5. Summary 



In the present paper, 349 bryophytes are recorded as having been collected 

 in Cape Breton. ^ Of this number, 93 species are liverworts, 256 are mosses. Of 

 the total number, 170 species (51 liverworts, 119 mosses) have been recorded 

 from Nova Scotia also, while' 179 species (41 liverworts, 138 mosses) are ac- 

 credited only to Cape Breton. On the other hand, 50 of the species listed from 

 Nova Scotia (9 liverworts, 41 mosses) have yet to be recorded from Cape Breton. 

 Considering the province of Nova Scotia as a whole, its bryophyte flora, as summed 

 up in the present paper, includes 399 species: 102 liverworts and 297 mosses.

1 Common in Cape Breton also, but no specimens preserved. 



2The figures here given do not include species queried [?] in the preceding lists. For various 

 reasons it seems not unlikely that a few others ot the mosses listed by Macoun should also be ex- 

 cluded.
