From Wikipedia, the free encyclopedia
The American Elm Ulmus americana cultivar 'Augustine' is a fastigiate, vigorous tree originally selected in Bloomington, Illinois, in 1927 [1]. Distinguished by its thicker branches and larger, more deeply-toothed leaves, it has proven particularly susceptible to Dutch elm disease, exhibiting 36 % crown dieback in one year after inoculation with the disease's causal fungus [2].
The tree is not known to have been introduced to Europe or Australasia.
