Stem 1 to 3 feel high, branched from about the middle, with 
the branches more spreading and longer in proportion than in 
S. Jacobsea ; the leaves less deeply divided, less undulated, and the 
lower one with a much larger terminal lobe. Ant bodes fewer, in a 
much more lax and irregular corymb, larger, 1 to 1^ inch across; 
hut the most striking difference between the two species is that the 
ichenes are glabrous, or sometimes with a very few hairs between 
the shallow ridges in S. aquaticus, even in the disk-florets, while in 
!>. Jacobaea the latter are hairy. Leaves generally purple below. 
A form between the extremes of vars. a and is the most 
common.

Rootstock creeping, w 7 itb elongated stolons. Stem erect, gla- 
brous, simple, except at the extreme apex, where it is corymbosely 
branched. Leaves firm, sessile, elliptical or oblong- elliptical, 
sub-semi-amplexicaul ; lowest ones oblanceolate- elliptical, sub- 
petiolate ; all finely and irregularly serrate with incurved teeth, 
glabrous or nearly so on both sides. Corymbs solitary, or several 
combined into a rather irregular compound corymb. Anthodes 
numerous, erect. Pericline cylindric - hemispherical, pubcrulent ; 
outer phyllaries [• to G, two-thirds the length of the inner, linear.
