Frithia Pulchra
''Frithia pulchra'', the fairy elephant's feet, is a species of flowering plant in the figmarigold family Aizoaceae, endemic to Gauteng Province, South Africa (where it is classified as "Vulnerable" by the IUCN Red List). Its natural habitat is temperate grassland with high summer rainfall. A tiny stemless succulent growing to just tall and broad, it has bulbous oblong leaves with leaf windows at the tip; and magenta and white daisy-like flowers in summer. During periods of drought it has the ability to shrink beneath the soil surface, thus avoiding excessive desiccation, but making it extremely difficult to find. It is named for Frank Frith, a Johannesburg gardener who showed specimens to N.E. Brown, a botanist at Kew Gardens, while on a visit to London, UK, in 1925. The Latin specific epithet ''pulchra'' means "beautiful". It does not survive frosts, so in temperate areas it needs to be cultivated under glass. In the UK it has gained the Royal Horticultural Society's Award ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nicholas Edward Brown
Nicholas Edward Brown (11 July 1849 in Redhill, Surrey – 25 November 1934 in Kew Gardens, London) was an English plant taxonomist and authority on succulents. He was also an authority on several families of plants, including Asclepiadaceae, Aizoaceae, Labiatae and Cape plants. Background He started work as an assistant in the Herbarium at Kew in 1873, and was promoted to the position of Assistant Keeper in 1909, which he kept until 1914. He produced many annotated drawings of succulent plants in his work revising the genus '' Mesembryanthemum'', which were published in 1931. He was the author of several works on the taxonomy of plants, particularly succulents. The Araceae genus '' Nebrownia'' was named in his honour by Otto Kuntze. A number of plants bear the specific name "''nebrownii''" – such as ''Acacia nebrownii'', ''Gibbaeum nebrownii'', ''Caralluma nebrownii'' and ''Lithops olivacea v nebrownii'', as does a waterhole in the Etosha National Park. The plant '' Anthuri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (often shortened to just "binomial"), a binomen, name, or a scientific name; more informally, it is also called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called nomenclature, with an "n" before the "al" in "binominal", which is a typographic error, meaning "two-name naming system". The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Hom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aizoaceae
The Aizoaceae (), or fig-marigold family, is a large family of dicotyledonous flowering plants containing 135 genera and about 1,800 species. Several genera are commonly known as 'ice plants' or 'carpet weeds'. The Aizoaceae are also referred to as ''vygies'' in South Africa. Some of the unusual Southern African genera—such as '' Conophytum'', '' Lithops'', '' Titanopsis'' and '' Pleiospilos'' (among others)—resemble gemstones, rocks or pebbles, and are sometimes referred to as 'living stones' or 'mesembs' (short for mesembryanthemums). Description The family Aizoaceae is widely recognised by taxonomists. It once went by the botanical name "Ficoidaceae", now disallowed. The APG II system of 2003 (unchanged from the APG system of 1998) also recognizes the family, and assigns it to the order Caryophyllales in the clade core eudicots. The APG II system also classes the former families Mesembryanthemaceae Fenzl, Sesuviaceae Horan. and Tetragoniaceae Link under the family ...

Flora Of The Northern Provinces
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) wa ...

Endemic Flora Of South Africa
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 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 larger area or becomin ...

University Of California Botanical Garden
The University of California Botanical Garden is a 34-acre (13.7 ha) botanical garden located on the University of California, Berkeley campus, in Strawberry Canyon. The garden is in the Berkeley Hills, inside the city boundary of Oakland, with views overlooking the San Francisco Bay. It is one of the most diverse plant collections in the United States, and famous for its large number of rare and endangered species. History Development The garden is situated on the land of the Chochenyo speaking Ohlone people called xučyun (Huichin). In the 1870s, a few years after the founding of the University of California, Berkeley, Dr. Eugene W. Hilgard, the university's first Dean of Agriculture, established a garden of plants on the land which is now Moffit Library. The University of California Botanical Garden was initially established in 1890 near Haviland Hall on the north side of campus by E.L. Greene, the first chairman of the Department of Botany, to preserve the trees, shr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Award Of Garden Merit
The Award of Garden Merit (AGM) is a long-established award for plants by the British Royal Horticultural Society (RHS). It is based on assessment of the plants' performance under UK growing conditions. It includes the full range of cultivated plants, from annuals, biennials and perennials to shrubs and trees. It covers plants grown for specific purposes - such as vegetable crops, fruit, hedging, topiary, groundcover, summer bedding, houseplants, etc. It tests characteristics such as robustness, hardiness, longevity, flowering/fruiting abundance and quality, usefulness, and ease of cultivation. It pays particular attention to a plant's ability to survive and thrive in challenging conditions such as wind and frost. The AGM trophy symbol is widely used in gardening literature as a sign of exceptional quality, and is recognised as such by writers, horticulturalists, nurseries, and everybody in the UK who practises gardening.

Royal Horticultural Society
The Royal Horticultural Society (RHS), founded in 1804 as the Horticultural Society of London, is the UK's leading gardening charity. The RHS promotes horticulture through its five gardens at Wisley (Surrey), Hyde Hall (Essex), Harlow Carr (North Yorkshire), Rosemoor (Devon) and Bridgewater (Greater Manchester); flower shows including the Chelsea Flower Show, Hampton Court Palace Flower Show, Tatton Park Flower Show and Cardiff Flower Show; community gardening schemes; Britain in Bloom and a vast educational programme. It also supports training for professional and amateur gardeners. the president was Keith Weed and the director general was Clare Matterson CBE. History Founders The creation of a British horticultural society was suggested by John Wedgwood (son of Josiah Wedgwood) in 1800. His aims were fairly modest: he wanted to hold regular meetings, allowing the society's members the opportunity to present papers on their horticultural activities and discov ...

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaf Window
Leaf window, also known as epidermal window, and fenestration, is a specialized leaf structure consisting of a translucent area through which light can enter the interior surfaces of the leaf where photosynthesis can occur. The translucent structure may include epidermal tissue, and in some succulent plants it consists of several cell layers of parenchyma, which may also function as water-storage tissue. It can appear as a large continuous patch, a variegated or reticulated region, or as numerous small spots. It is found in some succulent plants native to arid climates, allowing much of the plant to remain beneath the soil surface where it is protected from desiccation by winds and heat while optimizing light absorption. Many species featuring leaf windows are native to Southern Africa. Functions The primary function of the translucent windows is to increase the absorption of radiant energy, and thereby the rate of photosynthesis. Epidermal windows are commonly situated at the ape ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
