Empleuridium , but a compreh ...
''Empleuridium'' is a genus of flowering plants belonging to the family Celastraceae, with a single species ''Empleuridium juniperinum''. Its native range is the Cape Provinces of South Africa. Taxonomy The genus and species were first named and the species described in ''Thesaurus Capensis'' published in 1859. This contained illustrations and brief descriptions of South African plants. A more systematic treatment of the genus and species appeared in ''Flora Capensis'', the relevant part of which is dated to 1860. The author of the genus is given as Otto Wilhelm Sonder and the authors of the species as Sonder and William H. Harvey. The genus was originally tentatively assigned to the family Rutaceae The Rutaceae () is a family (biology), family, commonly known as the rueRUTACEAE in Bo ...

Celastraceae
The Celastraceae (staff-vine or bittersweet) are a family of 98 genera and 1,350 species of herbs, vines, shrubs and small trees, belonging to the order Celastrales. The great majority of the genera are tropical, with only ''Celastrus'' (the staff vines), ''Euonymus'' (the spindle (shrub), spindles) and ''Maytenus'' widespread in temperate climates, and ''Parnassia'' (bog-stars) found in alpine and arctic climates. Of the 98 currently recognized genera of the family Celastraceae, 19 are native to Madagascar and these include at least 57 currently recognized species. Six of these 19 genera (''Brexiella'', ''Evonymopsis'', ''Hartogiopsis'', ''Polycardia'', ''Ptelidium'', and ''Salvadoropsis'') are endemic to Madagascar. These genera each have distinctive traits and functions of their own. Genera 98 genera are accepted by Plants of the World Online : * ''Acanthothamnus'' * ''Allocassine'' * ''Anthodon (plant), Anthodon'' * ''Apatophyllum'' * ''Apodostigma'' * ''Arnicratea'' ...

Otto Wilhelm Sonder
Otto Wilhelm Sonder (18 June 1812, Bad Oldesloe – 21 November 1881) was a German botanist and pharmacist. Life A native of Holstein, Sonder studied at Kiel University, where he sat pharmaceutical examinations in 1835, before becoming the proprietor of a pharmacy in Hamburg from 1841 to 1878. In 1846 he received an honorary doctorate from the University of Königsberg and was elected a member of the German National Academy of Sciences Leopoldina for his contribution to the field of botany. Herbarium From a young age, Sonder showed considerable interest and skill in Botany. He often embarked on botanical excursions in his local area early in the morning before heading to work at the pharmacy. Throughout his life, Sonder met and conversed with many eminent botanists of the era. He amassed an extensive botanical collection that contained hundreds of thousands of herbarium specimens representing all major plant groups and spanning all parts of the globe. The collection is partic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Henry Harvey
William Henry Harvey, FRS FLS (5 February 1811 – 15 May 1866) was an Irish botanist and phycologist who specialised in algae. Biography Harvey was born at Summerville near Limerick, Ireland, in 1811, the youngest of 11 children. His father Joseph Massey Harvey, was a Quaker and prominent merchant. William started his education at Ballitore School in County Kildare and by the age of 15 had already established algae as his over-riding interest.Papenfuss, G.F. 1976. pp.21–46. Landmarks in Pacific North American Marine Phycology. ''in'' Abbott, I.A. and Hollenberg, G.J. 1976. ''Marine Algae of California''. Stanford University Press, California. After leaving school he joined the family business. Harvey was an authority on algae and bryophytes (mosses), and author of ''A Manual of the British Algae'' (1841), ''Phycologia Britannica'' (4 vols., 1846–51), ''Nereis Boreali-Americana.'' (3 parts 1852–85) and '' Phycologia Australica'' (5 vol., 1858–63). He spent several ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of Embryophyte, land plants with 64 Order (biology), orders, 416 Family (biology), families, approximately 13,000 known Genus, genera and 300,000 known species. They include all forbs (flowering plants without a woody Plant stem, stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Provinces
The Cape Provinces of South Africa is a biogeographical area used in the World Geographical Scheme for Recording Plant Distributions (WGSRPD). It is part of the WGSRPD region 27 Southern Africa. The area has the code "CPP". It includes the South African provinces of the Eastern Cape, the Northern Cape and the Western Cape, together making up most of the former Cape Province. The area includes the Cape Floristic Region, the smallest of the six recognised floral kingdoms of the world, an area of extraordinarily high diversity and endemism 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 foun ..., home to more than 9,000 vascular plant species, of which 69 percent are endemic.

South Africa
South Africa, officially the Republic of South Africa (RSA), is the Southern Africa, southernmost country in Africa. Its Provinces of South Africa, nine provinces are bounded to the south by of coastline that stretches along the Atlantic Ocean, South Atlantic and Indian Ocean; to the north by the neighbouring countries of Namibia, Botswana, and Zimbabwe; to the east and northeast by Mozambique and Eswatini; and it encloses Lesotho. Covering an area of , the country has Demographics of South Africa, a population of over 64 million people. Pretoria is the administrative capital, while Cape Town, as the seat of Parliament of South Africa, Parliament, is the legislative capital, and Bloemfontein is regarded as the judicial capital.

Rutaceae
The Rutaceae () is a family (biology), family, commonly known as the rueRUTACEAE in BoDD – Botanical Dermatology Database or citrus family, of flowering plants, usually placed in the order (biology), order Sapindales. Species of the family generally have flowers that divide into four or five parts, usually with strong scents. They range in form and size from Herbaceous plant, herbs to shrubs and large trees. The most economically important genus in the family is ''Citrus'', which includes the Orange (fruit), orange (''C.'' × ''sinensis''), lemon (''C.'' × ''limon''), grapefruit (''C.'' × ''paradisi''), and Lime (fruit), lime (various).

Monotypic Celastrales Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical system. ...

Endemic Flora Of The Cape Provinces
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 (ecology), 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 la ...

Taxa Named By William Henry Harvey
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
