NOTES ON THE FLORA OF ONTARIO.

Notes on the Species of Ranunculace^e occurring in Ontario 



or Western Quebec. 



Within the above limits we have fifteen genera and forty-four 

 species. Many of these occur under diverse conditions and in peculiar 

 habitats and are seldom observed except by botanical collectors. It is 

 the purpose of these notes to enumerate them all and in this way enable 

 members of the Club and others to look out for them when opportunity 

 serves. 



The genus Clematis has with us two representatives which are 

 very unlike in appearance and habit. The more common species is 

 C. Virginiana which grows along all our rivers and brooks and climbs 

 over alders and other bushes where its fruits of long-tailed achenes 

 make it a prominent object in the autumn. In July and August its 

 greenish white flowers are quite attractive and when carefully examined 

 it will be found that the staminate one is the more beautiful as the 

 filaments of the numerous stamens really make up the flowers. 



The Atragene, (C verticillaris) is rather rare in the settled parts of 

 the province but on the rocky slopes of the Laurentide hills it is not 

 uncommon and when seen is not easily forgotten, its violet sepals, from 

 one to two inches long, being seen early in the season when flowers are 

 more attractive than they are later. Kingsmere mountain is the nearest 

 station to Ottawa. 



The genus Anemone is represented by six species though two of 

 them do not occur in the settled parts of the area under consideration but 

 have their homes along Lake Superior and northward.
