A Report on Ulmus Pumila in the Great Plains Region of the United States
From a study of the history of oriental elms that have been planted in the Great Plains, the author concludes that Ulmus pumila should properly be called Siberian elm and U. parvifolia Chinese elm. Trees of U. pumila originating from seed collected from the southern part of the natural range in China have been found susceptible to winter-killing in the Great Plains. Only the hardy northern strain should be used in the future.
