[3] An Ulmus campestris cucullata, of uncertain species, had appeared in Loddiges' 1823 list,[4] but Loudon's brief description (1838) of concave- and hooded-leaved elms[5] was insufficient for later botanists to distinguish them.

[7] The Kissena nurseries (Parsons & Sons) of New York (1903) described the leaves of their Ulmus campestris cucullata as "deeply curled like a hood, and sharply notched along the edges".

[1] Herbarium specimens show an up-curling wych leaf with a shorter petiole, more deeply toothed margin, and more acuminate apex than 'Webbiana'.

[9] The samara was confirmed by the Royal Botanic Garden Edinburgh in 2017 as U. glabra Huds..[10] The tree is susceptible to Dutch elm disease.

[21] A specimen stood till 2017 (girth 2.8 m) in East Preston Street Cemetery, Edinburgh, before succumbing to DED.
