was much less difference between the two 

 forms. After describing the two forms of 

 Linum grandiflorum, which differ only in the 

 length of their pistils, he said that he had in 

 his garden two fine long-styled plants, sep- 

 arated by a considerable distance and some 

 evergreens from plants of the other form. He 

 marked twelve flowers on these two long-styled 

 plants, and put some short-styled pollen on 

 them ; but they, and the rest of the vast num- 

 ber of flowers on these two plants, had their 

 stigmas already covered with their own pollen, 

 and it was late in the season (September 15). 

 The pollen of the two forms could not be distin- 

 guished under the microscope. "Altogether," 

 said Darwin, "it seemed almost childish to 

 expect any result. Nevertheless, from my ex- 

 periments on Primula I had faith, and did not 

 hesitate to make the trial, but certainly did 

 not anticipate the full result that was obtained. 

 The germens of the twelve flowers swelled, and 

 bore six good capsules (the seed of which germi- 

 nated) and two bad ones; only four falling off. 

 All the other flowers were absolutely barren; 

 not even their germens swelled." 1 Not con- 

 tent with this striking result, he hunted down 

 this absolute sterility of the long-styled plants
