THE STRAWBERRY. 603 



as indicated by the following diagram, S representing stami- 

 nate and P pistillate varieties : 



In selecting two varieties for this purpose, perfect fertiliza- 

 tion requires that their season of flowering should be nearly 

 at the same time. Hence early and late flowering sorts will 

 not succeed well together for this purpose. Nearly all sorts 

 most commonly cultivated at the present time are staminate, 

 and do not require this arrangement of beds for fertilization. 



VARIETIES. 



ARRANGEMENT. 

 CLASS I. SCARLET AND PINE STRAWBERRIES. 



Scarlet strawberries have small flowers ; leaves rather long, thin, 

 and light green, sharply serrate ; fruit bright color, acid or subacid, 

 seed deeply sunk. Pine strawberries are characterized by rather 

 large flowers, leaves broad, dark green, sometimes obtuse; fruit 

 large, not acid, rather smooth, seeds little sunk. These two sorts 

 have been much hybridized and crossed, until it is now difficult to 

 assign many varieties to either separately. 



Section /. Flowers Perfect. 

 Section II. Flowers Imperfect. 



CLASS II. ALPINE AND WOOD STRAWBERRIES. 



Flowers rather small, perfect ; leaves small, thin, light green ; fruit 

 small, sweet, parting freely from the calyx.
