2. Stones or papery carpels, two or more— 
e.g., Apple F : is : ‘ . Pome. 
Fie. XLI.—Achenial Fruits: 1, nut of Oak, also shown in section; 2, achene of 
Buckwheat; 3, double samara of Maple. 
VI. Aggregate fruits.—Polycarpellary; carpels always distinct. 
The forms of these are not well distinguished. In many Ranun- 
culacee there are numerous achenes on a pro- 
longed receptacle; in Magnolia numerous follicles 
are similarly arranged; in the raspberry many 
drupelets cohere slightly into a loose mass, which 
separates at maturity from the dry receptacle; in 
the blackberry similar drupelets remain closely 
attached to the fleshy receptacle; in the strawberry Berar Gren, 
there are many small achenes on the surface of the fleshy recep- 
tacle; finally, in the rose several to many achenes are inclosed 
within the hollow and somewhat fleshy receptacle.
