Besides the above experiments, I fertilised a consi- 

 derable number of long-styled flowers with pollen, 

 taken by a camel's-hair brush, from both the mid- 

 length and shortest stamens of their own form : only 

 5 capsules were produced, and these yielded on an 

 average 14 "5 seeds. In 1863 I tried a much better ex- 

 periment: a long-styled plant was grown by itself, 

 miles away from any other plant, so that the flowers 

 could have received only their own two kinds of pol- 

 len. The flowers were incessantly visited by bees, and 

 their stigmas must have received successive applica- 

 tions of pollen on the most favourable days and at the 

 most favourable hours: all who have crossed plants 

 know that this highly favours fertilisation. This plant 

 produced an abundant crop of capsules; I took by 

 chance 20 capsules, and these contained seeds in 

 number as follows : —
