sometimes at ...

Combinatio Nova
''Combinatio nova'', abbreviated ''comb. nov.'' (sometimes ''n. comb.''), is Latin for "new combination". It is used in taxonomic biology literature when a new name is introduced based on a pre-existing name. The term should not to be confused with ', used for a previously unnamed species. There are three situations: * the taxon is moved to a different genus * an infraspecific taxon is moved to a different species * the rank of the taxon is changed. Examples When an earlier named species is assigned to a different genus, the new genus name is combined with of said species, e.g. when ''Calymmatobacterium granulomatis'' was renamed ''Klebsiella granulomatis'', it was referred to as ''Klebsiella granulomatis comb. nov.'' to denote it was a new combination.
