302 GEOLOGICAL SURVEY OF CANADA. 



Hudson Strait. (R. Bell.) The specimens collected by Dr. Bell were 

 referred to C. pratensis in Part III., page 480. Since then, specimens 

 received from Greenland, have shown that these are the variety with 

 bright purple flowers. 



(130.) C. hirsuta, Linn., var. montana. 



This is a very distinct form and seems to be closely related to C. 

 sylvatica, but differs from that species in growing on mountains and in 

 wet places. It approaches C. oligosperma in having its leaflets almost 

 petioled. The specimens hitherto referred to 0. hirsuta var. sylvatica, 

 and collected in the Eocky and Selkirk mountains, belong here. Com- 

 mon on the wet slopes of Mount Queest and other high mountains in 

 the Gold Eange, near Griffin Lake, B.C., altitude 6000-7000 feet. 

 (Macoun.) Another form near the coast at Burrard Inlet has also been 

 referred to C. hirsuta, var. sylvatica, but it cannot be that species as it 

 differs in many minor points besides growing in wet ditches. 



(3070.) C. flexuosa, With.; Britton, Trans. N.Y. Acad., IX., 8. 

 (1889.) 



C. hirsuta, Linn., var. sylvatica, Gray, Man., ed. V., 67 (1867) ; Macoun, 

 Cat, L, 41. 



Dr. Britton says of this species : " So far as I have observed, its 

 habitat is on rocky banks in more or less shaded woodlands ; that of 

 G. hirsuta being either actually in the water or in very moist situations. 

 It appears to he a smaller plant than C. hirsuta, with a decidedly 

 flexuous stem, the leaves smaller and with narrower divisions." Our 

 knowledge of this species agrees exactly with that of Dr. Britton, 

 and we have no hesitation in changing the names as above. Our 

 specimens are from "dry rocks," close to Shannonville Station on the 

 G.T.E., Hastings Co., Ont., 1864; and Island Portage, Dawson Route 

 west of Lake Superior, 1872. (Macoun.) 



767. PLATYSPERMUM, Hook. 



(3071.) P. scapigerum, Hook. 



On open slopes, Mount Finlayson, Goldstream, Vancouver Island, 

 May 18th, 1887. (Macoun.)
