Other characters: On the smaller branches there are irregular developments of cork as shown in [Fig. 76], projecting in some cases to half an inch in thickness.
Other common names: Red gum.
Comparisons: The cork elm is another tree that possesses corky ridges along its twigs, but this differs from the sweet gum in wanting the spiny fruit and its other distinctive traits.
American Linden (Tilia Americana)
Fig. 77.—Bud of the Linden Tree.
Distinguishing characters: The great distinguishing feature of any linden is the one-sided character of its bud and leaf. The bud, dark red and conical, carries a sort of protuberance which makes it extremely one sided as shown in [Fig. 77]. The leaf, [Fig. 78], is heart-shaped with the side nearest the branch largest.
