The Field Elm cultivar Ulmus minor 'Boissieri' , (Persian: نارون برگریز or نارون گلپشهای), found in Iran and identified by Irina Grudzinskaya as the species U. boissieri in 1977. The tree is endemic to the Zagros forests, with Quercus brantii, Celtis australis, Platanus orientalis, Fraxinus sp., and Cerasus mehaleb. The tree is also found in the provinces of Kermanshah (Qasr-e Shirin, Bisotun) and Kerman.

Richens however, treated U. boissieri as Ulmus minor.
By the proposed rule that known or suspected clones of U. minor, once cultivated and named, should be treated as cultivars, the tree would be designated U. minor 'Boissieri'.
