Thysanocarpus pusillus, Hook. 



Common in parts of Vancouver Island bnt not found in 

 Brit. Columbia until 1890 when it was collected at Sproat 

 on the Columbia Eiver by Prof. Macoun. 



Claytoma cordifolia, "Wat. 



Found by Prof Macoun at an attitude of 5000 ft. on the 

 mountains near Warm Springs, Kootanie Lake, B. C. 

 New to Canada. 



Elatine Americana, Arn. 



In his catalogue of Canadian Plants Prof Macoun gives 

 but one station for this species- -Long Lake in Assinaboia. 

 During the past four years it has been found in widlj' 

 separated localities so that we may now safely say that 

 though of local occurrence it ranges in Canada from the 

 Atlantic to the Pacific. New stations for this species are 

 Tadousac Lake, Que. {Geo. G. Kennedy.) Hull, Que., and 

 Alberni, Vancouver Island. {John Macoun.) Port Sandfield, 

 Muskoka, Ont. (Dr. and Mm. Britton and Miss Timmerman.) 



Astragalus leucopsis, Torr, 



One clump of this plant was found by Prof Macoun near 

 Nanaimo. Van. Island in 1893. The scetl was doubtless 

 brought from California in ballast. 



Lldwigia alternifolia, L. 



Collected by Mr. Alex, Wherrj- of Windsor, Ont. in 

 1893. Mr. Wherry writes: — " It is found in low rich, 

 s\vamp3' ground generally meadows and postures, about 

 2 miles west of Sandwich, Ont. ; also within half mile of 

 Windsor, Ont. Quite common in these places but not met 

 with elsewhere by me." 



This species is credited to Canada in Torrey & Gray's 

 Floi-a and in Hooker's Flora but no localities are mentioned. 

 Both this and the next species are common in Michigan 

 and that they have been so recently found on the Canadian 

 side of the Detroit Eiver in a xegion that has been well
