 The Herbarium of the Arnold Arboretum holds a leaf-spray and samara specimen of an "Ulmus glabra" 'Dovaei' (spelled 'Davaei') sourced from the Ellwanger & Barry nursery.The leaves shown in this spray have petioles longer than the wych type (which are shorter than 5 mm) while the samarae are intermediate, confirming that the source tree, whether 'Dovaei' or not, was hybrid.
