S. tanacetifolium. Walt. p. 174. 



Root perennial? Stem generally procumbent, 6 — 14 inches long, an- 

 gled and sprinkled with a transparent pubescence. Leaves pinnatifid, 

 glabrous, toothed and sinuate, the segments very gradually increasing in 

 size towards the summit. Flowers in simple racemes; racemes axillary, 

 opposite the leaves and terminal. Leaves of the Calyx lanceolate, a lit-\ 

 tie hairy, appressed. Petals nearly linear, tapering at base, scarcely as 

 long as the calyx, yellow. Tlie long Stamens just equal to the germ. 

 Anthers somewhat globose. Style very short. Stigma capitate. Pod 

 scarcely half an inch long, terete, slightly incurved, opening from the base^ 

 Very nearlj^ allied to the preceding species, from which it appears to dif- 

 fer by its procumbent stems and terete pod. 



Grows in damp soils. Common around Charleston and Beaufort* 



Flowers February — May.
