CRATJEGUS, genus of plants placed by American botanists in the apple family (Pomar cece). The genus includes about 50 species, natives of the north temperate zone, Mexico and the Andes of parts of Central America. The name is from the Greek, meaning and the plants are so called from the toughness of their wood. Twenty or more of the genus are found in North America. They are all large shrubs or small trees, more or less thorny; hence the name thorn, which is generally ap plied to them. The best-known American spe cies is C. crus-galli or cockspur thorn, a shrub or small tree with a maximum height of 30 feet, the thorns numerous and slender, which blossoms in May and June in thickets from western Quebec westward to Manitoba and southward to Florida and Texas. The wood is heavy, weighing about 45 pounds to the cubit foot. The hawthorn, hedge-thorn, May-bush or quickset is C. oxyacantha. The scarlet thorn,
haw or red haw is C. coccinea. It is a small tree, ,reaching 30 feet high, growing in the same region as C. crus-galli. The wood is hard, of a reddish brown color and weighs about 53 pounds per cubic foot. The azaroles (C. asara inr), natives of the Levant, are occasionally cultivated for their fruit, which is about the size of the Siberian crab, and is used either for dessert or for pies. C. orientalit (or odoratis sinsa) and C. tanacetifolia have also fruit of considerable size. The latter is much eaten in Armenia. C. mexicana has a large fruit, like a small apple, but not eatable. It is, however, very ornamental. The wood of most of the species much resembles that of the hawthorn. It is common to graft the rarer species on the hawthorn.
