Note. 



-The stems which bore only flowers were not included in the mea- 

 suring because they were not full-grown ; they were included in the weigh- 

 ing because it was not worth while going over the whole set of stems to 

 exclude them. 



The numbers in the first compartment are 117, 193, because 2 plants 

 used for microscopic examination are here counted.
