Buddleja Candida
''Buddleja candida'' is a small deciduous shrub widely distributed from north-east India through south east Xizang (Tibet) to the provinces of Sichuan and Yunnan in western China, growing on forest edges, in mountain thickets, and along riverbanks, at altitudes of 1000 – 2500 m. Named and described by Dunn in 1920, the shrub was introduced to cultivation in the west in 1928.Stuart, D. (2006). ''Buddlejas''. RHS Plant Collector Guide. Timber Press, Oregon, USA. Leeuwenberg opined that the species needed further field study to confirm its specific distinction from ''B. nivea'', to which it is very closely allied. Moreover, some herbaria specimens examined he considered possible hybrids of ''B asiatica'' and ''B. macrostachya''.Leeuwenberg, A. J. M. (1979) ''The Loganiaceae of Africa XVIII Buddleja L.

Stephen Troyte Dunn
Stephen Troyte Dunn (26 August 1868, Bristol - 18 April, 1938, Sheen, Surrey, England) was a British botanist. He described and systematized a significant number of plants around the world, his input most noticeable in the taxonomy of the flora of China. Among the plants he first scientifically described was ''Bauhinia blakeana'', the national flower of Hong Kong. Biography Born in Bristol in the family of Rev. James Dunn, of Northern Irish descent, S. T. Dunn was educated at Radley, and at Merton College, Oxford, where he earned his BA in classics. He was private secretary to liberal politician Thomas Acland in 1897, and the next year (as in 1898 Thomas Acland died) he first joined Kew as private secretary to the director, W. T. Thiselton-Dyer. He was then assistant for India in the herbarium from 1901 until his departure for Hong Kong in 1903. At Kew prior to this, he worked on compiling the second supplement of Index Kewensis that was issued in 1904-1905. While superinte ...

Thyrsus
A thyrsus /ˈθɜːrsəs/ or thyrsos /ˈθɜːrˌsɒs/ (Ancient Greek: θύρσος) was a wand or staff of giant fennel (''Ferula communis'') covered with ivy vines and leaves, sometimes wound with taeniae and topped with a pine cone, artichoke, or by a bunch of vine-leaves and grapes or ivy-leaves and berries, carried during Hellenic festivals and religious ceremonies. The thyrsus is typically associated with the Greek god Dionysus, and represents a symbol of prosperity, fertility, and hedonism similarly to Dionysus. Religious/Ceremonial use In Greek religion, the staff was carried by the votaries of Dionysus. Euripides wrote that honey dripped from the thyrsos staves that the Bacchic maenads carried. The thyrsus was a sacred instrument at religious rituals and fêtes. The fabulous history of Bacchus relates that he converted the thyrsi carried by himself and his followers into dangerous weapons, by concealing an iron point in the head of leaves. Hence his thyrsus is ... [...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 India (region)
The flora of India is one of the richest in the world due to the wide range of climate, topology and habitat in the country. There are estimated to be over 18,000 species of flowering plants in India, which constitute some 6-7 percent of the total plant species in the world. India is home to more than 50,000 species of plants, including a variety of endemics. The use of plants as a source of medicines has been an integral part of life in India from the earliest times. There are more than 3000 Indian plant species officially documented as possessing into eight main floristic regions : Western Himalayas, Eastern Himalayas, Assam, Indus plain, Ganges plain, the Deccan, Malabar and the Andaman Islands. Forests and wildlife resources In 1992, around 7,43,534 km2 of land in the country was under forests of which 92 percent belongs to the government. Only 22.7 percent is forested compared to the recommended 33 percent of the National Forest Policy Resolution 1952. The majo ...

Buddleja
''Buddleja'' (; ''Buddleia''; also historically given as ''Buddlea'') is a genus comprising over 140 species of flowering plants endemic to Asia, Africa, and the Americas. The generic name bestowed by Linnaeus posthumously honoured the Reverend Adam Buddle (1662–1715), an English botanist and rector, at the suggestion of Dr. William Houstoun. Houstoun sent the first plants to become known to science as buddleja ( ''B. americana'') to England from the Caribbean about 15 years after Buddle's death. Nomenclature The botanic name has been the source of some confusion. By modern practice of botanical Latin, the spelling of a generic name made from 'Buddle' would be ''Buddleia'', but Linnaeus in his ''Species Plantarum'' of 1753 and 1754 spelled it ''Buddleja'', with the long i between two vowels, common in early modern orthography.Linnaei, C. (1753). ''Species plantarum''. Impensis Laurentii Salvii, Stockholm. The pronunciation of the long i in ''Buddleja'' as ''j'' is a common ...

Hardiness Zone
A hardiness zone is a geographic area defined as having a certain average annual minimum temperature, a factor relevant to the survival of many plants. In some systems other statistics are included in the calculations. The original and most widely used system, developed by the United States Department of Agriculture (USDA) as a rough guide for landscaping and gardening, defines 13 zones by long-term average annual extreme minimum temperatures. It has been adapted by and to other countries (such as Canada) in various forms. Unless otherwise specified, in American contexts "hardiness zone" or simply "zone" usually refers to the USDA scale. For example, a plant may be described as "hardy to zone 10": this means that the plant can withstand a minimum temperature of 30 °F (−1.1 °C) to 40 °F (4.4 °C). Other hardiness rating schemes have been developed as well, such as the UK Royal Horticultural Society and US Sunset Western Garden Book systems. A heat zone (s ...

Stockbridge, Hampshire
Stockbridge is a small town and civil parish in the Test Valley district of Hampshire, England. It is one of the smallest towns in the United Kingdom with a population of 592 at the 2011 census. It sits astride the River Test and at the foot of Stockbridge Down. Description The town is situated on the A30 road, which once carried most of the traffic from London to Dorset, south Somerset, Devon and Cornwall in the South West, though today this route is less important than the A303 dual carriageway to the north. The bridge over the Test led to the town's name, a local legend suggested a coach stop stocked provisions, but it derives from an earlier bridge that was made of 'stocks' (tree trunks). Salisbury is by road; Winchester is by the B3049 road that joins the A30 nearby. The town's long high street was thus on a useful route between the two medieval cathedral cities. The town's civil parish has an area of . The town's street crosses the River Test, marking the border of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Longstock Park
Longstock Park is in the civil parish of Longstock in the Test Valley district of Hampshire, England, and forms part of the Leckford Estate (1520 ha.), wholly owned by the John Lewis Partnership. Description Formerly Longstock Manor, of medieval origins, the park was purchased by Sir Joshua East in 1849. On his death, the park passed to his sons Alfred and Arthur. In 1914, the park became the home of the Beddington family until 1945, when it was sold to John Spedan Lewis, founder of the John Lewis Partnership.

Ploidy
Ploidy () is the number of complete sets of chromosomes in a cell (biology), cell, and hence the number of possible alleles for Autosome, autosomal and Pseudoautosomal region, pseudoautosomal genes. Sets of chromosomes refer to the number of maternal and paternal chromosome copies, respectively, in each homologous chromosome pair, which chromosomes naturally exist as. Somatic cells, Tissue (biology), tissues, and Individual#Biology, individual organisms can be described according to the number of sets of chromosomes present (the "ploidy level"): monoploid (1 set), diploid (2 sets), triploid (3 sets), tetraploid (4 sets), pentaploid (5 sets), hexaploid (6 sets), heptaploid or septaploid (7 sets), etc. The generic term polyploidy, polyploid is often used to describe cells with three or more chromosome sets. Virtually all sexual reproduction, sexually reproducing organisms are made up of somatic cells that are diploid or greater, but ploidy level may vary widely between different or ...

Trichome
Trichomes (); ) are fine outgrowths or appendages on plants, algae, lichens, and certain protists. They are of diverse structure and function. Examples are hairs, glandular hairs, scales, and papillae. A covering of any kind of hair on a plant is an indumentum, and the surface bearing them is said to be pubescent. Algal trichomes Certain, usually filamentous, algae have the terminal cell produced into an elongate hair-like structure called a trichome. The same term is applied to such structures in some cyanobacteria, such as '' Spirulina'' and ''Oscillatoria''. The trichomes of cyanobacteria may be unsheathed, as in ''Oscillatoria'', or sheathed, as in ''Calothrix''. These structures play an important role in preventing soil erosion, particularly in cold desert climates. The filamentous sheaths form a persistent sticky network that helps maintain soil structure. Plant trichomes Plant trichomes have many different features that vary between both species of plants an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
