Ulmus × Hollandica 'Superba'
The hybrid elm cultivar ''Ulmus × hollandica'' 'Superba' is one of a number of intermediate forms arising from the crossing of the Wych Elm ''U. glabra'' with a variety of Field Elm ''U. minor''. Boulger tentatively (1881) and Green more confidently (1964) equated it with a hybrid elm cultivated in the UK by Masters at Canterbury in the early 19th century, known as "Masters' Canterbury Seedling" or simply the Canterbury Elm. Loudon examined a specimen sent by Masters and considered it a hybrid, calling it ''U. montana glabra major'' (not to be confused with ''U. major'' Smith, ''U.'' × ''hollandica'' 'Major').Hanham, F. (1857)''A Manual for the Park''(Royal Victoria Park, Bath). Longman, London. Green (1964) also equated Masters' Canterbury Elm with Osborne's ''U. montana'' var. ''superba'' (originally Gill's Blandford Elm, ''U. montana superba''), a wych cultivar with unusually large leaves described by Lindley in '' The Gardeners' Chronicle'', 1845, though Loudon ha ...

Ulmus × Hollandica
''Ulmus'' × ''hollandica'' Mill. , often known simply as Dutch elm, is a natural hybrid between Wych elm ''Ulmus glabra'' and field elm ''Ulmus minor'' which commonly occurs across Europe wherever the ranges of the parent species overlap. In England, according to the field-studies of R. H. Richens, "The largest area f hybridizationis a band extending across Essex from the Hertfordshire border to southern Suffolk. The next largest is in northern Bedfordshire and adjoining parts of Northamptonshire. Comparable zones occur in Picardy and Cotentin in northern France". Crosses between ''U.'' × ''hollandica'' and either of the parent species are also classified as ''U.'' × ''hollandica''. ''Ulmus'' × ''hollandica'' hybrids, natural and artificial, have been widely planted elsewhere.Bean, W. J. (1981). ''Trees and shrubs hardy in Great Britain'', 7th edition. Murray, LondonElwes, H.
