Cultivar 'Rugosa'
Origin Späth nursery, Berlin, Germany

The elm cultivar Ulmus 'Rugosa' was distributed by the Späth nursery, Berlin, in the 1890s and early 1900s as U. campestris rugosa. It is not known whether herbarium leaf-specimens from the Wageningen Arboretum originally labelled U procera 'Rugosa' and renamed U. carpinifolia (1962) show Späth's tree,[1] or whether Späth's 'Rugosa' is related to one listed by Hartwig and Rümpler in Illustrirtes Gehölzbuch (1875) as Ulmus montana (:glabra) var. rugosa Hort..[2]

Späth's 'Rugosa' appears to be distinct from a cultivar or cultivars of the wych elm named 'Rugosa'.


The U. campestris rugosa distributed by Späth was described as a corky field elm with branches standing out horizontally.[3]

Not known.


One specimen of Späth's U. campestris rugosa was planted in 1898 at the Dominion Arboretum, Ottowa, Canada;[4] given the two DED pandemics that have swept the North American continent in the 20th century, it is unlikely the tree still survives. Specimens supplied by the Späth nursery to the Royal Botanic Garden Edinburgh in 1902 as U. campestris rugosa may survive in Edinburgh as it was the practice of the Garden to distribute trees about the city (viz. the Wentworth Elm);[5] the current list of Living Accessions held in the Garden per se does not list the plant.[6]
