The _flowers_, which are from one to two inches broad, are borne in clusters of 3 to 8, on wooly pedicels about an inch long. The white or rosy petals form a cup which surrounds the numerous stamens and the five styles. The calyx is pubescent. The _fruit_ ripens in October, forming a globose, pale green, very fragrant apple with a waxy surface. It is about an inch in diameter, flattened at each end. Like the other crabs, its handsome flowers have a delicious fragrance which makes the tree popular for planting for ornamental purposes. The fruit is sometimes gathered for jelly. The _wood_ is heavy, close-grained and reddish-brown. The wild sweet crab, _Malus coronaria_ Mill., differs from the above in having more nearly smooth leaves and calyx. It is rarely found in Illinois but is common in Ohio. A cultivated variety, _Malus ioensis plena_ Rheder, is sold under the name of Bechtel's crab, and has large, double, rosy-pink blossoms. +SERVICE BERRY+ _Amelanchier arborea_ (Michx. f.) Fern. (_Amelanchier canadensis_ Medic.) THE downy service berry, or shadblow, as it is more commonly called in the East, has little economic importance except for its frequency throughout the State and the touch of beauty its flowers give to our forests early in the spring before the foliage has come out. It is a small tree 20 to 50 feet high and seldom over 8 inches in diameter, with a rather narrow, rounded top but is often little more than shrub. The name shadblow was given by the early settlers who noticed that it blossomed when the shad were running up the streams. [Illustration: SERVICE BERRY One-half natural size.] The _bark_ is smooth and light gray, and shallowly fissured into scaly ridges. The _winter buds_ are long and slender. The _leaves_ are alternate, slender-stalked, ovate, pointed, finely toothed, 2 to 4 inches long, densely white-hairy when young, then becoming a light green, and covered with scattered silky hairs. The white _flowers_ appear in erect or drooping clusters in early spring, before the leaves, making the tree quite conspicuous in the leafless or budding forest. The petals are slender and rather more than a half inch long. The _fruit_ is sweet, edible, rounded, reddish-purple when ripe, 1/3 to 1/2 an inch in diameter, ripening early in June. Birds and denizens of the forest are very fond of the berries. The _wood_ is heavy, exceedingly hard, strong, close-grained and dark brown. It is occasionally used for handles. This is a desirable ornamental tree and should be planted for this purpose and to encourage the birds. The smooth service berry, _Amelanchier leavis_ Wieg., differs from the above species in having smooth leaves, dark green and slightly glaucous when mature, and they are half grown at flowering time. The fruit is sweet, purple or nearly black, glaucous and edible. +COCK-SPUR THORN+ _Crataegus crus-galli_ L.
