A. leptoceras we also find to have been given previously to 

 another, and Siberian, species. We have now reason to know 

 that, like our own A. vulgaris, the flowers are liable to vary in 

 colour, and unquestionably the present variety is far more worthy 

 a place in our gardens than that given before. It was this va- 

 riety which led James to say, " It forms a splendid addition to 

 the Flora of the United States ;" and our collector, Mr. Burke, 

 who detected it about Fort Hall, remarks : " We have here a 

 most beautiful Columbine, which I have never found elsewhere, 

 growing at the foot of a hill in rich loamy soil in great abund- 

 ance ; the flowers very large, beautifully white, variously tinged 

 above with light blue. In my opinion it is not only the Queen of 

 Columbines, but the most beautiful of all herbaceous plants."
