A stronger growing plant than C. pinnatilobata, of which it has nearly the foliage, 
and from which it chiefly differs in its copious pubescence ; in this latter character 
it agrees with C. pinnatifida. Some of Drege’s distributed specimens of var. 8. 
belong to C. pinnatilobata. 
5. C. pinnatifida (Less. Syn. 204); herbaceous, all parts densely 
clothed with spreading, white hairs; cauline leaves pinnate-parted, the 
lobes lanceolate-linear, obtuse, spreading, entire or few toothed ; heads 
2-3 at the ends of the branches; invol.-scales hairy ; achenes downy.

lete, and sometimes there is an additional pair, higher up on the petiole. Leaves 
1-2 in. long, $-1 in. broad, Axils obtuse ; branches spreading, curved upwards.
