Wart-Cress. 



Caltx equal at the base, spreading ; the sepals oval, cadu- 

 cous. Petals small, spatulate or linear, or abortive. Sta- 

 mens 6 and tetradynamous, or 4 (the shorter abortive), or 2, 

 one opposite each placenta, that is, occupying the position of 

 the longer pairs : filaments subulate : anthers didymous. 

 Ovary globular, and compressed contrary to the narrow par- 

 tition : style none : stigma entire. Ovule single in each 

 cell, pendulous from near its summit. 



Silicle strongly didymous, compressed contrary to the 

 very narrow partition, the closed valves or cells globular or 

 ovoid, indehiscent, nut-like, rugose-reticulated, or crested on 

 the hack, one-seeded. Seed suspended, obliquely obovate, 

 somewhat compressed contrary to the partition, smooth. 

 Cotyledons linear, thickish, bent transversely below the 

 middle, so that the upper part is incumberit against the as- 

 cending radicle. 



Herbs with annual or biennial roots ; the stems branched 

 from the base, diffuse or decumbent, the leaves incisely ser- 

 rate, or 1 — 2-pinnately parted. Racemes opposite the leaves, 

 often abbreviated, ebracteate : the flowers minute, white.
