Hudson Sti-ait. (B. 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. Tt approaches C. oligosperma in having its leaflets almost 

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

 and collected in the Eoeky and Selkiik mountains, belong here. Com- 

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

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

 (Macoun.) Another form near the coa.st at Biirmid Inlet has also been 

 referred to 0. hirsuta, var. sylvatica, but it cannot be that species as it 

 differs in manj- minor points besides growing in wet ditches. 



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

 (1889.) 



C. hirstita, Linn., var. »ylmtica, Graj', Man., ed. V., 67 (1867) ; Macoun, 

 Cat., I., 41. 



Dr. Bi-itton says of this species : — " So far as I have observed, its 

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

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

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

 iiesiious 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 Eoute 

 west of Lake Superior, 1872. (Macoun.)
