it was longer and had a more elongated and rougher 

 stigma, than in the other ; and the pollen-grains from 

 the latter were to those from the plant with a more 

 elongated pistil only as 100 to 88 in diameter, instead 

 of as 100 to 57. The corolla of the long-styled and 

 short-styled form differs in shape, in the same manner 

 as in P. veris. The long-styled plants tend to flower 

 before the short-styled. When both forms were legiti- 

 mately fertilised, the capsules from the short-styled 

 plants contained, on an average, more seeds than those 

 from the long-styled, in the ratio of 12'2 to 9'3 by 

 weight, that is, as 100 to 78. In the following table 

 we have the results of two sets of experiments tried 

 at different periods.
