PETUNIA VIOLACEA. 



Chap. VI. 



(raised from the Plants in Pot I., Table LXXIX.). Crossed and 

 self-fertilised seeds from plants of the last generation in Pot I., 

 in Table LXXIX., were placed on sand, and after germinating, 

 were planted in pairs on the opposite sides of four pots. Tho 

 seedlings when in full flower were measured to the base of the 

 calyx. The remaining seeds were sown crowded on the two 

 sides of Pot V. ; and the four tallest plants on each side of this 

 pot were measured in the same manner. 



Table LXXX. 



Petunia violacra (Fourth Generation; raised from Plants of the 



Third Generation in Pot P., Table LXXIX?). 



The fifteen crossed plants average 46 "79, and the fourteen 

 (one having died) self-fertilised plants 32 ' 39 inches in height ; or 

 as 100 to 69. So that the crossed plants in this generation had 

 recovered their wonted superiority over the self-fertilised plants ; 

 though the parents of the latter in Pot I., Tatle LXXIX., were a 

 little taller than their crossed opponents.
