FLOWERING PLANTS OF NANTUCKET 431 
one hundred and fifty of these plants extend their northeastern 
limits, in many cases only locally, into Vermont, New Hampshire 
or Maine, and over seventy others, some of them unknown in 
Maine, occur as far to the east as the Canadian Maritime Prov- 
inces. A smaller group, very noteworthy in its isolation, are 
found at the extreme eastern extension of the continent in New- 
foundland.* 
The following plants of Nantucket do not appear to have 
been reported from any more northern or eastern point, and a 
considerable number of others have only within recent years been 
added to the known flora of the eastern Massachusetts main- 
land. The names used follow those of the catalogue, although 
some changes have since been adopted.
