io THE CAYUGA FLORA. 



Franklin's Ravine, Taughannock, etc. The form with alternate 

 more or less long petioled leaves is with the other, and especially 

 abundant at Negundo Woods. A form, tall — 25-35 cm - > with 2 leaves, 

 each with 3 broad rather simple leaflets, and purplish flowers, but 

 usually with the rootstocks of D. laciniata, is placed here by Dr. 

 Gray. This is the best disposition to be made of the numerous 

 forms of this abundant species, so far as its local specimens art- 

 concerned.
