The elm cultivar Ulmus 'Hertfordensis Angustifolia' was listed by Loudon in Arboretum et Fruticetum Britannicum (1838) as "the narrow-leaved Hertfordshire Elm",[1] and later mentioned, as Ulmus campestris hertfordensis angustifolia, by Boulger in the Gardener's Chronicle (II. 12: 1879), but without description.[2] It was considered "probably U. carpinifolia" (:U. minor) by Green.[3]
Loudon's "narrow-leaved" epithet distinguished the tree from his broad-leaved Hertfordshire elm, U. 'Hertfordensis Latifolia'.[4]
Though susceptible to Dutch Elm Disease, field elms (see Green's conjecture above) produce abundant suckers and usually survive in this form in their area of origin.
The Woodland Trust records a small number of mature U. minor surviving in Hertfordshire.[5]
