Diagram showing ray-numbers at tiie bottom and ttie number 



for eacii of them at the left. The upper half is for 



the rich soil and the lower for poor soil. 



The accompanying diagram shows to the eye at a glance, 

 the results in terms of number of rays for the two soil conditions. 



In a neighbor's field, a few sunflowers of the branched type 

 were grown and upon these a record was made.

A small plant was found beneath and over-shadowed by a
