402 Canadian Record of Science. 



This has been its history in several localities in Ontario — 

 August. 



Helianthus strumosus, L. — Sunflower — Mount Koyal 

 Park — August. 



G-alinsoga parviflora, Cav. — For the last three years 

 I have observed a numerous colony of this plant on the 

 McGill College grounds, in front of the new Workman 

 buildings, on a piece of recently made-up ground. This is 

 the first time the plant is reported from Canada, although 

 in the 6th edition of Gray, p. 286, it is said to occupy 

 "waste places, especially eastward." It is a modest plant, 

 about nine inches high, its rays inconspicuous, so that it is 

 not likely to attract the attention of any but a practised 

 eye. There is a risk that the plant will disappear, however, 

 as several feet more of earth has been filled in over where 

 it grew, unless it has managed to extend itself beyond the 

 sidewalk, into the grass, among which it maintained a 

 successful struggle. I secured several specimens of it in 

 successive years. — August.
