Ulmus glabra 'Corylifolia'
SpeciesUlmus glabra
Cultivar'Corylifolia'
OriginEurope

The putative Wych Elm cultivar Ulmus glabra 'Corylifolia' (: Hazel-leaved) was first described by Host[1] in Flora Austriaca (1827).[2] Another cultivar of the same name is described by Hugo Zapalowicz[3] in Conspectus Florae Galiciae Criticus (1908),[4] but was assumed to be 'Cornuta'.[5][6] Herbarium specimens confirm that more than one clone has been labelled 'Corylifolia', some with longish petioles and with fruit more typical of Ulmus × hollandica hybrids.[7]

Description

Host described the tree as having broad-ovate scabrid leaves, doubly toothed with broad, obtuse teeth.

Pests and diseases

See under Ulmus glabra.

Cultivation

No confirmed specimens are known to survive.

Putative specimen
