No botanist has been known to visit Nantucket for spe- 

 cial collection of its mosses and liverworts, but the few 

 species of the following list have been picked up from time 

 to time and submitted to competent specialists for the names. 

 The island does not seem to be rich in these orders, and the 

 specimens found are, in many cases, unfruited, making a sure 

 identification difficult, still additions to the present list can 

 certainly be made.
