by bees with pollen from their own stamens produced 

 numerous capsules containing on an average 21 '5 

 seeds. 



Mid-styled form. Twenty-four flowers legitimately 

 fertilised by the stamens of corresponding length, 

 borne by the long and short-styled forms, yielded 96 

 (probably 100) per cent, of capsules, which contained 

 (excluding one capsule with 12 seeds) on an average 

 117-2 seeds. 



Fifteen mid-styled flowers fertilised illegitimately 

 by the longest stamens of the short-styled form yielded 

 93 per cent, of capsules, which (excluding four cap- 

 sules with less than 20 seeds) contained on an average 

 102-8 seeds. 



Thirteen mid-styled flowers fertilised illegitimately 

 by the mid-length stamens of the long-styled form 

 yielded 54 per cent, of capsules, which (excluding 

 one with 19 seeds) contained on an average 60*2 seeds. 



Twelve mid-styled flowers fertilised illegitimately 

 by their own-form longest stamens yielded 25 per 

 cent, of capsules, which (excluding one with 9 seeds) 

 contained on an average 77'5 seeds. 



Twelve mid-styled flowers fertilised illegitimate!) 

 by their own-form shortest stamens yielded not a 

 single capsule. 



Short-styled form. Twenty-five flowers fertilised 

 legitimately by the stamens of corresponding length, 

 borne by the long and mid-styled forms, yielded 72 

 per cent, of capsules, which (excluding one capsule 

 with only 9 seeds) contained on an average 70'8 

 seeds. 



Twenty short-styled flowers fertilised illegitimately 

 by the other stamens of the long and mid-styled forms 

 yielded only two very poor capsules. 



Twenty short-styled flowers fertilised illegitimately
