Limeum
''Limeum'' is a genus of flowering plants. It includes 25 species. ''Limeum'' has traditionally been recognized as belonging to the Molluginaceae family, but is now treated as the sole genus in the family Limeaceae. The family is newly recognized through research by the Angiosperm Phylogeny Group III system to deal with long-standing phylogenetic difficulties in placing various genera within the Caryophyllales. ''Limeum'' comprises subshrub and herbaceous species native to tropical, eastern and southern Africa, and South Asia. Previously, the genus ''Macarthuria'' from Australia was placed here, but it now is found to belong to Macarthuriaceae Macarthuriaceae is a family of plants in the order Caryophyllales and consists of a single genus, '' Macarthuria''. Description Macarthuriaceae are rigid or wiry, rush-like herbs or subshrubs with green stems and reduced leaves. The small flower ....

Molluginaceae
The Molluginaceae are a family of flowering plants recognized by several taxonomists. It was previously included in the larger family Aizoaceae. The APG III system of 2009 made no change in the status of the family as compared to the APG II system of 2003 and the APG system of 1998, apart from a reassignment of several genera, such as the placement of ''Corrigiola'' and '' Telephium'' into Caryophyllaceae, '' Corbichonia'' in Lophiocarpaceae, '' Microtea'' into Microteaceae and '' Limeum'' in Limeaceae, because the family was found to be widely polyphyletic in Caryophyllales. In addition ''Macarthuria'' was found not to be related to '' Limeum'' as previously thought and thus it was placed in Macarthuriaceae, and similarly species formerly placed in ''Hypertelis'', apart from type species ''Hypertelis spergulacea'', a true Molluginaceae, were found to belong elsewhere and were described as '' Kewa'' in the family Kewaceae, named for the Royal Botanic Gardens Kew.

Macarthuriaceae
Macarthuriaceae is a family of plants in the order Caryophyllales and consists of a single genus, ''Macarthuria''. Description Macarthuriaceae are rigid or wiry, rush-like herbs or subshrubs with green stems and reduced leaves. The small flowers have five perianth members, sometimes also five "petals", and eight stamens fused at the base. Taxonomy In 2009, ''Macarthuria'' was placed with ''Limeum'' in the Limeaceae, based on its morphology, but at that time no molecular material of ''Macarthuria'' had been examined. Prior to this, Endress and Bittrich had placed it in the family Molluginaceae. However, in 2011, molecular evidence was published, showing that ''Macarthuria'' is sister to all core Caryophyllales. Thus, ''Macarthuria ''Macarthuria'' is a genus of dicotyledonous plants belonging to the family Macarthuriaceae, and consists of about 9 species which are endemic to Australia.

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

APG III System
The APG III system of flowering plant classification is the third version of a modern, mostly molecular-based, system of plant taxonomy being developed by the Angiosperm Phylogeny Group (APG). Published in 2009, it was superseded in 2016 by a further revision, the APG IV system. Along with the publication outlining the new system, there were two accompanying publications in the same issue of the Botanical Journal of the Linnean Society: * The first, by Chase & Reveal, was a formal phylogenetic classification of all land plants (embryophytes), compatible with the APG III classification. As the APG have chosen to eschew ranks above order, this paper was meant to fit the system into the existing Linnaean hierarchy for those that prefer such a classification. The result was that all land plants were placed in the class Equisetopsida, which was then divided into 16 subclasses and a multitude of superorders. * The second, by Haston ''et al.'', was a linear sequence of families followi ...

Caryophyllales
Caryophyllales ( ) is a diverse and heterogeneous order of flowering plants that includes the cacti, carnations, amaranths, ice plants, beets, and many carnivorous plants. Many members are succulent, having fleshy stems or leaves. The betalain pigments are unique in plants of this order and occur in all its families with the exception of Caryophyllaceae and Molluginaceae. Description The members of Caryophyllales include about 6% of eudicot species. This order is part of the core eudicots. Currently, the Caryophyllales contains 37 families, 749 genera, and 11,620 species The monophyly of the Caryophyllales has been supported by DNA sequences, cytochrome c sequence data and heritable characters such as anther wall development and vessel-elements with simple perforations. Circumscription As with all taxa, the circumscription of Caryophyllales has changed within various classification systems. All systems recognize a core of families with centrospermous ovules and seeds. Mor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Asia
South Asia is the southern subregion of Asia, which is defined in both geographical and ethno-cultural terms. The region consists of the countries of Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka.;;;;;;;; Topographically, it is dominated by the Indian subcontinent and defined largely by the Indian Ocean on the south, and the Himalayas, Karakoram, and Pamir mountains on the north.
