Flowering Plants Of South Africa
''Flowering Plants of Africa'' is a series of illustrated botanical magazines akin to ''Curtis's Botanical Magazine'', initiated as ''Flowering Plants of South Africa'' by I. B. Pole-Evans in 1920. It is now published by the South African National Biodiversity Institute in Pretoria. The magazine depicts and describes flowering plants from Africa and its neighbouring islands. The issues are printed in soft cover measuring 250 x 190 mm. The first volumes were printed in England by Lovell Augustus Reeve, L. Reeve & Co. These first illustrations were done in black and white by lithography, zinc plates later replacing the stone. A copy of the original water colour guided teams of hand-colour artists who applied paint where needed. Hand-colouring was a family craft carried on from generation to generation. Single colour printing was occasionally done to help speed the process, especially when skilled hand-colour artists were in short supply, as happened in World War II. Notable ...

Flowering Plants Of Africa01
A flower, sometimes known as a bloom or blossom, is the reproduction, reproductive structure found in flowering plants (plants of the division Angiospermae). The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) resulting from cross-pollination or allow selfing (fusion of sperm and egg from the same flower) when self-pollination occurs. There are two types of pollination: self-pollination and cross-pollination. Self-pollination occurs when the pollen from the anther is deposited on the Stigma (botany), stigma of the same flower, or another flower on the same plant. Cross-pollination is when pollen is transferred from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination happens in flowers where the stamen and carpel mature at the sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rosemary Holcroft
''Salvia rosmarinus'' (), commonly known as rosemary, is a shrub with fragrant, evergreen, needle-like leaves and white, pink, purple, or blue flowers, native to the Mediterranean region. Until 2017, it was known by the scientific name ''Rosmarinus officinalis'' (), now a synonym. It is a member of the sage family Lamiaceae, which includes many other medicinal and culinary herbs. The name "rosemary" derives from Latin ("dew of the sea"). Rosemary has a fibrous root system. Description Rosemary is an aromatic evergreen shrub with leaves similar to hemlock needles. It is native to the Mediterranean and Asia, but is reasonably hardy in cool climates. Special cultivars like 'Arp' can withstand winter temperatures down to about . It can withstand droughts, surviving a severe lack of water for lengthy periods. In some parts of the world, it is considered a potentially invasive species. The seeds are often difficult to start, with a low germination rate and relatively slow grow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mass Media In Pretoria
Mass is an intrinsic property of a body. It was traditionally believed to be related to the quantity of matter in a physical body, until the discovery of the atom and particle physics. It was found that different atoms and different elementary particles, theoretically with the same amount of matter, have nonetheless different masses. Mass in modern physics has multiple definitions which are conceptually distinct, but physically equivalent. Mass can be experimentally defined as a measure of the body's inertia, meaning the resistance to acceleration (change of velocity) when a net force is applied. The object's mass also determines the strength of its gravitational attraction to other bodies. The SI base unit of mass is the kilogram (kg). In physics, mass is not the same as weight, even though mass is often determined by measuring the object's weight using a spring scale, rather than balance scale comparing it directly with known masses.

Magazines Established In 1920
A magazine is a periodical publication, generally published on a regular schedule (often weekly or monthly), containing a variety of content. They are generally financed by advertising, purchase price, prepaid subscriptions, or by a combination of the three. Definition In the technical sense a '' journal'' has continuous pagination throughout a volume. Thus ''Business Week'', which starts each issue anew with page one, is a magazine, but the '' Journal of Business Communication'', which continues the same sequence of pagination throughout the coterminous year, is a journal. Some professional or trade publications are also peer-reviewed, for example the '' Journal of Accountancy''. Non-peer-reviewed academic or professional publications are generally ''professional magazines''. That a publication calls itself a ''journal'' does not make it a journal in the technical sense; ''The Wall Street Journal'' is actually a newspaper. Etymology The word "magazine" derives from Arabic , t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horticultural Magazines
Horticulture is the branch of agriculture that deals with the art, science, technology, and business of plant cultivation. It includes the cultivation of fruits, vegetables, nuts, seeds, herbs, sprouts, mushrooms, algae, flowers, seaweeds and non-food crops such as grass and ornamental trees and plants. It also includes plant conservation, landscape restoration, landscape and garden design, construction, and maintenance, and arboriculture, ornamental trees and lawns. The study and practice of horticulture have been traced back thousands of years. Horticulture contributed to the transition from nomadic human communities to sedentary, or semi-sedentary, horticultural communities.von Hagen, V.W. (1957) The Ancient Sun Kingdoms Of The Americas. Ohio: The World Publishing Company Horticulture is divided into several categories which focus on the cultivation and processing of different types of plants and food items for specific purposes. In order to conserve the science of horticultur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Botany Journals
Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (''botanē'') meaning "pasture", "herbs" "Poaceae, grass", or "fodder"; is in turn derived from (), "to feed" or "to Grazing, graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of Embryophyte, land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – and late ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cythna Letty
Cythna Lindenberg Letty (1 January 1895, in Standerton – 3 May 1985, in Pretoria), was a South African botanical artist and is regarded as a doyenne of South African botanical art by virtue of the quality and quantity of her meticulously executed paintings and pencil sketches, produced over a period of 40 years with the National Herbarium in Pretoria. Cythna Letty is best remembered for her book ''Wild Flowers of the Transvaal'' which was published in 1962. When decimal currency was introduced in South Africa, she was asked to design the floral motifs for the 10, 20 and 50 cent coins. Besides painting she was an accomplished poet and published ''Children of the Hours'' when she was in her eighties. Cythna was the eldest child of her mother Josina Christina Lindenberg's second marriage and was named after the heroine in Percy Shelley's poem "The Revolt of Islam".
