The smaller 



Botrychium simplex seems to be a plant liable to much variation in regard to size. 

 pecimen here figured, which we received from our zealous friend Dr. Torrey, seems to be the 



which gave rise to the specific name and charact 



Silliman s Journal : — but we have received a 



plant through the kindness of Mr. Lambert, gathered by Pursh in Canada, which we 



by 



means distinguish from that just mentioned, except that it is twice the size, has the frond decidedly 

 pinnatifid, and the segments much cut. This is the larger specimen here represented. Both va- 

 rieties are abundantly distinguished from any species with which we are acquainted.
