THE VASCULAE PLATs^TS OF THE EEGIOK 



In the following list of the vascular plants of the eastern 

 Penobscot Bay region in ]\raine, the nomenclature of the 

 Pteridophyta follows Christensen's Index Filicum' ; while 

 that of the Spermatophyta follows the Seventh Edition of 

 Gray's JManuaf, save where new species or varieties and 

 nomenclatorial changes have been made since its publication. 

 In the latter instances, wherever possible, the manual name 

 is given in brackets. 



The records are based for the most part on specimens col- 

 lected by the writer, a complete set of which has been de- 

 posited in the herbarium of the ]^ew England Botanical 

 Club. Further records made by other collectors, are in- 

 cluded whenever they are corroborated by herbarium speci- 

 mens. Among these may be mentioned the collections of 

 Graves^, Kidder, and Xorton\ referred to previously. In
