 An early 20th-century photograph in "Schedae ad Herbarium florae URSS" (1922), shows that 'Umbraculifera' ('Bubyriana') is not dissimilar in appearance to its putative hybrid "Ulmus" 'Androssowii'.The tree is as vulnerable to Dutch elm disease as the species.The tree was introduced to the Caucasus, Armenia and Turkestan, and it remains in cultivation in central and south-west Asia.
