Agave Victoriae-reginae
''Agave victoriae-reginae'', the Queen Victoria agave or royal agave, is a small species of succulent flowering perennial plant, noted for its streaks of white on sculptured geometrical leaves, and popular as an ornamental. This agave is highly variable in form, but in general the rosettes are small and compact, growing to 0.5m, composed of short, rigid, thick leaves that are green with a pattern of distinctive white markings. The markings are generally along leaf keels or margins, giving a sort of polyhedral appearance. Marginal teeth are usually lacking, while the terminus of the leaf may include 1 to 3 spines, each 1.5–3 cm in length. Cream coloured flowers are borne in erect racemes up to 4m in length. ''A. victoriae-reginae'' is found in the Chihuahuan Desert in the Mexican States of Coahuila, Durango and Nuevo León, with about a half-dozen subspecies named. The situation is complicated by hybrids with a number of other agave species. Although it faces some local th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Moore (botanist)
Thomas Moore (21 May 1821 – 1 January 1887) was a British gardener and botanist. An expert on ferns and fern allies from the British Isles, he served as Curator of the Society of Apothecaries Garden from 1848 to 1887. In 1855, Moore authored ''The Ferns of Great Britain and Ireland.'' Life He was born at Stoke next Guildford, Stoke, near Guildford, Surrey, on 21 May 1821. He was brought up as a gardener, and was employed at Fraser's Lee Bridge Nursery, and subsequently, under Robert Marnock, in the laying out of the Regent's Park gardens. In 1848, by the influence of Dr. John Lindley, he was appointed curator of the Apothecaries' Company's Garden at Chelsea, in succession to Robert Fortune, an appointment which gave him leisure for other work. Under Moore's tenure during the period of so-called "pteridomania", the garden increased the number of fern species cultivated there by fifty percent and was renamed the Chelsea Physic Garden in 1875. The Thomas Moore Fernery was built i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and Data analysis, analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through buildin ...

Flora Of Nuevo León
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) was ...

Endemic Flora Of Mexico
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 ...

Agave
''Agave'' (; ; ) is a genus of monocots native to the arid regions of the Americas. The genus is primarily known for its succulent and xerophytic species that typically form large Rosette (botany), rosettes of strong, fleshy leaves. Many plants in this genus may be considered perennial, because they require several to many years to mature and flower. However, most ''Agave'' species are more accurately described as monocarpic rosettes or multiannuals, since each individual rosette semelparity, flowers only once and then dies; a small number of ''Agave'' species are polycarpic. Along with plants from the closely related genera ''Yucca'', ''Hesperoyucca'', and ''Hesperaloe,'' various ''Agave'' species are popular ornamental plants in hot, dry climates, as they require very little supplemental water to survive. Most ''Agave'' species grow very slowly. Some ''Agave'' species are known by the common name "century plant". is a Spanish word that refers to all of the large-leafed pla ...

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 ...
