* I suspect that by mistake I 

 fertilised this flower in compart- 

 ment VI. with pollen from the 

 shortest stamens of the long-styled 

 form, and it would then have 

 yielded about 64 seeds. Flowers 



to be thus fertilised were marked 

 with black silk ; those with pollen 

 from the mid-length stamens of 

 the short^styled with black thread; 

 and thus probably the mistake 

 arose.
