SOME RECENT CHANGES IN THE FLORA OF 

 MONTREAL AND ADDITIONS THERETO. 



By Robert Campbell, M.A., D.D. 



Ornithogalum umbellatum L. — Found in marshy 

 little bay on north bank of St. Lawrence River, opposite 

 Verdun Hospital; and also near the Victoria Bridge, on 

 the* St. Lambert side of the St. Lawrence. August. 



Serapias Helleborine L. (Epipactis Viridiflora Reich-

 Mount Royal Park, Montreal, in 1894, a few specimens

 Since then it has multiplied so rapidly that thousands of

Aristolochia clematitis L. — A fairly large colony of

 It is maintaining itself in competition with grass and
