The elm cultivar Ulmus 'Fastigiata Glabra' was distributed by the Späth nursery, Berlin, in the 1890s and early 1900s as U. montana fastigiata glabra.[1][2][3] Späth used U. montana both for cultivars of wych elm and for those of some U. × hollandica hybrids like 'Dampieri'.[4] A specimen of U. montana fastigiata glabra in the Royal Botanic Garden Edinburgh was determined by Melville in 1958 as a hybrid of the U. × hollandica group.[5]

Description

Späth's name implies that when young, at least, the tree had an upright form and smooth leaves.

  • Bark of C2715, Edinburgh (see 'Cultivation')

Pests and diseases

Not known. Some examples of the U. × hollandica group possess a moderate resistance to Dutch elm disease.[6]

Cultivation

One tree supplied by Späth was planted in 1898 as U. montana fastigiata glabra at the Dominion Arboretum, Ottawa, Canada.[7] Three were supplied to the Royal Botanic Garden Edinburgh in 1902. One, in the Garden proper (tree C2715), was relabelled by Melville in 1958 U. glabra Huds. × U. carpinifolia [:U. minor ] × U. plotii [:U. minor 'Plotii' ];[5][8] it survived till the 1990s. Others may survive in Edinburgh, as it was the practice of the Garden to distribute trees about the city (viz. the Wentworth Elm);[9] the current list of Living Accessions held in the Garden per se does not list the plant.[10]

Putative specimen

An old glabrous-leaved hybrid elm in a more exposed position on The Mound, Edinburgh (2020), appears to match the 1958 RBGE herbarium leaf-specimen of U. montana fastigiata glabra (see 'External links' below) and may be a more spreading example of the cultivar.
