Abstract

An Amelanchier canadensis tree grown in a cultivated area of a nursery near Princeton, N.J., which tree is distinctly columnar in overall appearance in contrast to other Amelanchier canadensis trees which are much more spreading, the instant variety being resistant to leaf spot fungi which causes defoliation of the usual Amelanchier trees in warm, humid weather, and the very abundant blooms of the tree which substantially hide the branches, the fall colors of its leaves providing a mixture of reds and purples.

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 Amelanchier canadensis tree substantially as herein shown and described, characterized particularly as to novelty by its very narrow, upright growth, dark green foliage which is much more resistant to defoliation by leaf spot fungi, in warm, humid weather than other seedlings of the variety, its blooms, which though small are so densely borne as to hide the branches, and glowing mixture of red and purple shades of leaves in the fall.
