Hybrid parentage U. glabra × U. minor
Cultivar 'Major'
Origin northern France and Low Countries; (as cultivar) England

Ulmus × hollandica 'Major' is a distinctive cultivar that in England came to be known specifically as the Dutch Elm, although all naturally occurring Field Elm Ulmus minor × Wych Elm U. glabra hybrids are loosely termed 'Dutch elm' (U. × hollandica). It is also known by the cultivar name 'Hollandica'.

A native of Picardy and northern France, where it was known from the fifteenth to nineteenth centuries as ypereau or ypreau,[1] the tree was introduced to England from the Netherlands in the late seventeenth century as a fashion-elm associated with William & Mary,[2] the name 'Dutch Elm' having been coined by Queen Mary's resident botanist Dr Leonard Plukenet.[3]

The epithet 'Major' was first adopted by Smith in Sowerby's English Botany 36: t. 2542, published in 1814, identifying the tree as Ulmus major. Krüssmann formally recognized the tree as the cultivar U. × hollandica 'Major' in 1962.[4]

Description

In areas unaffected by Dutch elm disease, 'Major' often attains a height of > 30 m, with a short bole and irregular, wide-spreading branches. In open-grown specimens, the canopy is less dense than that of the English elm or Wych elm. The bark of the trunk is dark and deeply fissured and, like English elm, forms irregular 'plates' in mature specimens, serving to distinguish it from the Huntingdon Elm (latticed bark), the other commonly planted U. × hollandica in the UK.[5]

The leaves are oval, < 12 cm long by 7 cm wide, the top surface dark green and glossy, with a long serrated point at the apex.[6] The red apetalous, perfect, wind-pollinated flowers are produced in spring in large clusters of up to 50. The obovate samarae are up to 25 mm long by 18 mm broad. The cultivar may be distinguished from other elms by the corky ridges which on mature trees occur only on the epicormic branches of the trunk. On immature trees and suckers, the corky bark is more pronounced.

The seed is rarely viable (Bancroft states that it is always sterile[7]), but the tree suckers profusely from roots.[1][8][9] In the south of Britain, 'Major' is commonly found as a sucker, sometimes in mixed hedgerows with English Elm. Large Dutch Elm sucker-populations have been found in south west Wales, Cornwall and along the south coast of England. The suckers of Dutch Elm are sometimes confused with those of English Elm, which may explain the widespread and random occurrence of the former in hedgerows in southern Britain. 'Major' comes into leaf some three weeks later than English elm, and loses its leaves some three weeks earlier, and when young, its branching is straighter, stouter and more open. It is usually more vigorous than English elm.[9] The larger, tapering leaves, predominantly corky bark, and bold herringbone outline of Dutch Elm suckers also help to distinguish them from those of English elm.

Pests and diseases

Ulmus × hollandica 'Major' is very susceptible to Dutch elm disease.

Cultivation

The ‘Dutch’ elm quickly became popular in eighteenth-century estate plantations in England, survivors today being naturalised relics of this planting fashion; but the tree was always rare in the Netherlands, where from the eighteenth century hollandse iep (Holland elm) meant the widely planted hybrid Ulmus × hollandica Belgica (Belgian Elm).[1] ‘Dutch’ elm was also planted in urban parks, for example in the elm-groves of Kensington Palace Gardens,[9] and, on account of its suckering habit and quick growth,[8] was frequently planted as the elm component in mixed coastal shelter-belts on the south coast, in Cornwall, South Wales, the Isle of Man,[10] and East Anglia.[9]

'Major' was introduced to Ireland, where the largest specimens were at Marlfield, County Tipperary,[9] renowned for its elms.[11] It was also the predominant elm in Phoenix Park, Dublin.[9] 'Major' is known to have been marketed (as U. montana gigantea) in Poland in the 19th century by the Ulrich nursery,[12] Warsaw, and may still survive in Eastern Europe.

In North America 'Major' is grown at several arboreta and along the streets of Portland, Oregon.[13] The cultivar is also grown in parks and avenues in Australia, notably in Melbourne,[14] and in New Zealand.[15] The two earliest Avenues of Honour in Australia, at Eurack (begun in 1916)[16] and Digby (begun 1917)[17] were both planted with Dutch Elm. The celebrated Avenue of Honour at Bacchus Marsh, Victoria, planted in 1918, is mainly of Dutch Elm grafted on to wych or English Elm.[18][19]

Owing to Dutch elm disease, mature trees are rare in the UK, except in Brighton and Hove, East Sussex; The Level, in Brighton, alone has over 80 specimens in a double avenue. Other examples, including the TROBI Champion (27 m high by 139 cm d.b.h. in 2009, after pollarding) can be seen in the city along the London Road. The specimen at Leeds Castle was, at 38 m, the tallest elm in surviving Britain until it blew down in 2000.[20]

There are also good examples in Edinburgh along Fettes Row, and one at the intersection of Royal Circus and Circus Place (bole-girth 2.5 m), while a single mature 'Major' survives at the extreme east end of East Princes Street Gardens (2015).[21] A 2011 study by Dr Max Coleman of the Royal Botanic Garden, Edinburgh, has confirmed that many thousands of mature 'Major' survive in the Isle of Man.[10]

Many old trees still survive in New Zealand, notably in Auckland, the finest considered to be the specimen found outside the Ellerslie Racecourse.[22][23]

The W. G. Grace Elm, a majestic spreading Dutch Elm, the last survivor (2009) of a ring of elms round East Oval, Ballarat, Victoria, was reputedly planted by W. G. Grace himself in 1874 during a tour by the England cricket team.[24] 'W. G. G.' had attained a spread round the middle of 31 m by 1982.[25]
