botanized may go to show that they are extending their 

 limits. 



Ludwigia polycarpa, Short & Peter. 

 Found by Prof. Macoun in 1891, growing in ditches and 

 along the railway track near Amherstburg, Ont. 



(tRindelia squarrosa, Duval. 



This common prairie plant has become naturalized in the 

 vicinity of Skead's Mills near Ottawa, Ont., where it was 

 found by Mr. Wm. Scott in 1890, the seed having been 

 doubtless brought from the west either in grain or attached 

 to cars of the Canadian Pacific Railway. 



Aplopappus Lyallii, Gray. 



This plant is probably to be found on most of the higher 

 mountains in British Columbia but was overlooked until 



1890, when it was collected in the Gold Range by Mr. Jas. 

 McEvoy and by the writer on a high mountain near 

 Kicking Horse Lake in the Rocky Mountains. 



That it was not collected before, is I believe to be 

 attributed to its close resemblance to a form of Solidago 

 multiradiata var. scopulorum, Gray, Common on all the 

 mountains in British Columbia with which it was growing 

 when found by me. With it Aplopappus Brandegei also 

 grew and it was while collecting specimens of this plant 

 that I noticed what appeared to be two forms of the 

 Solidago referred to, but one of which proved on examin- 

 ation to be A. Lyallii. 



This species was again found by Prof. Macoun in August, 



1891, in abundance on the mountains around Lake Agnes, 

 near Laggan, Rocky Mountains. 



Aster stenomeres, Gray. 



Until 1890 confined, so far as known, to Idaho and 

 Montana. In that year young plants were found by Prof. 

 Macoun on a mountain near the Columbia River at Sproat, 

 B. C, they were brought to camp, placed in water and at 

 the end of a week were in full bloom.
