Practically the same results were obtained from the pollinated and un- 
pollinated specimens of Anemone japonica. 
As no trace of fruit formation could be found in any one flower out of 
an extremely large number which were examined and watched, it was 
evident that the pollen was infertile, and that all the specimens used were 
really unpollinated. The experiments serve to show, however, that in simi- 
lar pairs of gynaeceums the production of carbon-dioxide is very constant, 
although the respiratory quotient fluctuates quite appreciably. From the 
variation in the respiratory quotient it can be concluded that the variations 
shown in the case of Cheiranthus Cheiri are also independent of pollin- 
ation.
