Other native American ash trees

The other native sorts are the Red ash (F. tomentosa), with the bark of a deep brown tint, found in Pennsylvania: the Green ash (F. viridis), which also grows in Pennsylvania, and is remarkable for the brilliant green of both sides of the leaves: the Blue ash (F. Quadrangulata), a beautiful tree of Kentucky, 70 feet high, distinguished by the four opposite membranes of a greenish color, found on the young shoots: and the Carolina ash (F. platycarpa), a small tree, the leaves of which are covered with a thick down in spring.
