Mountain ash tree

A new and distinct variety of mountain ash tree substantially as herein shown and described, characterized particularly as to novelty by a unique combination of its rapid rate of growth, a trunk which for a tree of a given height is straighter than the trunk of a tree of an ordinary variety of similar height, larger foliage with dark green leaflets, a large proportion of the surface area of young petioles and newly formed branches is reddish color, and fall changes which occur approximately 2 to 3 weeks later than similar changes in ordinary varieties.
