other means than by figures. For this reason 

 the result of the experhnents is expressed in 

 this way. 



I made six groups. The first includes tlie 

 cases where the whole circle is reduced to 

 small rudiments. The second shows 1-10 sec- 

 ondary capsules. The two following consti- 

 tute half a crown around the central fruit, the 

 third going up to this limit, the fourth going 

 from this limit to a nearly filled circle. Wholly 

 filled circles of secondary capsules without gaps 

 give the two last degrees, the fifth requiring 

 only continuity of the circle, the sixth display- 

 ing a large and bright crown all around the 

 central head. The fifth group ordinarily in- 

 cludes from 90 - 100 altered stamens, while the 

 sixth has from 100 - 150 of these deviating 

 parts. 



In ordinary cultures the third and fourth 

 group, with their interrupted crowns, predomi- 

 nate. Large crowns are rare and flowers which 

 at first sight seem to be wholly normal, occur 

 only under circumstances definitely known to be 

 unfavorable to growth, and to the development 

 of the anomalv. 



Having reached by this means a very simple 

 and easy method of stating the facts shown by 

 equal lots under contrasting influences, we will 

 now make use of it to inquire into the relation
