The
Wych Elm cultivar ''Ulmus glabra'' 'Grandidentata', listed as ''U. glabra'' var. ''grandidentata'' (
Moss), may have been the tree first described by
Dumortier in ''Florula Belgica'', 25, 1827, as ''U. corylacea'' var. ''grandidentata'' (:large-toothed hazel-like elm), in cultivation before 1830.
Green thought it a synonym of
'Cornuta'.
'Grandidentata' may be synonymous with
''U. glabra'' 'Corylifolia' (:hazel-leaved elm), which Green thought another synonym of 'Cornuta'.
Description
The name implies distinctively large marginal teeth, perhaps differing from the 'horns' of 'Cornuta'.
Pests and diseases
'Grandidenta' is susceptible to
Dutch Elm disease.
Cultivation
No authoritatively identified specimens are known to survive.
