 ly as this relation cannot be accounted for on 

 the assumption of an absolute disappearance, 

 something must remain from which the old fea- 

 tures may be restored. 



This lengthy discussion may be closed by the 

 citation of the cases, in which plants not only 

 show developmental features of a former state, 

 but also reproduce the special features, they 

 formerly had, but seemingly have lost. Two 

 good illustrative examples may be given. One 

 is afforded by the wheat-ear carnation, the
