Ulmus × hollandica 'Angustifolia'

Ulmus × hollandica 'Angustifolia' is one of a number of hybrids arising from the crossing of the Wych Elm U. glabra with a variety of Field Elm U. minor, first identified as Ulmus hollandica var. angustifolia by Weston in The Universal Botanist and Nurseryman 1: 315, 1770, and confirmed from herbarium specimens by Green as Ulmus × hollandica.

Description
The tree was chiefly distinguished by its narrow leaves.

Cultivation
No specimens are known to survive, but a hybrid cultivar matching the description of 'Angustifolia' was distributed by the Späth nursery of Berlin from the late 19th century as Ulmus montana 'Viminalis', and remains extant.
