1921] Fernald, — Expedition to Nova Scotia 185 



napolis County to Cape Breton, in the regions of calcareous or sweet 

 soils, are very rare in the acid western and southwestern counties 

 and, consequently, so far as our limited and somewhat negative 

 observations allow, special note is made of these plants. A large 

 number seen wherever we went, from Yarmouth to Cape Breton — 

 such species as Polypodium mdgare L., Polystichum acrostichoides 

 (Michx.) Sehott, Otwclra .trnsibilis L., Osmunda cinnamomea L., 

 Taxus canadensis Willd., Pinus Strobus L., etc. — are not here specially 

 noted, although species belonging to recently revised genera are 

 freely enumerated. In the following enumerations, the 110 species 

 of plants marked ** are new to the flora of Canada, while the addi- 

 tional ]2:l marked * are here recorded for the first time, apparently, 

 from Nova Scotia. The names of introduced species are in italics. 

 The International Rules of Botanical Nomenclature are followed.
