Root perennial ? Stem 8 — 1 2 inches high, a little hairy. Leaves zU 

 ternate, pinnate, leaflets somewhat lanceolatej generally angled on the m- 

 der side, the upper ones larger. Flowers in terminal racemes, sraalj, 

 Corolla white, a little longer than the calyx. Pod terete, linear. 



Grows in the upper districts of Carolina. 



Flowers April — May.

 Sisymbrium Nasturtium ? Walt. p. 174. 



Root annual ? Stem erect, about a foot high, branching, angled and 

 ^abrous. Leaves pinnate or rather pinnatifid, glabrous, leaflets 4—6 

 pair, obtusej toothed, entire when very small. Flowers in terminal ra- 

 cemes. Leaflets of the calyx hnear lanceolate, glabrous, deciduous. F^" 

 tals twice as long as the calyx, obovate, white. Stamens a little longer 

 than the germ. Sti/le 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. Th^ 

 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 » 



substitute. 



Flowers February — April.
