A green ash tree which exhibits a rapid, straight, quick-branching, vigorous, upright, uniform and seedless growth habit which requires little or no pruning and produces a desirable nursery-grown tree for commercial sale in a minimum of growing time.

Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
I claim: 1. A new and distinct variety of green ash tree, substantially as shown and described herein, characterized particularly as to novelty by the unique combination of a rapid, straight, quick-branching, vigorous, upright, uniform and seedless growth habit which requires little or no pruning to produce a desirable nursery-grown tree for commercial sale in a minimum of growing time, with narrow glossy green leaves, an attractive bronze-color bark, a pronounced stronger caliper, a tendency to branch the first year of growth, and with leaves which stay on the tree longer in the autumn.
