| Genus | Ulmus |
| Cultivar | 'Hertfordensis Latifolia' |
| Origin | England |
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. 12: 1879), but without description.[2] It was considered "probably U. carpinifolia" (:U. minor) by Green,[3] though broad leaves point to a possible Ulmus × hollandica hybrid identity. Hybrids of this type were once common in eastern Hertfordshire.[4][5]
Description
[edit]Loudon's "broad-leaved" epithet distinguished the tree from his narrow-leaved Hertfordshire elm, U. 'Hertfordensis Angustifolia'.

Pests and diseases
[edit]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.
Cultivation
[edit]The Woodland Trust records a small number of mature U. minor and Ulmus × hollandica surviving in Hertfordshire.[6]
