Eucomis Vandermerwei
''Eucomis vandermerwei'' is a South African bulbous perennial flowering plant, a member of the asparagus family (Asparagaceae, subfamily Scilloideae), and like other members of '' Eucomis'' is commonly known as pineapple lily for its superficial resemblance to that plant ('' Ananas comosus''), although not closely related to it. This species is one of the smallest in the genus, and is native to a high-rainfall region of western Mpumalanga in South Africa. The dense rosette of leaves, either prostrate or ascending, is heavily blotched with purple, and the leaf-edges are markedly crisped or wavy. The star-shaped burgundy flowers appear in midsummer (November–January in South Africa), and are borne on a spike (raceme) topped by a "head" of leafy bracts. Description ''Eucomis vandermerwei'' is a short summer-growing bulbous plant, reaching at most tall. It bulb is ovoid, across. Three to six leaves emerge from a bulb and are up to long and wide, heavily spotted and marked wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inez Clare Verdoorn
Inez Clare Verdoorn (15 June 1896 – 2 April 1989) was a South African botanist and taxonomist, noted for her major revisions of plant families and genera. She is also a niece of Eugene Nielen Marais, lawyer, naturalist, poet and writer. She matriculated in 1916 from Loreto Convent School in Pretoria, worked for a while in the office of the Controller and Auditor General before being appointed in 1917 as a herbarium assistant at the Division of Botany and Plant Pathology. Between 1925 and 1927 she worked at Kew as liaison officer for the National Herbarium. On her return to Pretoria, she assumed charge of the herbarium and was promoted to Senior Professional Officer in 1944. Despite having arrived at retirement age in 1951, Verdoorn opted to work on as a temporary staff member until 1968, and thereafter as an unpaid research worker. She has more than 200 botanical publications to her credit, including major revisions, appearing mainly in ''Bothalia'', ''Flowering Plants of ...

World Checklist Of Selected Plant Families
The World Checklist of Selected Plant Families (usually abbreviated to WCSP) is an "international collaborative programme that provides the latest peer reviewed and published opinions on the accepted scientific names and synonyms of selected plant families." Maintained by the Royal Botanic Gardens, Kew, it is available online, allowing searches for the names of families, genera and species, as well as the ability to create checklists. The project traces its history to work done in the 1990s by Kew researcher Rafaël Govaerts on a checklist of the genus '' Quercus''. Influenced by the Global Strategy for Plant Conservation, the project expanded. , 173 families of seed plants were included. Coverage of monocotyledon families is complete; other families are being added. There is a complementary project called the International Plant Names Index (IPNI), in which Kew is also involved. The IPNI aims to provide details of publication and does not aim to determine which are accep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cultivar
A cultivar is a type of cultivated plant that people have selected for desired traits and when propagated retain those traits. Methods used to propagate cultivars include: division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production. Most cultivars arise from purposeful human manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in '' Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants that share the unique characteristics that define the cultivar. was coined as a term meaning "cultivated vari ...

Award Of Garden Merit
The Award of Garden Merit (AGM) is a long-established annual award for plants by the British Royal Horticultural Society (RHS). It is based on assessment of the plants' performance under UK growing conditions. History The Award of Garden Merit is a mark of quality awarded, since 1922, to garden plants (including trees, vegetables and decorative plants) by the United Kingdom, Royal Horticultural Society (RHS). Awards are made annually after plant trials intended to judge the plants' performance under UK growing conditions. Trials may last for one or more years, depending on the type of plant being analyzed, and may be performed at Royal Horticulture Society Garden in Wisley and other gardens or after observation of plants in specialist collections. Trial reports are made available as booklets and on the website. Awards are reviewed annually in case plants have become unavailable horticulturally, or have been superseded by better cultivars. Similar awards The award should not b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Sue Biggs 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 discoveries, to ...

Offset (botany)
In botany and horticulture, an offset (also called a pup) is a small, virtually complete daughter plant that has been naturally and asexually produced on the mother plant. They are clones, meaning that they are genetically identical to the mother plant. They divide mitotically. In the plant nursery business and gardens, they are detached and grown in order to produce new plants. This is a cheap and simple process for those plants that readily produce offsets as it does not usually require specialist materials and equipment. An offset or pup may also be used as a broad term to refer to any short shoot originating from the ground at the base of another shoot. Offsets form when meristem regions of plants, such as axillary buds or homologous structures, differentiate into a new plant with the ability to become self-sustaining. This is particularly common in species that develop underground storage organs, such as bulbs, corms and tubers. Tulips and lilies are examples of plants ...

Great Britain
Great Britain is an island in the North Atlantic Ocean off the northwest coast of continental Europe. With an area of , it is the largest of the British Isles, the largest European island and the ninth-largest island in the world. It is dominated by a maritime climate with narrow temperature differences between seasons. The 60% smaller island of Ireland is to the west—these islands, along with over 1,000 smaller surrounding islands and named substantial rocks, form the British Isles archipelago. Connected to mainland Europe until 9,000 years ago by a landbridge now known as Doggerland, Great Britain has been inhabited by modern humans for around 30,000 years. In 2011, it had a population of about , making it the world's third-most-populous island after Java in Indonesia and Honshu in Japan. The term "Great Britain" is often used to refer to England, Scotland and Wales, including their component adjoining islands. Great Britain and Northern Ireland now const ...

Crypsis
In ecology, crypsis is the ability of an animal or a plant to avoid observation or detection by other animals. It may be a predation strategy or an antipredator adaptation. Methods include camouflage, nocturnality, subterranean lifestyle and mimicry. Crypsis can involve visual, olfactory (with pheromones) or auditory concealment. When it is visual, the term cryptic coloration, effectively a synonym for animal camouflage, is sometimes used, but many different methods of camouflage are employed by animals or plants. Overview There is a strong evolutionary pressure for animals to blend into their environment or conceal their shape, for prey animals to avoid predators and for predators to be able to avoid detection by prey. Exceptions include large herbivores without natural enemies, brilliantly colored birds that rely on flight to escape predators, and venomous or otherwise powerfully armed animals with warning coloration. Cryptic animals include the tawny frogmouth (feather pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornamental Bulbous Plant
Ornamental bulbous plants, often called ornamental bulbs or just bulbs in gardening and horticulture, are herbaceous perennials grown for ornamental purposes, which have underground or near ground storage organs. Botanists distinguish between true bulbs, corms, rhizomes, tubers and tuberous roots, any of which may be termed "bulbs" in horticulture. Bulb species usually lose their upper parts during adverse conditions such as summer drought and heat or winter cold. The bulb's storage organs contain moisture and nutrients that are used to survive these adverse conditions in a dormant state. When conditions become favourable the reserves sustain a new growth cycle. In addition, bulbs permit vegetative or asexual multiplication in these species. Ornamental bulbs are used in parks and gardens and as cut flowers. Terminology The word "bulb" has a somewhat different meaning to botanists than it does to gardeners and horticulturalists. In gardening, a "bulb" is a plant's undergro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
