Average growth of all trees was 39.2 feet in height and 9.2 inches in diameter, and there were no significant differences between trees of different ages or different sexes. The sex ratio was approximately 1:1, but 58 trees still had not been observed to flower. Four trees were considered to be monoecious, with a few female flowers produced on trees that were predominately male.
