. Botany for high schools and colleges. Botany. 530 BOTANT. Tribe Prunece.—Trees and shrubs, witli stems yielding gum, simple, mostly serrate leaves, and solitary carpel ripening into a drupe. (Figs. 478-9.) Prunus communis, the Almond, is a native of Western Asia, and now grown in many warm-temperate countries for its fruits. Two principal varieties are grown, viz., Sweet and Bitter ; in the former the kernel is edible, whereas, in the latter, it is bitter and poisonous. An oil is expressed from both kinds. The Peach has been until recently regarded as a distinct species (P. Persica), but it is now supposed to have been derived from the Almond, by long culture and selection. P. Armeniaca, the Apricot, originally from Armenia, is now exten- sively grown in many countries. P. domestiea, the Plum of Europe, P. Americana, the Common Wild. Fig. 478. Pig. 478.—Flower cluster of Fnmus C&rasus. Fig. 4T9.—Section of flower of the Peach. Magnified. Fig. 479. Plum, of the Eastern United States, and P. Chicasa, of the Southern States, are cultivated for their excellent fruits. The second named is the original form of most of the varieties grown in the central part of the United States. The Cherry, commonly referred to P. Cerasus, is probably derived from P. avium, the Bird Cherry, of Europe. The wood of the Bird Cherry is used in Europe for making furniture, as is also that of our Wild Black Cherry (P. serotina), of the Eastern United States. Many of the foregoing have, by long and careful culture, developed double-flowered varieties, which are sometimes to be found in gardens. Prunus nana, the Dwarf Almond, is well known in the double- flowered state. Tribe Chrysobalanece, —Trees and shrubs, with simple, entire leaves. Mostly natives of tropical America, a few of tropical Asia and.
