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.
