 and leaves, late leaf-flush and late leaf-fall, taken with its south-west England provenance, suggest a link with the Cornish Elm Ulmus minor subsp. angustifolia, which shares these characteristics.

Description

The tree initially has an upright, columnar form, but later develops a large rounded crown and occasionally reaches 17 m in height. It is chiefly distinguished by its contorted leaves, < 11 cm long by 8 cm broad, which occasionally wrap around the branchlets and remain attached to the tree well into winter. 'Exoniensis' comes into leaf later than U. glabra and U. glabra sports such as 'Camperdownii' and 'Horizontalis', and keeps its foliage longer. Unlike 'Camperdownii' and 'Horizontalis', it does not produce large U. glabra-type samarae
