The _fruit_, or the haw, is large, nearly 3/4 inch across, bright crimson or scarlet in color. The edible sweet flesh is firm but mellow, surrounding 5 bony seeds. It is often used for making jelly. The _wood_ is strong, tough, heavy and hard, and is used for mallets, tool handles and such small articles. The Washington thorn, _Crataegus phaenopyrum_ Med., is a smaller tree, with bright red fruit, but its broad leaves are smooth and bright green. The flowers are small, in very large clusters, followed by small bright scarlet edible haws. In the southern half of Illinois, growing on moist river bottoms, the green haw, _Crataegus viridis_ L., becomes a tree 20 feet tall. The broad leaves are dark green and quite smooth. The fruit is small but produced in large clusters becoming bright red or orange-red as it ripens. +WILD PLUM+ _Prunus americana_ Marsh. THE common wild plum, or yellow plum, is a small tree which at a height usually of 3 to 6 feet divides into many spreading branches, often drooping at the ends. Not uncommonly it grows in thickets where it attains only large shrub size. The value of the tree lies in its fruit from which jelly and preserves are made, and its handsome form, and foliage, pure white fragrant flowers, and showy fruit which make it desirable for ornamental planting. [Illustration: WILD PLUM Three-quarters natural size.] The _leaves_ are alternate, oval, pointed, sharply toothed, (often doubly toothed) along the margin, thick and firm, 3 to 4 inches long by 1 to 2 inches wide, narrowed or rounded at the base, and prominently veined on both surfaces. The _flowers_ appear in numerous small clusters before, or simultaneously with, the leaves, and are white with small bright red portions in the center. The _fruit_, or plum, which ripens in late summer, is red or orange colored, about an inch in diameter, contains a stone or pit that is flattened and about as long as the pulpy part, and varies rather widely in its palatability. The _wood_ is heavy, hard, close-grained, reddish-brown in color and has no especial commercial uses. The Canada plum, _Prunus nigra_ Ait., is similar to the common wild plum, but the teeth of the leaves are blunt, the leaves are thin and the fruit is orange in color, almost without bloom. The wild goose plum, _Prunus hortulana_ Bailey, has thin lance-shaped leaves; its flowers have short petals and it has a rather hard, small globular fruit. +BLACK CHERRY+ _Prunus serotina_ Ehrh.
