Arenaria or Stellaria, except that the capsule alone is that of Szlene 
rather; and I have named the genus Avodéz¢es in allusion to the ab- 
sence of those ear-like appendages of the petals seen in Sz/ene and 
in many another allied genus. 
The herbarium specimens of the Canadian Geological Survey 
have been of great service in this study, and about four of the 
species already described are known to me only as in that collec- 
tion, aud as belonging to the Canadian side only of the Interna- 
tional Boundary. That list is now raised to five by virtue of anew 
one more recently collected by Mr. Macoun, A. fzcfa, the first ac- 
count of whichis herein published. | With the description of this, 
I have thought it well to give the essential characters of all the 
Canadian species as I at present understand them: appending to 
such a key to the species, the notes of habitat furnished by the 
labels in the herbarium.
