The tree was first mentioned by Dieck, (Zöschen, Germany) in Haupt-Catalog der Obst- und Gehölzbaumschulen des Ritterguts Zöschen bei Merseburg 1885, p. 82, as U. scabra viminalis pulverulenta , but without description.

Description
Dippel [1], Illustriertes Handbuch der Laubholzkunde, 2:25, 1892 described it under the same name as having leaves streaked with both white and yellow.
Pests and diseases
'Pulverulenta' is very susceptible to Dutch elm disease.
Cultivation
Now extremely rare in cultivation, one tree grows at Batsford Arboretum, UK. Three specimens supplied by the Späth nursery of Berlin to the Royal Botanic Garden Edinburgh in 1902 as U. campestris 'Viminalis marginata' [sic], shown by herbarium specimens (see External links below) to have been 'Pulverulenta' or 'Variegata', may survive in Edinburgh, as it was the practice of the Garden to distribute trees about the city (viz. the Wentworth Elm); the current list of Living Accessions held in the Garden per se does not list the plant.
