Hab. Arctic America ! ; Kotzebue's Sound ! /3. in hem- 

 lock woods of Vermont and New Hampshire, Pursh ; on 

 Mount Washington, New Hampshire, Bigelow and Dr. Bar- 

 rattl — After a most careful examination, we find but two stig- 

 mas in all the flowers of our fine suite of specimens of C. 

 Washingtoniana., collected by Dr. Barratt, on whose specimens 

 the species Avas founded. The fruit seems to us rather obtuse 

 than acute ; and the scales, although somewhat variable, are 

 mostly as obtuse as in our European forms of C. saxadlis. 

 We do not hesitate, therefore, to consider the plant a variety 

 of C. saxatiUs. This view is wholly confirmed by an exami- 

 nation of our numerous specimens of that species from the 

 North of Europe : those from Norway, Silesia, &c., so closely 

 resemble the plant from Mount Washington that they can 

 scarcely be distinguished ; while, on the other hand, specimens 

 from Lapland, &c., which differ in being somewhat smaller, 

 in their shorter and more clustered spikes and dark-coloured 

 fruit, are in all respects similar to those fi-om Arctic America. 

 These last have much of the aspect, of C. nigra. It cannot 

 now be doubted that our /3 of this species was really seen by 

 Pursh, and correctly referred to C. saxadlis ; and it is highly 

 probable that it will hereafter be found in other localities in 

 the northern portion of New England besides Mount Wash- 

 ington.
