 It is known that nurseries in Europe and America marketed the golden wych elm "Ulmus glabra" 'Lutescens' as "Ulmus americana aurea", and it is likely that Wesmael's "Ulmus americana variegata" was similarly misnamed, and perhaps derived from a reverting branch of "aurea", whose leaves it resembled.The "Ulmus americana variegata", "American variegated elm", marketed by the Klehm nursery of Arlington Heights, Illinois, in the early 20th century, may, however, have been variegated American white elm, as the nursery was famiar with the native species.Wesmael's herbarium specimen shows a young ‘Lutescens’-type leaf with mixed variegation and green (see ‘External links’).
