 scent of fennel, something of which remains in the dried speci- 

 mens. Stem erect, copiously leafy, panicled and corymbose at 

 the top, with numerous yellow^oujers, whose disk is small, the 

 rays short, gradually becoming revolute. Leaves variously pin- 

 natifidj remarkably dilated, rounded, and clasping, at their 

 base ; the segments toothed ; bluntish in the lower ones ; acute 

 in the upper, which gradually diminish into narrow linear brac- 

 teas. Calyx-scales fringed at the tips, not blackened and wither- 

 ed as in perhaps every other Senecio; but green or pale, at least 

 while in blossom > though they subsequently assume a withered 

 appearance. The outer ones are very small, but acute. Seeds 

 furrowedj slightly silky. Down roughish.
