NOTES ON THE FLORA OF NORTHAMPTON 
COUNTY, PENNSYLVANIA 
By EUGENE А. RAU 
Having for a number of years studied the flora in the vicinity 
of Bethlehem and having made quite a large sized herbarium it 
was an agreeable surprise for me to notice Mr. King's Flora of 
Northampton Co., Pa., recently published in ТоккЕҮА. In 
examining the list, however, I detected the omission of a number 
of plants which I had found at various times, and by reference 
to my herbarium desire to record the addition of the following 
together with the addition of a number of habitats. 
Apparently much work still remains to be done in recording 
the flora in all parts of the county and designating the ranges of 
the various species. A thorough search will doubtless necessitate 
many additions to the list and thus relieve it of the too local 
character which it now bears.
