Ulmus laciniata var. nikkoensis
Also called Manchurian Elm
Ulmus laciniata var. nikkoensis Rehder, the Nikko elm, was discovered as a seedling near Lake Chūzenji, near Nikkō, Japan, and obtained by the Arnold Arboretum in 1905. The taxonomy of the tree remains a matter of contention, and has been considered possibly a hybrid of U. laciniata and U. davidiana var. japonica. However, in crossability experiments at the Arnold Arboretum in the 1970s, U. laciniata, a protogynous species, was found to be incompatible with U. davidiana var. japonica, which is protandrous.
Significantly, the variety was not recognized by Ohwi, though his reasons are not clear. Kew's 'Plants of the World Online' treats var. nikkoensis as a synonym of U. laciniata.
There are no known cultivars of this taxon, nor is it known to be in commerce beyond the United States.
