Cenchrus Alopecuroides
''Cenchrus alopecuroides'', previously ''Pennisetum alopecuroides'' (Pen-ih-SEE-tum al-oh-pek-yur-OY-deez), commonly known as the Chinese pennisetum, Chinese fountaingrass, dwarf fountain grass, foxtail fountain grass, or swamp foxtail grass, is a species of perennial grass native to Asia and Australia. The culms are erect, and 60–100 cm long. The leaf-blades are erect or drooping; flat, or conduplicate (folded lengthwise) or involute (spiral); and from 10 to 45 cm long by 3–6 mm wide. The Latin specific epithet ''alopecuroides'' means "like the genus ''Alopecurus'' (foxtail)". Description The plant is a warm season ornamental grass which typically grows in graceful, spreading clumps from tall and wide. It features narrow, medium to deep green leaves (to 1/2" wide) in summer, changing to golden yellow in fall, and fading to beige in late fall. The foliage usually remains attractive throughout the winter. Showy, silvery to pinkish-white, bristly, bottle brus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Specific Epithet
In Taxonomy (biology), 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 grammar, 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 (biology), 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1753
Plants are the eukaryotes that form the kingdom Plantae; they are predominantly photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants ( hornworts, liverworts, mosses, lycophytes, ferns, conifers and o ...

Cenchrus
''Cenchrus'' is a widespread genus of plants in the grass family, native to tropical and warm temperate regions of the world. Its species are native to many countries in Asia, Africa, Australia, the Americas, and various oceanic islands. Common names include buffelgrasses, sandburs, and sand spur. Such names allude to the sharp, spine-covered burrs characterizing the inflorescences of the members of the genus. Those previously classified as ''Pennisetum'' are known commonly as fountaingrasses (fountain grasses).''Pennisetum''. Integrated Taxonomic Information System (ITIS).''Pennisetum''.

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 ...

Cultivar
A cultivar is a kind of Horticulture, cultivated plant that people have selected for desired phenotypic trait, traits and which retains those traits when Plant propagation, propagated. Methods used to propagate cultivars include division, root and stem cuttings, offsets, grafting, micropropagation, tissue culture, or carefully controlled seed production. Most cultivars arise from deliberate human genetic engineering, 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, 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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alopecurus
''Alopecurus'', or foxtail grass, is a common and widespread genus of plants in the grass family. It is common across temperate and subtropical parts of Eurasia, northern Africa, and the Americas, as well as naturalized in Australia and on various islands. Foxtails can be annual or perennial. They grow in tufts. They have flat leaves and blunt ligules (a small flap at the junction of leaf and stem). Their inflorescence is a dense panicle (a branching head without terminal flower) with 1-flowered spikelets. A few, particularly ''A. myosuroides'', are considered weeds, others are very decorative and are used in bouquets of dried flowers. Species 43 species are accepted. * ''Alopecurus aequalis'' – Orange foxtail, shortawn foxtail – Eurasia, Americas * '' Alopecurus albovii'' – Caucasus * '' Alopecurus alopecuroides'' – Syria and Israel * '' Alopecurus anatolicus'' – eastern Turkey * ''Alopecurus apiatus'' – Kyrgyzstan, Tajikistan, Afghanistan, Iraq, Iran * ''A ...

Involute
In mathematics, an involute (also known as an evolvent) is a particular type of curve that is dependent on another shape or curve. An involute of a curve is the Locus (mathematics), locus of a point on a piece of taut string as the string is either unwrapped from or wrapped around the curve. The evolute of an involute is the original curve. It is generalized by the Roulette (curve), roulette family of curves. That is, the involutes of a curve are the roulettes of the curve generated by a straight line. The notions of the involute and evolute of a curve were introduced by Christiaan Huygens in his work titled ''Horologium Oscillatorium, Horologium oscillatorium sive de motu pendulorum ad horologia aptato demonstrationes geometricae'' (1673), where he showed that the involute of a cycloid is still a cycloid, thus providing a method for constructing the cycloidal pendulum, which has the useful property that its period is independent of the amplitude of oscillation. Involute of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conduplicate
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] |
Culm (botany)
A culm is the aerial (above-ground) Plant stem, stem of a Poaceae, grass or Cyperaceae, sedge. It is derived from Latin , meaning "stalk." It originally referred to the stem of any type of plant. In horticulture or agriculture, it is especially used to describe the stalk or woody stems of bamboo, cane (grass), cane or cereal, grain grasses. Malting In the production of malted grains, the culms refer to the rootlets of the germinated grains. The culms are normally removed in a process known as "deculming" after kilning when producing barley malt, but form an important part of the product when making sorghum or millet malt. These culms are very nutritious and are sold off as animal feed. References Plant morphology {{Plant-morphology-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
