Chap. VI. CROSSED AND SELF-FERTILISED TLANTS. 195 



(raised from the Plants in Pot IV., in Table LXXIX.). Two 

 similar lots of seeds, obtained from the plants in Pot IV. in 

 Table LXXIX., in which the single crossed plant was at 

 first shorter, but ultimately much taller than its self-fertilised 

 opponent, were treated in every way like their brethren of tho 

 same generation in the last experiment. We have in the follow- 

 ing Table LXXXI. the measurements of the present plants. 

 Although the crossed plants greatly exceeded in height the self- 

 fertilised ; yet in three out of the five pots a self-fertilised plant 

 flowered before any one of the crossed ; in a fourth pot simul- 

 taneously ; and in a fifth (viz., Pot II.) a crossed plant flowered 

 first.

Petunia violacca (Fourth Generation ; raised from Plants of the 

 Third Generation in Pot IV, Table LXXIX.). 



The thirteen crossed plants here average 44*74, and the 

 thirteen self-fertilised plants 26-87 inches in height; or as 100 

 to 60. The crossed parents of these plants were much taller, 

 relatively to the self-fertilised parents, than in the last case ; and 

 apparently they transmitted some of this superiority to their
