(531.) O. splendens, Dougl. From Morley to Canmore, in the 

 Bow Eiver valley. Lat. 51. (Macoun.) 

 Page 117. 



(532.) O. deflexa, DC. Both at low and high altitudes from 

 Morley to Canmore, Bow Eiver valley. Lat. 51. (Macoun.) 



(2126.) O. viscida, Nutt. 



0. campestris, var. viscida, Watson, Part I., 116. 



Very fine and abundant along the Bow Eiver from the Blackfoot 

 Crossing, westward up the valley and through the Eocky Mountains 

 to Donald in the Columbia valley, Lat. 51. (Macoun.) 



(2127.) O. leucantha, Pers. 



0. borealis, DC., Hook. Fl. I., 145, belongs here rather than to 0. <m- 

 pestris, as in Part I., 116. 



Cape Thompson, arctic sea-coast. (J. Muir.) Port Burwell, Cape 

 Chudleigh ; also, Cape Prince of Wales and the Eskimo village of 

 Hyla, Hudson Strait. (R. Bell.) Specimens very distinct; stipules 

 chestnut colored and conspicuous. 



(2128.) O. monticola, Gray. 



0. Lamberli, Pursh, Part I., 116, in part. 

 0. campestris, DC., Part I., 116, in part. 



Souris Plain, around Moose Mountain, N.W.T. (J. M. Macoun.) 

 Eat Creek, Manitoba, and westward across the prairie ; much more 

 common than O.Lamberti, and distinguished from it by its lax flowered 

 spikes, less downy leaves and darker haired calyx. It extends from 

 Morley to the " Gap," in the Bow Eiver valley. It is the true prairie 

 form. (Macoun.) 



(2129.) O. Mertensiana, Turcz. Cape Lisburne, arctic coast 

 of Alaska. (Gray.)

(533.) H. boreale, Nutt. Abundant on the upper St. John, rarer 

 on the Tobique, Eel and other tributaries, Edmundston, 1ST.B. (Hay.) 

 Island of Anticosti. (St. Cyr.) Eather common at Morley and west- 

 ward to Canmore in the Bow Eiver valley, Lat. 51. (Macoun.) 



Var. albiflorum, Macoun. This fine plant is closely related to 

 If. boreale, but is certainly distinct. All three forms grow together in 

 the Bow Eiver valley, but the habit of each is quite distinct from the 

 other. This form is peculiar to the foot-hills and drier mountain
