Notable trees
Two possible mature specimens stood before Wright's Houses, Bruntsfield Links, Edinburgh (one survives, 2016). Despite being unpollarded open-grown trees, their branches were mostly steeply ascending, the fastigiate tendency being noticeable also in branchlets. Leaves and samarae typical of the species. Their planting close to buildings suggests that the plantsmen were aware that the trees were not the broad spreading 'Scotch Elm' ubiquitous in the city.
