Persicaria Affinis
''Bistorta affinis'' (synonyms ''Polygonum affine'', ''Persicaria affinis''), the Himalayan bistort, fleece flower, or knotweed, is a species of flowering plant in the family Polygonaceae, native to the Himalayas (Tibet, Nepal, northern India, Pakistan, Kashmir). Description ''Bistorta affinis'' is a creeping, densely tufted, mat-forming perennial, growing to tall by broad. The narrow elliptic leaves are white on the underside because of a waxy coating. Leaves are mostly at the base, 3–8 cm long, with the base narrowed to a short stalk. Leaf margins are entire or very finely toothed. The mid-vein is prominent. Cylindrical spikes of many pale pink or rose-red flowers are borne at the top of short erect stems, from midsummer to autumn. Flower-spikes are long, with densely crowded flowers. Stamens protrude slightly out of the flowers. Flowering stems are several, 5–25 cm tall, with very few smaller leaves. When the flowers have died, they tend to persist on the plant ...

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...

Bistorta
''Bistorta'' is a genus of flowering plants in the family Polygonaceae. about 40 species are accepted. It has been supported as a separate clade by molecular phylogenetic analysis. ''Bistorta'' species are native throughout much of the Northern Hemisphere, as far south as Mexico in North America and Thailand in Asia. Description Species of ''Bistorta'' are perennial herbaceous plants. Their roots are fibrous, forming rhizomes. They have erect, unbranched stems. Their leaves are usually longer than wide, mostly basal, but with some arranged alternately on the stems. The inflorescences are spikelike. The individual flowers have five white to purple-pink (rarely red) tepals. The flowers are bisexual, although the 5–8 stamens are sometimes poorly developed. There are three styles. The fruits are in the form of achenes, that are brown or dark brown, unwinged, and three-angled. The monoploid number of chromosomes, ''x'', is 11 or 12. Taxonomy In 1753, Carl Linnaeus divided up hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Garden Plants Of Asia
A garden is a planned space, usually outdoors, set aside for the cultivation, display, and enjoyment of plants and other forms of nature. The single feature identifying even the wildest wild garden is ''control''. The garden can incorporate both natural and artificial materials. Gardens often have design features including statuary, follies, pergolas, trellises, stumperies, dry creek beds, and water features such as fountains, ponds (with or without fish), waterfalls or creeks. Some gardens are for ornamental purposes only, while others also produce food crops, sometimes in separate areas, or sometimes intermixed with the ornamental plants. Food-producing gardens are distinguished from farms by their smaller scale, more labor-intensive methods, and their purpose (enjoyment of a hobby or self-sustenance rather than producing for sale, as in a market garden). Flower gardens combine plants of different heights, colors, textures, and fragrances to create interest and delight the s ...

Plants Described In 1825
Plants are predominantly Photosynthesis, photosynthetic eukaryotes of the Kingdom (biology), kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyte, Glaucophyta, and consists of the green algae and Embryophyte, Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and Fern ally, their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green colo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Tibet
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or ''skin flora''. 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 first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phyt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Pakistan
Pakistan's native flora reflects its varied climatic zones, which range from arid and semi-arid to temperate and tropical. For further details of habitats, see Ecoregions of Pakistan, Forestry in Pakistan and Wildlife of Pakistan. Distribution Northern highlands and valleys Pakistan has conifer forests in most of the northern and north-western highlands. These occur from 1,000 to 4,000 m altitudes. Swat, Upper Dir, Lower Dir, Malakand, Mansehra and Abbottabad districts of Khyber Pakhtunkhwa (formerly North-West Frontier Province) are the main areas covered with coniferous forests. Pindrow fir ('' Abies pindrow'') and Morinda spruce ('' Picea smithiana'') occupy the highest altitudes, deodar ('' Cedrus deodara'') and blue pine ('' Pinus wallichiana''), the intermediate heights, and chir pine ('' Pinus roxburghii''), occupy the lower areas. Eastern plains and deserts In most of Punjab and Sindh, the Indus plains have many fluvial landforms that support various natural bi ...

Flora Of Nepal
The Flora of Nepal is one of the richest in the world due to the diverse climate, topology and geography of the country. Research undertaken in the late 1970s and early 1980s documented 5067 species of which 5041 were angiosperms and the remaining 26 species were gymnosperms. The Terai area has hardwood, bamboo, palm, and sal trees. Notable plants include the garden angelica, ''Luculia gratissima'', ''Meconopsis villosa'', and ''Persicaria affinis''. However, according to ICOMOS checklist (as of 2006), in the protected sites, there are 2,532 species of vascular plants under 1,034 genera and 199 families. The variation in figures is attributed to inadequate floral coverage filed studies. There are 400 species of vascular plants which are endemic to Nepal. Of these, two in particular are orchids ''Pleione coronaria'' and ''Oreorchis porphyranthes.'' The most popular endemic plant of Nepal is rhododendron (arboreum) which in Nepali language is called ''lali guras''. See also * Fa ...

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 be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. 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. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists 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. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...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 enc ...
