3. Walteri E. 
S. ramosissimum, 
procumbens ; foliis 
pinnatifidis, laciniis 
obtusis, sinuato-denta 
tis, supremis confluen- 
tibus ; siliqnis brevi- 
bus, sub erectis. E. 
S. tanacetifolium. Walt. p. 174. 
Much branched, 
procumbent ; leaves 
pinnatifid ; segments 
obtuse, sinuate-den- 
tate, the upper conflu- 
ent ; pods short, gen- 
erally erect. 
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. Floivers in simple racemes; racemes axillary, 
opposite the leaves and terminal. Leaves of the Calyx lanceolate, a lit- 
tle hairy, appressed. Petals nearly linear, tapering at base, scarcely as 
long as the calyx, yellow. The 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 nearly 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. 
4. Amfhibium. 
S. siliquis declina- 
tis oblongo ovatis ; fo- 
liis oblongo lanceola 
tis pinnatifidisve, ser- 
ratis; petalis calyce 
longioribus. 
Pods declining, ob- 
long ovate ; leaves 
oblong, lanceolate, 
sometimes deeply ser- 
rate and pinnatifid ; 
petals longer than the 
calyx.

Sisymbrium indicum. 
Root perennial ? Stem erect, about a foot high, branching, angled, 
glabrous. Leaves lanceolate, acute, deeply toothed, the lower ones pin- 
natifid, sinuate, and tapering at base. Flowers in terminal racemes. 
Leaves of the Calyx oval, appressed, deciduous, a little hairy near the
