Ilntrobuction. 



By the generosity of Mrs. Fanny D. Bergen, of Cambridge, Mass., 

 the lists of folk-names for many flowers have been greatly enriched. 

 Recognition is due also to Dr. B. F. Robinson, and to his assistants of 

 the Harvard Herbarium, for very kind aid in the botanical classification 

 of specimens.
