344 THE PLUM. 



firm, juicy, rich, nearly first-rate. Shoots vigorous, straight, 

 glossy reddish purple ; leaves dark green, crimpled. Ri- 

 pens the last week of summer. Productive in nearly all 

 soils. Long Island. 

 Hovey considers this identical with Cooper's Plum, of Coxe 

 and others. 



Nectarine. Large, regular, roundish; skin purple, bloom 

 blue; stalk half an inch long, stout; flesh dull greenish- 

 yellow, often tinged with red, rather coarse, rich, acid,

 nearly smooth, leaves broad. Quite distinct from the 

 Peach Plum of the preceding class. 



Royal Totjhs. (Syn. Royale de Tours.) Large, roundish, 

 suture deep, half round, one side swollen ; a white de-

 rather firm, juicy, rich, high-flavored, adhering closely 

 to the large, oval, flattened stone. Quite early; shoots 

 quite downy. Valuable for its earliness and good quali-

Section II. Fruit medium in size.

 peratrice of Boston, and disseminated as such, differs from 

 the true Imperatrice in its shorter and smaller neck, much 

 shorter and not sunk stalk, and more acid flavor. It is
