clined, on that account, and because it is "fruticose," to con- 

 sider the Molina linearis of Ruiz and Pavon, rather than B. 

 PingrcRa^ (to which De Candolle refers it) to be the same 

 with this plant. We are, however, sure that it is the B. pani- 

 ciilata of De Candolle, and we think it safer to preserve that 

 name to it. On the closest examination, indeed, we do not 

 find the leaves to be ever serrated, or otherwise tlian entire : 

 they are very constantly linear or linear-lanceolate, of a thick- 

 ish and fleshy character, when dry, at least, carinated at the 

 back, channelled above, and a depressed line will be seen on 

 each side the indistinct costa in the broader ones, indicating 

 a 3-nerved leaf. The flowers or capitula are copious on the 

 very numerous erect branchlets, thus forming a leafy pa- 

 nicle upon every large branch.

 are too narrow to be considered as approaching to oblong, 

 the teeth are large and spreading, the involucres moderately 

 large, in the female plants almost cylindrical.
