PLANTS OF WHITE COUNTY—IV. 
Louis F. HEIMLICH. 
Heretofore the author has reported two hundred species of plants 
as growing wild in White County. The list below includes seventy 
additional species. Specimens of these species were collected in the 
vicinity of Reynolds and at several places along the Tippecanoe river 
north of Monticello. The collection dates were September 4, 5, and 6, 
and October 30, 1921. The nomenclature, for the most part, is that 
of Gray’s 7th edition New Manual of Botany. The authenticity of 
this list is vouched for by Mr. Charles C. Deam, of Bluffton, Indiana, 
who determined or verified every specimen. The numbers following the 
names refer to the specimen numbers in the author’s personal collec- 
tion. Brief notes are attached to a few species which seem to be of 
more than passing interest.

Pteris aquilina L. of present manuals. Nos. 558, 583.

ing along the Tippecanoe about two miles south of Buffalo. (Proc.
