Ulmus 'Hertfordensis Angustifolia'

The elm cultivar Ulmus 'Hertfordensis Angustifolia' was listed by Loudon in Arboretum et Fruticetum Britannicum (1838) as "the narrow-leaved Hertfordshire Elm", 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.

Description
Loudon's "narrow-leaved" epithet distinguished the tree from his broad-leaved Hertfordshire elm, U. 'Hertfordensis Latifolia'.

Pests and diseases
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.

Cultivation
The Woodland Trust records a small number of mature U. minor surviving in Hertfordshire.
