[7] A 1907 photograph shows an avenue of elms in Magdeburg, Germany, described in the accompanying article by Heinricy as U. praestans E. Schoch, a "hybrid between U. scabra [U. glabra] and U. campestris [U. minor]" – i.e. as a form of U.

A 'Superba' had appeared in Späth's catalogues from 1885,[13] from descriptions,[14] however, probably the large-leaved wych cultivar U. montana superba of Morren, not U. praestans.

He concluded that U. praestans was not Morren's Ulmus montana superba, but was indistinguishable in leaf or habit from the cultivar U. glabra Mill.

× hollandica hybrid, and implying that Morren's tree was a form of U. montana (Wych Elm), and corrected it in his later catalogues, distinguishing between Morren's Ulmus montana superba and U. praestans E. Schoch (for which he adopted Henry's synonym Ulmus superba Henry), and marketing both cultivars in the interwar period.

[19] Any link between Canterbury Elm (Loudon's U. montana glabra major), in cultivation in England throughout the 19th century (see below), and U. praestans E. Schoch, in cultivation in Europe in the late 19th century, is unknown, but Loudon's description of a fast-growing hybrid like Huntingdon Elm, holding its leaves late, matches descriptions of U. praestans.

Loudon described Ulmus montana glabra major, 'Canterbury Seedling', as a hybrid similar to Huntingdon Elm in bark and vigour, but more spreading in form, and holding its leaves late.

× hollandica cultivars, as a rapidly growing, narrow, pyramidal tree with smooth bark and steeply ascending branches.

Henry noted that a tree grown at Kew labelled U. montana macrophylla fastigiata was "similar in all respects" to Späth's 1900 'Superba'.

× hollandica hybrid U. praestans Schoch, which he said was synonymous with the U. superba Henry that he himself had supplied to Kew, as "a vigorous tree with upswept branches and large dark green foliage, lasting long into the autumn".

Berndt (1915) reported that "U. montana superba, a tree known in the Magdeburg region as Ulmus praestans", was "easy to confuse with" the similarly fastigiate but less vigorous U. glabra Mill.

[30] Henry noted that a tree grown at Kew labelled U. montana macrophylla fastigiata was similar in all respects to Späth's 'Superba'.

[13] A 'Superba' is not on any accessions list of identified surviving trees in the UK, save the specimen maintained as part of a low hedge at Wakehurst Place.

× hollandica with steeply ascending branches, which stood in Regent Road Park, Edinburgh, till 2017, had leaves that appeared to match the RBGE 1902 herbarium-specimen of U. montana superba.
