Abstract

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 sugar maple tree, substantially as herein shown and described, characterized by the unique combination of its relatively fast and dense growth, freedom from leaf tatter, numerous strategically placed branches, its abundance of thick, dark colored, leathery leaves, thick in comparison to most sugar maple trees, with more leaves on the compact oval crown, its relative ease of propagation and an excellent survival rate of buds throughout the winter months, with the leaves turning red, orange and pink in the Fall, the red color exhibiting ten to fourteen days prior to most sugar maple trees with leaves persisting for a longer period of time after the first killing frost than other sugar maple trees observed.
