| Origin |
| USA |
The hybrid cultivar Willis originated as a selection made by a Mr Minnick of Kansas simply as a 'hybrid'. Almost certainly derived from a crossing of U. pumila × U. rubra, it was originally considered U. americana × U. pumila. It was described as having a smooth grey bark, large leaves similar to U. americana, and capable of very rapid growth. Marketed by the Willis Nursery Co., Ottawa, Kansas, circa 1959, it has not been widely tested for resistance to Dutch elm disease (Santamour & Bentz, 1995).
