Hab. (i. Siedge Islaud, on the North- West coast of America. Nelson. Menzies. About Behring's Straits, 

 as far north as lat. 66° 13'. Chamisso. Cape Mulgrave and Kotzebue's Sound. Capt. BeecJiey's Collection. 

 Moist mountain prairies, in the Rocky Mountains, between lat. 52'^ and 56°. Drummond. — This is one of 

 the innumerable varieties mentioned by M. Seringe in De Candolle's ProdromuSy and which are figured by 

 Reichenbach as so many distinct species. Our plant from the Rocky Mountains is certainly identical with 

 that found by Nelson in Sledge Island, and is principally distinguished by the raceme of flowers being more 

 lax and flaccid than iu the common states of A. Napellus. A. Chamissonianum and A. semiyaleatum of 

 Reichenbach, do not seem to differ from this state of the plant, which in some points approaches closely to 

 A. biflorum of Fischer, in which, however, the upper part or bag of the nectary or cucullus is very different, 

 being large, round, very obtuse, and ^vithout a spur. 



2. A. nasutum; nectariis erectis, calcare arcuato, galea conica prona, rostro demisso, 

 racemis subpaniculatis, foliorum laciniis latiusculis. Spreng, — Fischer, MSS. Reicheiib,

Hab. Near the source of the Wallawallah River, a branch of the Columbia, which rises in the Blue 

 Mountains of North-West America. Douglas. — The figures above referred to are very characteristic of Mr. 

 Douglas's plant, especially the A. Fischeri of Reichenbach. This species is found in Kamtschatka, as well 

 as in Siberia and the South of Europe.

Hab. On the North-West coast of America. pursh.~l have seen no American specimen of this plant, 

 which is very common in Siberia, where its foetid smell has recommended it, as tiie name implies, for 

 driving away bugs. 



2. A, palmata; ovariis 12-15 in capitulum subrotundum collectis, racemis dichotome 

 subpaniculatis, foliis palmatifidis, carpellis siccis dehiscentibus. — De Cand, Syst. Veget v.

Hab. North-West coast of America. Menzies in Herb. nostr.^Stem two or three feet high, with few 

 and distant palmated and serrated leaves, upper ones sessile. Flowers almost corymbose. In habit and in 

 its simple leaves, very different from the other species of the genus, and Nuttall doubts if it may not prove 

 a distinct genus.
