Urceolina Amazonica
''Urceolina amazonica'', formerly known as ''Eucharis amazonica'', is a species of flowering plant in the family Amaryllidaceae, native to Peru. It is cultivated as an ornamental in many countries and naturalized in Venezuela, Mexico, the West Indies, Ascension Island, Sri Lanka, Fiji, the Solomon Islands and the Society Islands. The English name Amazon lily is used for this species, but is also used for some other species of the genus '' Urceolina''. Description An evergreen bulbous perennial, ''Urceolina amazonica'' grows to tall by broad, with long narrow dark leaves and umbels of fragrant white flowers with six tepals. The stamens are fused at their bases forming a staminal cup in the center of the perianth. The free parts of filaments are subulate and flat. It is a sterile aneutriploid (2n=3x−1=68). Taxonomy The species was introduced to Europe in the summer of 1855 by Marius Porte who discovered it on the banks of the Amazon River near Moyobamba, Peru. Jean Jules Lin ...

Curtis's Botanical Magazine
''The Botanical Magazine; or Flower-Garden Displayed'', is an illustrated publication which began in 1787. The longest running botanical magazine, it is widely referred to by the subsequent name ''Curtis's Botanical Magazine''. Each of the issues contains a description, in formal yet accessible language, and is renowned for featuring the work of two centuries of botanical illustrators. Many plants received their first publication on the pages, and the description given was enhanced by the keenly detailed illustrations. History and profile The first issue, published on 1 February 1787, was begun by William Curtis, as both an illustrated gardening and botanical journal. Curtis was an apothecary and botanist who held the position of Praefectus Horti (Director) and demonstrator of plants at the Chelsea Physic Garden, who had published the highly praised (but poorly sold) ''Flora Londinensis'' a few years before. The publication familiarized its readers with ornamental and exotic plan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subulate
The following terms are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (that is, the leaf blade or 'lamina' is undivided) or compound (that is, the leaf blade is divided into two or more leaflets). The edge of the leaf may be regular or irregular, and may be smooth or have hair, bristles, or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "acu ... [...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 ...

Hardiness (plants)
Hardiness of plants describes their ability to survive adverse growing conditions. It is usually limited to discussions of climatic adversity. Thus a plant's ability to tolerate cold, heat, drought, flooding, or wind are typically considered measurements of hardiness. Hardiness of plants is defined by their native extent's geographic location: longitude, latitude and elevation. These attributes are often simplified to a hardiness zone. In temperate latitudes, the term most often describes resistance to cold, or "cold-hardiness", and is generally measured by the lowest temperature a plant can withstand. Hardiness of a plant may be divided into two categories: tender, and hardy. Tender plants are those killed by freezing temperatures, while hardy plants survive freezing—at least down to certain temperatures, depending on the plant. "Half-hardy" is a term used sometimes in horticulture to describe bedding plants which are sown in heat in winter or early spring, and planted outsi ...

Phylogenetic Network
A phylogenetic network is any graph used to visualize evolutionary relationships (either abstractly or explicitly) between nucleotide sequences, genes, chromosomes, genomes, or species. They are employed when reticulation events such as hybridization, horizontal gene transfer, recombination, or gene duplication and loss are believed to be involved. They differ from phylogenetic trees by the explicit modeling of richly linked networks, by means of the addition of hybrid nodes (nodes with two parents) instead of only tree nodes (a hierarchy of nodes, each with only one parent). Phylogenetic trees are a subset of phylogenetic networks. Phylogenetic networks can be inferred and visualised with software such as SplitsTree, the R-package, phangorn, and, more recently, Dendroscope. A standard format for representing phylogenetic networks is a variant of Newick format which is extended to support networks as well as trees. Many kinds and subclasses of phylogenetic networks have bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clade
In biology, a clade (), also known as a Monophyly, monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of its descendants. Clades are the fundamental unit of cladistics, a modern approach to taxonomy adopted by most biological fields. The common ancestor may be an individual, a population, or a species (extinct or Extant taxon, extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed ''monophyletic'' (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming Taxon, taxa that are not clades; that is, taxa that are not Monophyly, monophyletic. Some of the relationships between organisms that the molecul ...

Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetics, phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in Taxonomy (biology), taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tre ...

Alan Meerow
Alan W. Meerow is an American botanist, born in New York City in 1952. He specializes in the taxonomy of the family Amaryllidaceae and the horticulture of palms and tropical ornamental plants. He also works on the population genetics and molecular systematics of cycads and palms. He studied at the Bronx High School of Science and then at the University of New York. Dropping out after a year, aged 19, he moved to Santa Cruz, California. After living on a farm for four years he decided to resume his studies in botany and horticulture at the University of California. Initially his interest in botany was focused on trees, working for three years in the arboretum of the University. He graduated in December 1978 and continued his postgraduate study at the University of Florida, after working for two years at the Marie Selby Botanical Gardens in Sarasota, Florida, where his interest in Amaryllidaceae was stimulated. His master's thesis, in 1983, was on the taxonomy of the genus '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nomen Nudum
In Taxonomy (biology), taxonomy, a ''nomen nudum'' ('naked name'; plural ''nomina nuda'') is a designation which looks exactly like a scientific name of an organism, and may have originally been intended to be one, but it has not been published with an adequate description. This makes it a "bare" or "naked" name, which cannot be accepted as it stands. A largely equivalent but much less frequently used term is ''nomen tantum'' ("name only"). Sometimes, "''nomina nuda''" is erroneously considered a synonym for the term "unavailable names". However, not all unavailable names are ''nomina nuda'' which applies to published names, ''i.e.'' any published name that does not fulfill the requirements of Article 12 (if published before 1931) or Article 13 (if published after 1930). In zoology According to the rules of zoological nomenclature a ''nomen nudum'' is unavailable name, unavailable; the glossary of the ''International Code of Zoological Nomenclature'' gives this definition: And ...

Veitch Nurseries
The Veitch Nurseries were the largest group of family-run plant nurseries in Europe during the 19th century. Started by John Veitch sometime before 1808, the original nursery grew substantially over several decades and was eventually split into two separate businesses—based at Chelsea and Exeter—as it became unfeasible to run the whole operation from one location. There was a Veitch Nursery in Kingston at Coombe, on Kingston Hill. Famous plant hunters in the Victorian period employed by the Veitch family include the brothers Thomas Lobb and William Lobb from Cornwall and David Bowman. The Veitch's ability to grow exotic plants is noted in William Jackson Hooker's description of '' Verticordia nitens'', and they were able to supply a specimen for its illustration. The firm had, by the outbreak of the First World War, introduced 1281 plants into cultivation, which were either previously unknown or newly-bred varieties (see cultivars). These included 498 greenhouse plant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
