THE CLASSIFICATION OF PLUMS 183 



I. EUROPEAN GARDEN PLUMS (Prunus doinestica}. 

 Leaves large, coarse, rough, thick, usually pubescent 

 beneath, coarsely serrate; flowers large, white, showy; 

 fruit various; stone large, usually compressed and 

 roughened. This group contains several important 

 types, the most conspicuous being the following: 



1. REINE CLAUDE TYPE. Leaves comparatively 

 large, broad, and flat, with very coarse serrations; fruit 

 nearly spherical, green or tardily turning to a dull, 

 creamy yellow, flesh rather firm or even hard, green, 

 clinging to the stone. Bavay, Green Gage, McLaugh- 

 lin, Imperial Gage, Jefferson, Lawrence, and many 

 other varieties belong here. 



2. DAME AUBERT TYPE. Tree large; leaves large, 

 coarse; fruit very large, oval, compressed, with more 

 or less of a neck; flesh yellow. Yellow Egg (Magnum 

 Bonuni] and Golden Drop represent this type. 



3. THE PRUNES. Fruit medium to large, always 

 oval or ellipsoid, usually with one side of the oval 

 straighter than the other, compressed; color blue or 

 purple; flesh mostly greenish-yellow, firm; stone 

 usually free in a large cavity. Represented best by 

 Fellenberg and German Prune. 



4. THE PERDRIGONS. Fruit medium to large, 

 spherical or oblate, sometimes distinctly depressed at 

 the apex, usually with a deep suture, blue or purple; 

 flesh greenish-yellow, rather firm. Not well repre- 

 sented in America, but typified in Goliath and Royal 

 Tours. 



5. DIAMOND TYPE. Fruit mostly large, oval, very 

 slightly compressed, always dark solid blue in color, 

 with a heavy bloom which also appears to be blue;
