A. glandidosa. - Chinese Ailanthus, or Tree of Heaven. - This tree has large, elegant foliage, resembling the leaves of the Stag-horn Sumach, but on a much larger scale. There is one great objection to this tree, which will prevent its general introduction for shade: the flowers exhale a disagreeable odor, which taints the air to a great distance. It is said also to produce sickness. Whether this is the case or not, I cannot say; but I know that a tree in my neighborhood is a great nuisance when in bloom.
