by Heybroek in 1958 and cultivated at the Baarn elm research institute as clone P41. The tree survived till the 1960s. Like the Queens' College Chichester elms in Cambridge, the Magdalen College trees were not observed to produce root suckers, though The Grove at Magdalen has long been a deer park, and any sucker growth is likely to have been cropped. The Oxford zoologist Robert Gunther attributed the larger tree's unusual size to the fact (discovered in 1926) that it had been growing on a phosphate-rich bone-bed, made up of the remains of mammoths and other prehistoric animals. With a girth of 6.9 m (22.6 ft) and a height of , the Ulmus × hollandica hybrid elm on Great Saling Green, Great Saling, near Braintree, Essex, reckoned at least 350 years old, was reputedly the largest elm in England, before succumbing to Dutch Elm Disease in the 1980s; Elwes and Henry (1913) misidentified it as U. nitens (Ulmus minor). Examples of mature survivors in the East Anglian hybridisation zone include those near Royston, Hertfordshire, designated 'Elm of the Year, 2004' by Das Ulmen Büro. An example of the weeping form survives at Actons Farm, Sawbridgeworth, Hertfordshire. There are two notable TROBI Champion trees in the British Isles, one at Little Blakenham, Suffolk, measuring d.b.h. in 2008, the other at Nounsley, Essex, high by d.b.h. in 2005. The so-called W. G. Grace Elm, a majestic spreading hybrid (labelled just "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. It has been shown, however, to date from 1900. 'W. G. G.' had attained a spread round the middle of 31 m by 1982. Cultivars At least 40 cultivars have been recorded, although some may not have survived Dutch elm disease: Cultivars at one time or another identified as U. × hollandica, but which may have suffered misidentification through confusion with U. glabra Huds. cultivars that share the same name: 'Fastigiata Glabra', 'Fastigiata Macrophylla', 'Latifolia', 'Rugosa' In the 19th century and early 20th, Ulmus × hollandica cultivars (as well as those of wych elm) were often grouped under Ulmus montana. In art The elms in the Suffolk landscape-paintings and drawings of John Constable were "most probably East Anglian hybrid elms ... such as still grow in the same
