FLORA OF VERMONT

LESSER FLORAS 



The natural congregations among wild plants furnish most interesting 

 problems to the botanist, and this interest deepens and the profit from the 

 study grows when one seeks beyound the mere fact of the occurrence of 

 certain plants in certain localities for the explanation of such occurrence. 

 It was hoped when this catalogue was planned that some more adequate 

 discussion of our flora might be given along these lines. Lack of space 

 and time alike forbid that this plan be carried out in full. All that can 

 now be attempted is the inclusion of the bare lists of a few of the more 

 important of these lesser floras.
