Ulmus 'Hamburg'
The hybrid elm cultivar ''Ulmus'' 'Hamburg' was originally raised by the Plumfield Nurseries, Fremont, Nebraska, circa 1932, after its discovery by Mr. Lloyd Moffet in a bed of Siberian Elm ''Ulmus pumila'' seedlings from Tekamah. It was later marketed by Interstate Nurseries, Hamburg, Iowa, from 1948, as 'Interstate's New Hamburg Hybrid Elm'. Green stated that it was originally said be a hybrid of ''Ulmus pumila'' (female parent) and ''Ulmus americana'', but the Hamburg Nurseries of Iowa made no such claim for it in their catalogues from 1948 onwards. It is now considered more likely that ''Ulmus rubra'' was the male parent, as it was also known as 'Hybrid Chinese Elm', and therefore probably synonymous with Plumfield Nurseries' 'Hybrid elm' of the same date, a known crossing of ''U. pumila'' and ''U. rubra'', – and so, perhaps, also synonymous with ''Ulmus × intermedia'' 'Fremont', an elm of the same parentage found a little later in Plumfield Nurseries. An ''U. pumila'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ulmus
Elms are deciduous and semi-deciduous trees comprising the flowering plant genus ''Ulmus'' in the plant family Ulmaceae.

Ulmus Laevis
''Ulmus laevis'' Pall., variously known as the European white elm, fluttering elm, spreading elm, stately elm and, in the United States, the Russian elm, is a large deciduous tree native to Europe, from France northeast to southern Finland, east beyond the Urals into Kyrgyzstan and Kazakhstan, and southeast to Bulgaria and the Crimea; there are also disjunct populations in the Caucasus and Spain, the latter now considered a relict population rather than an introduction by man, and possibly the origin of the European population.Fuentes-Utrilla, P., Squirrell, J., Hollingsworth, P.

''U. laevis'' is rare in the UK, although its random distribution, together with the absence of any record of its introduction, has led at least one British authority to consi ...

Tree Register Of The British Isles
The Tree Register, or more fully, the Tree Register of the British Isles (T.R.O.B.I.), is a registered charity collating and updating a database of notable trees throughout Britain and Ireland. It comprises a computer database which in 2022 contained details of 250,000 trees. It contains data from the original hand-written records of the late and internationally acclaimed dendrologist Alan Mitchell, and other historical records taken from reference works going back more than 200 years. . Recent height and girth measurements can be compared to those recorded by the likes of Loudon (1830s), Elwes and Henry (early 1900s) and the Hon. Maynard Greville (1950s), providing a valuable record of growth rates. The Tree Register was one of the founders of the Ancient Tree Hunt campaign. See also *The Tree Council The Tree Council was founded in 1974 in the United Kingdom, and became a Charitable organization#Charity registration, registered charity in 1978.

Devon
Devon ( , historically known as Devonshire , ) is a ceremonial and non-metropolitan county in South West England. The most populous settlement in Devon is the city of Plymouth, followed by Devon's county town, the city of Exeter. Devon is a coastal county with cliffs and sandy beaches. Home to the largest open space in southern England, Dartmoor (), the county is predominately rural and has a relatively low population density for an English county. The county is bordered by Somerset to the north east, Dorset to the east, and Cornwall to the west. The county is split into the non-metropolitan districts of East Devon, Mid Devon, North Devon, South Hams, Teignbridge, Torridge, West Devon, Exeter, and the unitary authority areas of Plymouth, and Torbay. Combined as a ceremonial county, Devon's area is and its population is about 1.2 million. Devon derives its name from Dumnonia (the shift from ''m'' to ''v'' is a typical Celtic consonant shift).

Exeter
Exeter () is a city in Devon, South West England. It is situated on the River Exe, approximately northeast of Plymouth and southwest of Bristol. In Roman Britain, Exeter was established as the base of Legio II Augusta under the personal command of Vespasian. Exeter became a religious centre in the Middle Ages. Exeter Cathedral, founded in the mid 11th century, became Anglican in the 16th-century English Reformation. Exeter became an affluent centre for the wool trade, although by the First World War the city was in decline. After the Second World War, much of the city centre was rebuilt and is now a centre for education, business and tourism in Devon and Cornwall. It is home to two of the constituent campuses of the University of Exeter: Streatham and St Luke's. The administrative area of Exeter has the status of a non-metropolitan district under the administration of the County Council. It is the county town of Devon and home to the headquarters of Devon County Council. A p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ulmus × Intermedia 'Fremont'
The hybrid elm cultivar ''Ulmus × intermedia'' 'Fremont' is a little-known American hybrid cultivar propagated from a tree found on the Lloyd Moffet property (formerly the Plumfield Nurseries) at Fremont, Nebraska. The hybrid is believed to have arisen from a crossing of ''Ulmus pumila'' (female parent) and one of the spring-flowering elms native to North America,Dodge, A. F. (1960). ''Woody ornamental and shelter plants for the North Central Region 1954–1959: Five year report on regional plantings of Fremont Hybrid Elm''. USDA - ARS, Iowa State University, Ames, Iowa, USA probably ''Ulmus rubra''. The source tree was probably an unsold specimen of the Plumfield Nurseries' "Hybrid Elm", a cross between "Chinese elm" (as ''U. pumila'' was then called) and Red elm ''U. rubra'', briefly marketed from 1942 to 1943, but not appearing in later catalogues. This hybrid may have been the same as the cultivar sourced from Plumfield Nurseries at this time as "Hybrid Chinese Elm" and l ...

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.
