Ulmus 'Hertfordensis Latifolia'

The elm cultivar Ulmus 'Hertfordensis Latifolia' was listed by Loudon in Arboretum et Fruticetum Britannicum (1838) as "the broad-leaved Hertfordshire Elm",[1] and later mentioned, as Ulmus campestris hertfordensis latifolia, by Boulger in the Gardener's Chronicle (II.

Though susceptible to Dutch Elm Disease, field elms (see Green's conjecture above) and their hybrids produce suckers and usually survive in this form in their area of origin.

The Woodland Trust records a small number of mature U. minor and Ulmus × hollandica surviving in Hertfordshire.
