Society ; and, in addition, we have consulted the herbaria of Mt. Hol- 
yoke and Amherst Colleges, and the Knowlton herbariume of the 
Massachusetts Agricultural College. The mosses, liverworts, lichens, 
fungi and. Characeae have been purposely omitted from this list. 
The list of lichens in Prof. Tuckerman’s catalogue is one of the most 
complete and authentic published, but the list of fungi, Characeae, 
etc., contributed by Mr. Frost is of little value as it stands today, since 
much progress has been made in the study of these groups since his 
time. 
This list would possess much less value were it not for the work of 
my predecessors, and frequent reference has been made to Pres. Ed- 
ward Hitchcock’, Prof. Edward Tuckerman’, Prof. H. G. Jesup?, Col. 
W.S. Clark?, Dr. N. A. Cobb and others, who have contributed to 
the previous lists of this region. 
I have endeavored to differentiate between indigenous (native), nat- 
uralized, and adventive species (introduced but not permanently estab- 
lished), by putting the naturalized species in capitals and the adven- 
tive in italics, although there may be some errors in judgment as to 
which are adventive and which naturalized in our range. 
The nomenclature and arrangement of families, etc., follows Gray’s 
Manual, seventh edition, although we have in some instances referred 
to Britton & Brown’s North American Flora, and Prof. L. H. Bailey’s 
Cyclopedia of American Horticulture. 
This list contains in all 1190 native and 303 naturalized and adven- 
tive species, a total of 1493.
