| - The wych elm cultivar Ulmus glabra Huds. 'Superba', Blandford Elm, with unusually large leaves, was raised by Gill's of Blandford Forum, Dorset, in the early 1840s as Ulmus montana superba and was quickly distributed to other UK nurseries. It was confirmed as a form of wych, and first described, by Lindley in The Gardeners' Chronicle, 1845, later descriptions being added by Gill (1845) and Morren (1848), who called it U. montana var. superba. Morren had adopted the name 'Superba' from the Fulham nurseryman Osborne in 1844, who supplied him with the tree – presumably one of the nurseries supplied by Gill. Morren states that 'Superba', already in cultivation in England, was introduced to Belgium by Denis Henrard of Saint Walburge, Liège, that in 1848 it had been present in Belgium for only three years, and that this variety was the one described as 'Superba' by Osborne, whom Henrard had visited at his nursery in Fulham in September 1844. 'Blandford Elm', with leaves of the same dimensions, was soon for sale in the USA (see 'Cultivation'). The Späth nursery in Berlin supplied a large-leaved U. montana superba from 1885 to the 1930s. H. Jensen examined the tree at Späth's nursery and confirmed (1912) that it was identical to Morren's Ulmus montana superba. Späth's catalogue of 1911–12, however, had erroneously claimed that a U. praestans E. Schoch was synonymous with Morren's U. montana superba. , who received specimens of U. praestans from Kiessling of the Magdeburg city nursery in 1908, said (1912) that "Ulmus montana superba, supposedly the same [as U. praestans], looks quite different when young, being wide with large, broad, dull green leaves, whereas ... U. praestans show an elongated medium-sized shiny green leaf and densely pyramidal crown". He concluded that U. praestans was not Ulmus montana superba. Späth admitted the error in an article in Möller's Deutsche Gärtner-Zeitung (1912), where he stated that U. praestans E. Schoch was an Ulmus × hollandica hybrid, and implied that Morren's tree was a form of U. montana (wych elm). In later catalogues the nursery distinguished between Morren's Ulmus montana superba and the hybrid U. praestans E. Schoch (for which he adopted Henry's synonym Ulmus superba Henry), marketing both cultivars in the post-war period. Späth was not the only botanist to confuse wych and hybrid 'Superba'. Though Loudon in his description (1838) of Canterbury Elm, Ulmus montana glabra major, had made no reference to large leaves, Boulger tentatively (1881) and Green more confidently (1964) equated Canterbury Elm with Morren's U. montana var. superba, a synonym not included in Rehder's lists (1915 & 1949). Loudon's description of Canterbury Elm, a fast-growing hybrid like Huntingdon Elm, holding its leaves late, does, however, match descriptions of U. × hollandica 'Superba' [U. praestans]. (en)
