CERTAIN CANADIAN VIOLETS. 



By Edw. L. Greene. 



In a recent issue of Pittonia* I published a number of Cana- 

 dian violets of that caulescent group to which the following belong,

 densely bearded, the hairs narrowed upwards rather than clavel-

 (now called F. Lahradoricd) as an albino variation ; and, albino
