Flower, fruit and leaves one-half natural size.]

The _bark_ on the branches is smooth, thin and red-brown in color, while

on the trunk the thicker bark often breaks into scales. The twigs are at

first hoary-hairy, but soon become smooth and reddish.

The _leaves_ are alternate, simple, 3 to 4 inches long and almost as

broad. They are sometimes slightly lobed and sharply and deeply toothed.

They are dark green and shiny above, but pale and hairy beneath, borne

on stout, hairy petioles.

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.

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.

THE hawthorns, or thorn-apples, are small trees or shrubs of the apple

family which are widely distributed throughout the northeastern United

States, with fewer species in the South and West. In North America, no

less than 150 species have been distinguished, but their proper

identification is a task for the expert. There are about a dozen haws

that reach tree size in Illinois, attaining a height of 20 to 30 feet

and a stem diameter of 8 to 12 inches. Of these, perhaps the best known

is the cock-spur thorn with its many strong straight spines and shining

leaves. Its _bark_ is pale gray and scaly. Its _winter buds_ are small,

globose and lustrous brown.

The _leaves_ are conspicuous because of their dark green glossy surface.

They are broadest toward the apex tapering to the short petiole. They

vary in size in different localities, the smaller-leaved varieties seem

to be more frequently met with in the southern part of the State than in

the north. These leaves are alternate, wedge-shaped, notched on the

edges, and from 2 to 3 inches long.

The _flowers_ are rather small, arranged in flat-topped clusters, white

in color, with about a dozen pink stamens.

The _fruit_ is 1/3 inch thick, greenish-red; the flesh is hard and dry.

This haw is one of the best for planting for ornamental purposes; with

its spreading branches, it forms a broad, rounded crown. It is hardy and

succeeds in a great variety of soils.

The dotted hawthorn, _Crataegus punctata_ Jacq., also has wedge-shaped

leaves but they are leathery, dull gray-green in color with

conspicuous veins. The tree reaches a height of 25 feet with

distinctly horizontal branches forming a broad flat crown. It is often

almost without thorns. The fruit is oblong, dull red with pale dots,

becoming mellow.

The pear-thorn, _Crataegus calpodendron_ Med., is a smaller tree, with

broader leaves, very few thorns and pear-shaped fruit. The haw is

scarlet or orange-red, the flesh is thin and sweet.

+RED HAW+ _Crataegus mollis_ Scheele

LIKE almost all the hawthorns, the red haw is a tree of the pasture

lands, the roadside, the open woods and the stream banks. It is the

largest of our haws, occasionally reaching a height of 30 feet, with

ascending branches usually forming a low conical crown. The twigs are

hairy during the first season, but are soon smooth, slender, nearly

unarmed or occasionally armed with stout, curved thorns.
