TETRADYNAMIA S1LIQU0SA. 
2. VlRGINICA. 
C. glabra, erecta ; 
foliis pinnatis, foliolis 
Ianceolatis, subauricu- 
latis ; siliquis stride 
eredis. 
Sp. pi. 3. p. 488. Mich. 2. p. 29. 
Glabrous, ered ; 
leaves pinnate, leaflets 
lanceolate, somewhat 
auriculate ; pods long, 
erect, straight. 
Pursh 2. p. 439. Nutt. 2. p 67. 
Root perennial? Stem 8 — 12 inches high, a little hairy. Leaves al- 
ternate, pinnate, leaflets somewhat lanceolate, generally angled on the un- 
der side, the upper ones larger. Flowers in terminal racemes, small. 
Corolla white, a little longer than the calyx. Pod terete, linear. 
Grows in the upper districts of Carolina. 
Flowers April — May. 
3. Pennsylvania. 
C. glabra, ramosa; 
foliis pinnatis, foliolis 
subrotundo-obtusis an- 
gulato-dentatis ; sili- 
quis angustis, erec- 
tis. 
Glabrous, branch- 
ing ; leaves pinnate, 
leaflets nearly round, 
obtuse, toothed and 
angled ; pods narrow, 
erect. 
Sp. pi. 3. p. 486. Pursh 2. p. 440. Nutt. 2. p. 67. 
Sisymbrium Nasturtium? Walt. p. 174. 
Root annual ? Stem erect, about a foot high, branching, angled and 
glabrous. Leaves pinnate or rather pinnatifid, glabrous, leaflets 4 — 6 
pair, obtuse, toothed, entire when very small. Flowers in terminal ra- 
cemes. Leaflets of the calyx linear lanceolate, glabrous, deciduous. Pe- 
tals twice as long as the calyx, obovate, white. Stamens a little longer 
than the germ. Style 0. Stigma obtuse. Pod about an inch long, te- 
rete and very slender. 
To the preceding species this bears much resemblance, it is distinguish- 
ed however, by its glabrous stem and leaves, by its larger and more dis- 
tinctly toothed leaflets, and by a pod longer and much more slender. The 
two species have probably been united by Michaux. 
Grows in wet lands. Very common in the tide swamps, resembling 
very much in flavour the garden cress, for which it is frequently used as a 
substitute. 
Flowers February — April.
