PRINCIPLES OF PLANT-TERATOLOGY. 



Fasciation in " Fruits." — The strawberry (Fragaria 

 vesca) affords one of the best-known instances ol 

 fasciation; most of the " fruits" exhibited at shows 

 are examples of the fasciated receptacle of the flower,

 almost separated ; b, longitudinal section of fruit showing two 

 distinct stones. (G. S. Saunders.) 



with a differentiation of two apices, one at each end, 

 representing the incipient division into two distinct 

 ' 4 fruits." Or the " fruit " may be trifid : the equiva- 

 lent of three fruits, branching thus in two planes.

Fasciated or dichotomous fruits of cherry, plum (fig. 

 74), cherry-laurel (Primus Lauro-cerasus), and grape, 

 are common ; in the first three the fasciation is usually 

 of two, in the grape it may be of as many as seven parts 

 arranged in a circular plane (fig. 75). Fasciation is 

 common in many other fruits, e. g. the gourd (fig. 76), 

 gooseberry, orange, and apple.
