Christo Albertyn Smith
Christo Albertyn Smith (1898–1956) was a South African botanist. He co-wrote a definitive dictionary of common names of South African plants, although it was only published after his death. Education and career Smith was born in Boksburg, South Africa in 1898. He completed his BSc in 1920 at the University of Stellenbosch after which he worked as a high school biology teacher (1921 - 1924). He joined the professional staff of the Division of Plant Science of the National Herbarium in Pretoria in 1925 and became Botanical Liaison officer at the Kew Herbarium in London from 1928 - 1931. During his career he collected 4600 samples of flora including Crassulaceae, Fabaceae, Amaranthaceae, Vitaceae, Asteraceae, Celastraceae, Scrophulariaceae, Brassicaceae, Scilloideae, Oleaceae, Geraniaceae, Poaceae, Portulacaceae and Rutaceae, most of which were stored in Pretoria and Kew. He retired from academia in 1931 and entered journalism. He worked as agricultural editor for the Natal Wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boksburg
Boksburg is a city on the East Rand of Gauteng province of South Africa. Gold was discovered in Boksburg in 1887. Boksburg was named after the State Secretary of the South African Republic, W. Eduard Bok. The Main Reef Road linked Boksburg to all the other major mining towns on the Witwatersrand and the Angelo Hotel (1887) was used as a staging post. Boksburg is part of the City of Ekurhuleni Metropolitan Municipality, that forms the local government of most of the East Rand. The Mining Commissioner Montague White built a large dam which, empty for years, was dubbed White's Folly until a flash flood in 1889 silenced detractors. The 150,000 square metre dam is now the Boksburg Lake, and is surrounded by lawns, trees, and terraces. History Prior to 1860, the present municipal area of Boksburg and its immediate environs comprised mainly the highveld farms called Leeuwpoort, Klippoortje, Klipfontein and Driefontein. Carl Ziervogel bought the farm Leeuwpoort in 1875 and for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Celastraceae
The Celastraceae (staff-vine or bittersweet) are a family of 97 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 spindles) and ''Maytenus'' widespread in temperate climates, and ''Parnassia'' (bog-stars) found in alpine and arctic climates. Of the 97 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. Genera A complete list of the genera is: * ''Acanthothamnus'' * ''Allocassine'' * '' Anthodon'' * '' Apatophyllum'' * ''Apodostigma'' * ''Arnicratea'' * ''Bequaertia'' * '' Brassiantha'' * ''Brexia'' * '' Brexiella'' * '' Campylostemon'' * '' Canotia'' – crucifixion thorn * ...

Botanists With Author Abbreviations
This is a list of botanists who have Wikipedia articles, in alphabetical order by surname. The List of botanists by author abbreviation is mostly a list of plant taxonomists because an author receives a standard abbreviation only when that author originates a new plant name. Botany is one of the few sciences which can boast, since the Middle Ages, of a substantial participation by women.

JSTOR
JSTOR (; short for ''Journal Storage'') is a digital library founded in 1995 in New York City. Originally containing digitized back issues of academic journals, it now encompasses books and other primary sources as well as current issues of journals in the humanities and social sciences. It provides full-text searches of almost 2,000 journals. , more than 8,000 institutions in more than 160 countries had access to JSTOR. Most access is by subscription but some of the site is public domain, and open access content is available free of charge. JSTOR's revenue was $86 million in 2015. History William G. Bowen, president of Princeton University from 1972 to 1988, founded JSTOR in 1994. JSTOR was originally conceived as a solution to one of the problems faced by libraries, especially research and university libraries, due to the increasing number of academic journals in existence. Most libraries found it prohibitively expensive in terms of cost and space to maintain a comprehen ... [...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 ...

Portulacaceae
The Portulacaceae are a family of flowering plants, comprising 115 species in a single genus ''Portulaca''. Formerly some 20 genera with about 500 species, were placed there, but it is now restricted to encompass only one genus, the other genera being placed elsewhere. The family has been recognised by most taxonomists, and is also known as the purslane family. It has a cosmopolitan distribution, with the highest diversity in semiarid regions of the Southern Hemisphere in Africa, Australia, and South America, but with a few species also extending north into Arctic regions. The family is very similar to the Caryophyllaceae, differing in the calyx, which has only two sepals. The APG II system (2003; unchanged from the APG system of 1998) assigns it to the order Caryophyllales in the clade core eudicots. In the APG III system, several genera were moved to the Montiaceae, Didiereaceae, Anacampserotaceae and Talinaceae, thus making the family monotypic and only containing the genus ' ...

Poaceae
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, ...

Geraniaceae
Geraniaceae is a family of flowering plants placed in the order Geraniales. The family name is derived from the genus ''Geranium''. The family includes both the genus ''Geranium'' (the cranesbills, or true geraniums) and the garden plants called geraniums, which modern botany classifies as genus ''Pelargonium'', along with other related genera. The family comprises 830 species in five to seven genera. The largest genera are ''Geranium'' (430 species), ''Pelargonium'' (280 species) and ''Erodium'' (80 species). Description Geraniaceae are herbs or subshrubs. The ''Sarcocaulon'' are succulent, but other members of the family generally are not. Leaves are usually lobed or otherwise divided, sometimes peltate, opposite or alternate and usually have stipules. The flowers are generally regular, or symmetrical. They are hermaphroditic, actinomorphic (radially symmetrical, like in ''Geranium'') or slightly zygomorphic (with a bilateral symmetry, like in ''Pelargonium''). The calyx a ...

Oleaceae
Oleaceae, also known as the olive family, is a taxonomic family of flowering shrubs, trees, and a few lianas in the order Lamiales, It presently comprises 28 genera, one of which is recently extinct.Peter S. Green. 2004. "Oleaceae". pages 296-306. In: Klaus Kubitzki (editor) and Joachim W. Kadereit (volume editor). ''The Families and Genera of Vascular Plants'' volume VII. Springer-Verlag: Berlin; Heidelberg, Germany. The extant genera include ''Cartrema'', which was resurrected in 2012. The number of species in the Oleaceae is variously estimated in a wide range around 700. The flowers are often numerous and highly odoriferous.Vernon H. Heywood, Richard K. Brummitt, Ole Seberg, and Alastair Culham. ''Flowering Plant Families of the World''. Firefly Books: Ontario, Canada. . The family has a subcosmopolitan distribution, ranging from the subarctic to the southernmost parts of Africa, Australia, and South America.
