The elm cultivar Ulmus 'Hertfordensis Angustifolia' was listed by Loudon in Arboretum et Fruticetum Britannicum (1838) as "the narrow-leaved Hertfordshire Elm",Arboretum et Fruticetum Britannicum, 3: 1396 1838 and later mentioned, as Ulmus campestris hertfordensis angustifolia, by Boulger in the Gardener's Chronicle (II. 12: 1879), but without description. It was considered "probably U. carpinifolia" (:U. minor) by Green.
