"A new and distinct variety of Douglas-fir, Pseudotsuga menziesii, substantially as shown herein and described, characterized particularly by generally upright growth with a curving, twisting, non-directional, at times corkscrew-like pattern to stem and branches, and smaller than average size, while retaining the foliage color and foliage character of a normal Douglas-fir."
