Plum.— Tvfo common strains of plums exist— the Eu- 

 ropean {domestica) and the American {amencana), each 

 originating from wild species of which there are many. The 

 plum was early domesticated, probably m the Mediter- 

 ranean basin. 



Peach.— Th.& peach probably originated in Persia or 

 India, but its wild form is not definitely settled. 



Grape.— The grape has been cultivated for several 

 thousand years, and it is believed that most of the present 

 varieties of the old world have descended from Viiis vini- 

 fera, which is probably indigenous to Asia. The American 

 cultivated varieties are derived from three native species, 

 V. rotundifolia, V. labrusca, and V. vulpina or riparia, or 

 by crossing with V. vinifera. The California grape is the 

 vinifera of Europe. 



Citrous Fruits. — The orange, lemon, lime, grape-fruit 

 and citron, although not known in the wild form, are 

 believed to have originated in Eastern Asia. They have 

 been cultivated for several thousand years. 



Strawberry. — Although there are a dozen wild species 

 only a few have ever been brought under cultivation. 

 From Keen's Seedling first known about 1821 most of the 

 modern strawberries have descended. This seedling was 

 derived from the Old Pine class which again was derived 

 from an American species, Fragaria chiloensis. In America 

 most of the modern varieties have come from Hovey's 

 Seedling, a derivation of Keen's Seedling. 



Rose. — The numerous varieties of roses have been 

 developed by hybridization and clonal or bud mutations of 

 many wild roses. The beautiful Hybrid Teas have risen 

 from four species — the chinensis, gallica, centifolia and 

 damascena. 



Sweet Pea. — The original of this cultivated plant came 

 from Ceylon in the pink and white Painted Lady. From 

 this, white, red, black scarlet, blue and yellow color muta- 

 tions as well as mutations in form, size, and habit have 

 arisen. Later extensive hybridization and selection have 

 developed the large number of forms of the present day. 



Boston Fern — This fern arose as a bud mutation from 

 Nephrolepis exaltata. By continued bud mutations of the 

 Boston fern, the numerous forms of the present day have 

 arisen.
