borcaleYxx^?,, Herb. Norm. 16: 85. 



This species has, as far as I know, been collected only at one 

 station in North x\merica, viz., on the Island of Unalaschka. It is 

 a very rare plant, nearest related to B. Lunaria, but differs in the 

 short, triangular sterile portion, which is borne very high up, close to 

 the fertile portion.

(name). 



It is nearest related to B. obliqnum Willd. (^B. tcrnatum of Amer- 

 ican authors) of the East, but is a much stouter plant v/ith short- 

 petioled very fleshy leaves. It seems to be confined to the formations
