The close relation between the organs of assimilation and the 

 stem classes is apparent; not only the absolute number of leaves 

 but their relative amounts show this relation. Weight and sur- 

 face of the single leaves as well as of the totality, show unmis- 

 takably their relation to light. These observations as well as 

 others by the author, lead to the conclusion (long ago assumed) 

 that the light conditions at least with tolerable species affect main- 

 ly the suppression of the lower stem classes.
