The fruit is globular, always red, with soft flesh and skin that usually separates readily from pulp. Geographical.^—The species is a native of Europe and an occasional escape from cultiva- tion in this country. Groups of Sour Cherries.—The sour cherries include two general groups: 1. Amarelles.—These cherries are pale red in color, have colorless juice, and are generally somewhat flattened on- the ends. They have less acid than dark- colored cherries. Montmorency and Early Richmond are the most common Amarelles. 2. Morellos or Griottes.—These are cherries with dark red fruit and dark juice, and they vary from spherical to heart-shape. Common varieties are Ostheim, Olivet, Louis PhiUppe, and the Morello. Other Species of Cherries.—The species of cher- ries native to America are of little horticultural importance. Chief of these are P. pennsyhanica, P. emarginata, P. pumila, P. cuneata, and P. besseyi. P. pennsyhanica is sometimes used as a stock on which to bud the sour cherry. Prunus mahaleb, a native of Europe and Asia, is very extensively used in this country as a stock for all sweet and sour cherries. It is an excellent dwarfing stock. Uses.—Both sour and sweet cherries are used as a dessert fruit, and in the making of pies. The bulk of the cherries. Fig. 168.—Twig of sour cherry (Prunus cerasus). (After Pad- dock and Whipple.).
