| Species | Ulmus glabra |
| Cultivar | 'Grandidentata' |
| Origin | Europe |
The Wych Elm cultivar Ulmus glabra 'Grandidentata', listed as U. glabra var. grandidentata (Moss),[1] may have been the tree first described by Dumortier in Florula Belgica, 25, 1827, as U. corylacea var. grandidentata[2] (:large-toothed hazel-like elm), in cultivation before 1830. Green thought it a synonym of 'Cornuta'.[3] 'Grandidentata' may be synonymous with U. glabra 'Corylifolia' (:hazel-leaved elm), which Green thought another synonym of 'Cornuta'.
Description
[edit]The name implies distinctively large marginal teeth, perhaps differing from the 'horns' of 'Cornuta'.
Pests and diseases
[edit]'Grandidenta' is susceptible to Dutch Elm disease.
Cultivation
[edit]No authoritatively identified specimens are known to survive.
Putative specimens
[edit]A mature open-grown large-toothed U. glabra cultivar, matching a 1903 herbarium leaf-specimen mislabelled U. montana cucullata,[4] stands in Niddrie Mains Road, Edinburgh (grafted at ground level; girth 1.4 m) (2016). The large teeth are present along the whole leaf-margin of short shoot-leaves as well as long ('Cornuta'). Though 'Cornuta'-like teeth may occur near the apex, they are rare, and do not resemble the slender 'horns' that usually appear in 'Cornuta' photographs. The tree is narrow-pyramidal, with upswept branches like a Huntingdon Elm.[5]
