 readily convinced that all the species from North America are far 

 from being well known and that much remains to be done in 

 order to make them completely clear * * * but the hint is 

 given ; we are persuaded that our American confreres will make 

 rapid progress in the knowledge of their rose flora/' A. H.

 known from these little visited islands. 



In the same pages is begun a supplementary ermmeration of
