1922] Fernald— Notes on the Flora of Nova Scotia 179 



described by Roth, might be discussed, but enough has already been 

 emphasized to indicate that Roth 's detailed description of 0. tetragona 

 departs in very many points from 0. hybrida and that those who 

 wish to throw out Michaux's specific name must find an earlier name 

 which is more clearly synonymous with it than is 0. tetragona Roth.

 high; but in a peaty cove of Little Meteghan Lake the coarse stems 

 reached a height of 5.5 dm.
