Ulmus Glabra 'Crispa Pendula'
The elm cultivar ''Ulmus'' 'Crispa Pendula', the weeping fernleaf elm, was listed in the ''Gardeners' Chronicle & New Horticulturist'' (1873) as ''Ulmus crispa pendula'', a variety of 'Crispa', itself described as "of the ''U. montana'' type". 'Crispa Pendula' may be synonymous with the cultivar 'Adiantifolia', which appears from herbarium specimens to have a leaf similar to, but narrower than, 'Crispa'. Green, however, treated 'Adiantifolia' as a synonym of 'Crispa'. Description 'Crispa Pendula' is similar to 'Crispa' but with narrower leaves and pendulous branches. Pests and diseases See under 'Crispa'. Cultivation The tree was in cultivation at the Canterbury Nurseries, Kent, in 1873. No specimens are known to survive, but it is possible that some surviving 'Crispa' are 'Crispa Pendula', as the latter cultivar is now unfamiliar, and as it is known that pendulous elms are marginally less likely to attract foraging Scolytus ''Scolytus'' is a genus of bark beetles (su ...

Cultivar
A cultivar is a type of cultivated plant that people have selected for desired traits and when propagated retain those traits. Methods used to propagate cultivars include: division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production. Most cultivars arise from purposeful human 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'': 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 that share the unique characteristics that define the cultivar. was coined as a term meaning "cultivated vari ...

Ulmus 'Crispa'
The elm cultivar ''Ulmus'' 'Crispa' 'curled', the leaf margin sometimes known as the Fernleaf Elm, arose before 1800 and was first listed by Willdenow as ''U. crispa'' (1809). Audibert listed an ''U. campestris'' Linn. 'Crispa', ''orme à feuilles crépues'' 'frizzy-leaved elm' in 1817, and an ''Ulmus urticaefolia'' 'nettle-leaved elm'in 1832; the latter is usually taken to be a synonym. Loudon considered the tree a variety of ''U. montana'' (1838). In the 19th century, ''Ulmus × hollandica'' cultivars, as well as those of Wych Elm, were often grouped under ''Ulmus montana''. Elwes and Henry (1913) listed 'Crispa' as a form of wych elm, but made no mention of the non-wych samara (see 'Description'). Hanham (1857) noted that in his day concave-leaved Field Elm, ''U. campestris concavaefolia'', was frequently mistaken for and sold as 'Crispa' in nurseries, "though there is a wide difference between them".Hanham, F.

Peter Shaw Green
Peter Shaw Green (11 September 1920–17 August 2009) was an English botanist. Early life Green was born in Rochester, Kent, the youngest son of John and Elizabeth (née Hainsworth) Green, his father a civilian engineer with the Royal Air Force. He was educated at Taunton School, before studying botany at King's College London. His studies were interrupted by the Second World War, in which he served as an Adjutant (Captain) in the Northumberland Fusiliers, initially training recruits to shoot, but later joining his regiment in Italy, where he contracted typhoid. Upon recovery, he was despatched to Greece. In 1946, while still in uniform, he married Winifred Brown, whom he had met at King's College before the war. After demobilization, he returned to his studies at King's College. Career After graduation, Green was appointed Assistant Lecturer at Birmingham University before joining the Royal Botanic Garden, Edinburgh in 1952. In 1961, he moved to the Arnold Arboretum of Ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arnold Arboretum
The Arnold Arboretum of Harvard University is a botanical research institution and free public park, located in the Jamaica Plain and Roslindale neighborhoods of Boston, Massachusetts. Established in 1872, it is the oldest public arboretum in North America. The landscape was designed by Charles Sprague Sargent and Frederick Law Olmsted and is the second largest "link" in the Emerald Necklace. The Arnold Arboretum's collection of temperate trees, shrubs, and vines has a particular emphasis on the plants of the eastern United States and eastern Asia, where arboretum staff and colleagues are actively sourcing new material on plant collecting expeditions. The arboretum supports research in its landscape and in its Weld Hill Research Building. History The Arboretum was founded in 1872 when the President and Fellows of Harvard College became trustees of a portion of the estate of James Arnold (1781–1868), a whaling merchant from New Bedford, Massachusetts.

William Masters (botanist)
William Masters (1796–1874) FHS was an English nurseryman, garden designer, and amateur botanist. Born at Canterbury on 7 July 1796, he founded a nursery in St. Peter's St., Canterbury, initially known as St Peter's Nursery Ground (Kent Gazette 1816), later as Master's Botanical Garden and Nursery Ground (Stapleton's Directory 1838), and later still as Master's Exotic Nursery. Masters specialized in the cultivation of exotic plants, and experimental hybridizations. He also founded the Canterbury Museum, of which he was Hon. Curator from 1823 to 1846. Masters replanted much of the Dane John Gardens in Canterbury with stock donated from his nursery, and also designed several of the terraces in the middle of the formal garden at Walmer Castle. However, Masters is chiefly remembered for his catalogue ''Hortus duroverni'' of 1831, which comprehensively listed and classified many seeds and plants. Desmond, R. (1994).

Scolytus
''Scolytus'' is a genus of bark beetles (subfamily Scolytinae). It includes several species notorious for destroying trees in the forests. The Dutch elm disease is spread in North America by two species : the native elm bark beetle, ''Hylurgopinus rufipes'', and the European elm bark beetle, '' Scolytus multistriatus''. In Europe, while the aforementioned '' Scolytus multistriatus'' again acts as vector for infection, it is much less effective than the large elm bark beetle '' Scolytus scolytus''. Species Species include: *'' Scolytus amygdali'' Guerin, 1847, the almond bark beetle *''Scolytus dentatus'' Bright, 1964 *''Scolytus fagi'' Walsh, 1867 *'' Scolytus jacobsoni'' Spessivtzev, 1919 *''Scolytus laricis'' Blackman, 1934, the larch engraver *''Scolytus mali'' ( Bechstein, 1805), the larger shothole borer *'' Scolytus monticolae'' Swaine, 1917 *'' Scolytus multistriatus'' (Marsham, 1802), the European elm bark beetle, smaller European elm bark beetle *'' Scolytus muticus ...

Wych Elm Cultivar
Salt, also referred to as table salt or by its chemical formula NaCl (sodium chloride), is an ionic compound made of sodium and chloride ions. All life depends on its chemical properties to survive. It has been used by humans for thousands of years, from food preservation to seasoning. Salt's ability to preserve food was a founding contributor to the development of civilization. It helped eliminate dependence on seasonal availability of food, and made it possible to transport food over large distances. However, salt was often difficult to obtain, so it was a highly valued trade item, and was considered a form of currency by certain people. Many salt roads, such as the via Salaria in Italy, had been established by the Bronze Age. All through history, availability of salt has been pivotal to civilization. In Britain, the suffix "-wich" in a place name sometimes means it was once a source of salt, as in Northwich and Droitwich, although other - wich towns are so named from ...
