CONTRIBUTIOXS FROM THE HERBARIUM OF THE 



GEOLOGICAL SURVEY. 



By James M. Macoux. 



Spergula sativa, Boenn. 



Common on Vancouver Island and the only species collected 

 there. Collected by Prof. John Macoun at Victoria in 1908, No. 

 78,504 and Ucluelet. No. 78,505, in 1909; Klondike River, 

 Yukon, No. 58,406. The specimens collected at Victoria in 

 1885 by Dr. Fletcher and recorded under S. arvensis, Macoun, 

 Cat. Can. Plants I, 499, are this species. In Rhodora, Vol. VII, 

 p. 151, Dr. Fernald writing of this species credits Dr. Fletcher 

 with having collected it at Ottawa in July, 1892, distributed as 

 5. arvensis, and in the last edition of Gray's Manual it is credited 

 to Ontario. While it is possible that Dr. Fletcher collected 5. 

 sativa at Ottawa none of the specimens from Ottawa in the 

 herbaria of the Central Experimental Farm or of the Geological 

 vSurvey are this species, and it is more than probable that in dis- 

 tributing specimens Dr. Fletcher mixed those collected on the 

 Pacific Coast with those collected at Ottawa, the former being 

 S. sativa. the latter S. arvensis. 



Lychnis coronaria, Desv. 



Common in the streets of Nanaimo, Vancouver Island in 

 July, 1908, Herb. No. 78,534. (John Macoun). Probably a 

 recent introduction as it was not seen at Nanaimo in 1887 or 

 1893 by Prof. Macoun, and is not recorded elsewhere in Canada 

 though found in se^eral places in Washington and the Eastern 

 States. 



Rosa alcea, Greene, Leaflets II: 63 



Collected at Moose Jaw, Sask., in 1892 by Wm. Spread- 

 borough and until recently in our herbarium without a name. 

 Will probably be found in other localities in the drv prairie 

 region. "Calyx-tube with not a few stout sharp spreading spines, 

 but sepals quite densely' glandular-prickly ; corolla large, the 

 petals obcordate." 



Hibiscus opulifolius, Greene, Leaflets II: 65. 



H. Moscheuius. Macoun, Cat. Can. PI. I: 87. 



This fine Hibiscus recently described by Dr. Greene and 

 represented in our herbarivim by specimens collected bv Prof. 

 John Macoun at Point Pelee, Lake Erie, in 1882, and at Leam- 

 ington, Ont., in 1892, is probably to be found in suitable situa- 

 tions from Point Pelee west to Windsor, Ont., as H. Moscheutus 

 has been recorded from the Detroit River.
