An arboretum in a general sense is a botanical collection composed exclusively of trees. More commonly a modern arboretum is a botanical garden containing living collections of woody plants and is intended at least in part for scientific study.
The Arnold Arboretum of Harvard University, established in 1872, is the oldest public arboretum in North America. This botanical research institution and free public park is located in the Jamaica Plain and Roslindale neighborhoods of Boston, Massachusetts. 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.
Ulmus laevisPall., 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. 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 consider it native. NB: The epithet 'white' elm commonly used by British foresters alluded to the timber of the wych elm.
Wilfrid Fox was a dermatologist in the United Kingdom. He practised at St George's Hospital, London.
Ernest Henry "Chinese" Wilson, better known as E. H. Wilson, was a notable British plant collector and explorer who introduced a large range of about 2000 Asian plant species to the West; some sixty bear his name.

The elm cultivar Ulmus 'Hillieri' arose from a chance seedling at Hillier's Pitt Corner nursery near Winchester, England, in 1918, and was marketed from 1928 as Ulmus hillieri, a name accepted by Christine Buisman in her 1931 labelling of a specimen in France. Since at least 1944 the tree has been determined a form of Ulmus × hollandica, its designation at Kew Gardens, in Green, and in later Hillier catalogues. In 1940, 'Hillieri' was noted as being a hybrid of uncertain origin. Krüssmann notes that for a time the tree was listed by Hilliers as U. × hillieri.
The Siberian elm cultivar Ulmus pumila 'Hansen' is a little-known American tree of obscure origin, possibly raised from seed collected by the horticulturist and botanist Prof. Niels Hansen during his expedition to Siberia in 1897.
Hackfalls Arboretum is an arboretum in New Zealand. It was founded in the 1950s by Bob Berry. Hackfalls Arboretum is part of “Hackfalls Station”, a sheep and cattle farm of about 10 square kilometres, owned by the Berry family. Hackfalls is situated in Tiniroto, a tiny village in the eastern part of the North Island, between Gisborne (town) and Wairoa.
The area of the arboretum is 0.56 km2. It stretches along the borders of two lakes. It holds about 3,500 species of trees and shrubs. The collection contains many different oaks "spaced in rolling pastureland, allowing each to develop fully, and limbed up to enable grass to grow underneath". Most important part of the collection are about 50 different taxa of Mexican oaks.
Eastwoodhill is the national arboretum of New Zealand. It covers 131 hectares (1.31 km2) and is located 35 km northwest of Gisborne, in the hill country of Ngatapa. It was founded in 1910 by William Douglas Cook. Cook's life work would become the creation of a giant collection of Northern Hemisphere temperate climate zone trees in New Zealand – a dream that would eventually cost him all his money – buying and importing thousands of trees from New Zealand and British nurseries.
Swettenham is a village and civil parish in the unitary authority of Cheshire East and the ceremonial county of Cheshire, England. According to the 2001 Official UK Census, the population of the entire civil parish was 248, increasing to 291 at the 2011 Census. The civil parish includes the hamlet of Kermincham.
Windlesham Arboretum is between the villages of Windlesham and Lightwater in Surrey, United Kingdom. The arboretum features lakes, monuments, follies, a small chapel and approximately 22,000 mature and rare trees. The Windle Brook runs through the arboretum and has seven main footbridges and approximately ten ponds on each side, some of which are more properly identifiable as lakes based on size. The land and lakes, including a scattered number of buildings altogether consist of just over 1 square kilometre (0.39 sq mi).
The Lindsay Pryor National Arboretum is an arboretum on the Yarramundi Reach peninsula in Canberra, the capital of Australia. It is named after Lindsay Pryor, a noted Australian botanist. The site is located at the western end of Lake Burley Griffin and is used for research and recreation.
The Ulmus pumila cultivar 'Aurescens' was introduced by Georg Dieck at the National Arboretum, Zöschen, Germany, circa 1885. Dieck grew the tree from seed collected in the Ili valley, Turkestan by the lawyer and amateur naturalist Vladislav E. Niedzwiecki while in exile there. Dieck originally named the tree U. pinnato-ramosaf.aurescens.
The Field Elm cultivar Ulmus minor 'Viminalis' (:'willow-like'), occasionally referred to as the Twiggy Field Elm, was raised by Masters in 1817, and listed in 1831 as U. campestris viminalis, without description. Loudon added a general description in 1838, and the Cambridge University Herbarium acquired a leaf specimen of the tree in 1866. Moss, writing in 1912, said that the Ulmus campestris viminalis from Cambridge University Herbarium was the only elm he thought agreed with the original Plot's elm as illustrated by Dr. Plot in 1677 from specimens growing in an avenue and coppice at Hanwell near Banbury. Elwes and Henry (1913) also considered Loudon's Ulmus campestris viminalis to be Dr Plot's elm. Its 19th-century name, U. campestris var. viminalis, led the cultivar to be classified for a time as a variety of English Elm. On the Continent, 'Viminalis' was the Ulmus antarcticaHort., 'zierliche Ulme' [:'dainty elm'] of Kirchner's Arboretum Muscaviense (1864).
The Tokai Arboretum was the first large-scale silviculture experimental station in Cape Town, South Africa. The area of the main Arboretum, at Tokai Park, is 14 ha. Several adjacent compartments extend the area to 26 ha. The Arboretum was declared a National Monument in 1985, on its 100th anniversary. It contains stands of Eucalyptus and other trees from the original silviculture experiments in South Africa. In the 1990s a Gondwana Garden was created to display the plants typical of the Cape 100 million years ago.
