Thalictrum dioicum x purpurascens. 



Specimens from Eel River, Restigouche, N.B., (R. Chal- 

 mers.) with leaves glandular and fruit intermediate have 

 been referred here by Dr. Trelease. 



Note — All the specimens of Thalictrum referred to above 

 have been examined by Dr. Wm. Trelease and our deter-

Anemone deltoidea, Dougl. 



Specimens collected in the Coast Range by Dr. G. M. 

 Dawson, were referred here by Prof. Macoun, (Cat. Can. 

 Plants p. 13.) A recent examination of these specimens 

 shews them to be A. Michardsoni. A. deltoidea has not been 

 found in Canada. 



Anemone hepatica, L. 



A few leaves collected by Dr. Robt. Bell on the Upper 

 Savage Islands, Hudson Straits, (Macoun, Cat. Can. Plants, 

 p. 478), prove to be the root-leaves of Saxifraga cernua and 

 not A. Hepatica.
