The putative Wych Elm cultivar Ulmus glabra 'Holgeri' originated in Sweden, where it was described by Holger Jensen of Ramlösa Plantskola, Helsingborg, in 1921.Späth-Buch, 1720-1920 : Geschichte und Erzeugnisse der Späth'schen Baumschule, p.230 (Berlin 1921) It was distributed by the Späth nursery of Berlin in the 1920s and '30s as Ulmus montana Holgeri.Späth, L., Catalogue 230 (1927-28; Berlin), p.79 Späth used U. montana both for wych and for U. × hollandica hybrids like 'Dampieri',RBGE Späth list 1902 so the name does not necessarily imply a wych cultivar. In The Netherlands the tree was classified as an Ulmus × hollandica hybrid,Christine Buisman, 'Verslag van de onderzoekingen over de iepenziekte, verricht in het phytopathologisch laboratorium Willie Commelin scholten te Baarn, gedurende 1932 (1)', Tijdschrift over Planteziekte, Vol 39 Iss 4, April 1933, p.85 a 1932 herbarium specimen from a tree in The Hague supplied by Späth being labelled Ulmus hollandica var. holgeri (Jensen).bioportal.naturalis.nl, specimen WAG.1847163
Description 'Holgeri' was described as straight and sturdy, of very strong growth, with beautiful dark green leaves. The herbarium specimen from The Hague appears to show hybrid leaves, without the abrupt tapering and "shoulder" of wych elm.
Pests and diseases Cultivars of both wych and U. × hollandica are susceptible to Dutch elm disease.
Cultivation No specimens are known to survive.
