Introduction
The original Quercus ×libanerris ‘Trompenburg’ has long been thought to be the specimen growing in the eponymous garden, Trompenburg Tuinen & Arboretum in Rotterdam, the Netherlands. For example, at the Harold Hillier Herbarium, the official herbarium of the International Oak Society, specimen No. 2179 of this cultivar is annotated as “Cultivated Trompenburg, original tree.” However, when revising the story of this cultivar, in connection with Allen Coombes and Roderick Cameron’s update of Quercus in Trees and Shrubs Online, we found that the tree at Trompenburg has a different origin and is morphologically different to the ortet. The original, described in 1959 and documented with herbarium specimens stored at Leiden and Wageningen herbaria, in fact grew at a nursery in the Netherlands.
