greatest reduction is shown in Anemone, Clematopsis, Clematis, 
and Naravelia, that of the latter two being valvate. Apetaly also 
occurs in Enemion which is clearly a mere reduction from Isopyrum.

am suggesting the possible course of He ta of the ma 
groups and genera of thefamily Ranunculaceae. The dotted lines indicat 
genera showing parallel development in the two main ups. The distance 
from the base line is a rough indication of the relative primitiveness of 
each group, the basal groups of the Helleboroideae being considered more 
primitive than those of the Ranunculoideae.
