The white lime (T. alba) is rare in the eastern states, but common in Pennsylvania and the states south of it. It is not a tree of the largest size, but its flowers are the finest of our native sorts. The leaves are also very large, deep green on the upper surface, and white below; they are more obliquely heart-shaped than those of the common basswood. The young branches are covered with a smooth silvery bark. This species is very common on the Susquehannah river.
