Flora of Cacouna, P. Q. 457 



Taxus canadensis, Willd. (American Yew. Ground 

 Hemlock.) 



Somewhat abundant on Cacouna Island towards the 

 summit. Also along the base of the cliffs near the 

 Landing. Fruit. 



Microstylis monophyllos, Lindl. (Adder's Mouth.) 

 A few plants in the moist woods of Cacouna Island.

 Spiranthes romanzoffiana, Cham. (Ladies Tresses.) 

 Found very abundantly in low ground anywhere ; also
