Ronald Melville (botanist)
Ronald Melville (12 March 1903 – 6 August 1985) He was an English botanist, based at the Royal Botanic Gardens Kew. He is chiefly remembered for his wartime research into rosehips as a source of vitamin C, prompted by the epidemic of scurvy amongst children owing to the reduced importation of fresh fruit. His research concluded that hips from the common Dog Rose ''Rosa canina'' held the highest concentration of the vitamin. In later years, he challenged the two-species taxonomy of the British elms proposed by Richens,Richens, R. H. (1984) ''Elm'', Cambridge University Press. identifying five distinct species, several varieties and numerous complex hybrids.Melville, R. (1978).

Bristol
Bristol () is a city, ceremonial county and unitary authority in England. Situated on the River Avon, it is bordered by the ceremonial counties of Gloucestershire to the north and Somerset to the south. Bristol is the most populous city in South West England. The wider Bristol Built-up Area is the eleventh most populous urban area in the United Kingdom. Iron Age hillforts and Roman villas were built near the confluence of the rivers Frome and Avon. Around the beginning of the 11th century, the settlement was known as (Old English: 'the place at the bridge'). Bristol received a royal charter in 1155 and was historically divided between Gloucestershire and Somerset until 1373 when it became a county corporate. From the 13th to the 18th century, Bristol was among the top three English cities, after London, in tax receipts. A major port, Bristol was a starting place for early voyages of exploration to the New World. On a ship out of Bristol in 1497, John Cabot, a Venetia ...

Acacia Melvillei
''Acacia melvillei'', commonly known as yarran, is a shrub of the genus ''Acacia'' and the subgenus ''Plurinerves'' that is endemic to south eastern Australia. Description The tree can grow to a maximum height of around and has glabrous branchlets. Like most species of ''Acacia'' it has phyllodes rather than true leaves. The evergreen, leathery and ascending phyllodes have a narrowly elliptic or oblong-elliptic shape and are quite straight with a length of and a width of and have many closely parallel, obscure nerves where one to three are more prominent than the others. It blooms between August and November producing inflorescences that occur in groups of three to five found on an axillary axis with a length of and has spherical flower-heads with a diameter of containing 30 to 50 densely packed bright yellow flowers. The straight, flat and papery seed pods that form after flowering have more or less straight sides but are constricted between some seeds. The pods are up to i ...

County Herb Committee
The County Herb Committees were a nationwide medicinal plant collecting scheme, established by the British Ministry of Health during the Second World War. History The County Herb Committees were set up at a time when the German occupation of France and the disruption of shipping lanes interfered with drug supplies. As in the First World War, the British found that the Germans still largely dominated the pharmaceutical industry and consequently by the early 1940s there were critical shortages of essential medicines in hospitals and homes across Britain. First the Vegetable Drugs Committee (VDC) of the Ministry of Supply was established in March, 1941, and the invovlement of the Royal Botanic Gardens, Kew, was led by Dr. Ronald Melville, an economic botanist and pharmacist. A total of 70 Committees were set up across England, Scotland and Wales, and grants of a total of £1,191 were made available to set up drying centres that could deal directly with trading companies.

Ulmus Canescens
''Ulmus minor'' subsp. ''canescens'' is a small deciduous tree occasionally known by the common names grey elm, grey-leafed elm, and hoary elm.

Ulmus Minor 'Coritana'
The Field Elm cultivar ''Ulmus minor'' 'Coritana' was originally claimed by Melville, while he was searching in the neighbourhood of Leicestershire in 1936 for ''U. elegantissima'', as a new species, which he called ''U. coritana''. He later recorded its distribution in the counties of Bedfordshire, Berkshire, Buckinghamshire, Cambridgeshire, Essex, Hertfordshire, Leicestershire, Nottinghamshire, Norfolk, Oxfordshire, Suffolk and Warwickshire. Richens, however, dismissed ''U. coritana'' as 'an artificial aggregate' of local forms of Field Elm. Bean noted (1988) that Melville's ''U. coritana'' was not recognised in the ''Flora of the British Isles'' as a species distinct from ''U. carpinifolia'' ''U. minor'' By the proposed rule that known or suspected clones of ''U. minor'', once cultivated and named, should be treated as cultivars, the tree would be designated ''U. minor'' 'Coritana'.

Ulmus Minor 'Plotii'
The Field Elm cultivar ''Ulmus minor'' 'Plotii', commonly known as Lock Elm or Lock's Elm (its vernacular names), Plot's Elm or Plot Elm, and first classified as ''Ulmus sativa'' Mill. var. ''Lockii'' and later as ''Ulmus plotii'' by Druce in 1907-11 (see 'Etymology'), is endemic mainly to the East Midlands of England, notably around the River Witham in Lincolnshire, in the Trent Valley around Newark-on-Trent, and around the village of Laxton, Northamptonshire. Ronald Melville suggested that the tree's distribution may be related to river valley systems, in particular those of the Trent, Witham, Welland, and Nene. Two further populations existed in Gloucestershire. It has been described as Britain's rarest native elm, and recorded by The Wildlife Trust as a nationally scarce species. 4 cm in length, with comparatively few marginal teeth, usually < 70; the upper surfaces dull, with a scattering of minute tubercles and hairs.

Ulmus Minor 'Goodyeri'
The Field Elm cultivar ''Ulmus minor'' 'Goodyeri', commonly known as 'Goodyer's Elm', was discovered by John Goodyer in 1624 at Pennington near the Hampshire coast between Lymington and Christchurch. No old specimens are known to survive, but the tree is perpetuated by numerous root suckers, notably in the lanes about the Alice Lisle public house in the New Forest hamlet of Rockford.Chatters, C. (2009). ''Flowers of the Forest - People and Plants in the New Forest National Park''. Wildguides. The tree has suffered misidentification in the centuries since its discovery, firstly by Philip Miller in his 'Gardeners' Dictionary' of 1731,Miller, P. (1731). ''The Gardener's & Botanist's Dictionary'', Vol. II, part 2 , Q–Z, p. 33. Private publication. and later in the early 20th century by Augustine Henry and Marcus Woodward, who both confused the tree with Plot Elm, whose centre of distribution is in the East Midlands, some 200 miles away and of completely different app ...

Linnean Society
The Linnean Society of London is a learned society dedicated to the study and dissemination of information concerning natural history, evolution, and taxonomy. It possesses several important biological specimen, manuscript and literature collections, and publishes academic journals and books on plant and animal biology. The society also awards a number of prestigious medals and prizes. A product of the 18th-century enlightenment, the Society is the oldest extant biological society in the world and is historically important as the venue for the first public presentation of the theory of evolution by natural selection on 1 July 1858. The patron of the society was Queen Elizabeth II. Honorary members include: King Charles III of Great Britain, Emeritus Emperor Akihito of Japan, King Carl XVI Gustaf of Sweden (both of latter have active interests in natural history), and the eminent naturalist and broadcaster Sir David Attenborough.

Botany
Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (''botanē'') meaning " pasture", " herbs" "grass", or " fodder"; is in turn derived from (), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – and later cultivate – ed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
