Cardamines Sp., R. Br. in Ait. Kevv. ed. 2. 4. p. 101. 



Toothwort. Pepperroot. 



Calyx equal at the base, the sepals erect. Petals much 

 larger than the sepals, obovate, spreading, more or less un- 

 guiculate. Stamens and Pistil as in Cardamine. 



Siliq.ue lanceolate, compressed, subulate with the style, 

 elastically two-valved from the base ; the valves flat, nerve- 

 less ; placenta? not wing-margined : partition nerveless or 

 nearly so ; the areolation nearly quadrate and uniform (as in 

 Cardamine). Seeds several in each cell forming a single 

 row, round-oval, turgid, smooth, pendulous on broad and flat 

 free funiculi. Radicle ascending on the side remote from 

 the placenta : cotyledons accumbent, parallel with the par- 

 tition, very thick and fleshy, sometimes unequal. 



Herbs with a horizontal and fleshy toothed or moniliform- 

 tuberous rhizoma, which sends up in spring an erect and 

 simple flowering stem, bearing near the middle two or three 

 (or rarely more) verticillate or alternate 3 - 7-foliolate leaves 

 on naked petioles, and terminated by a corymbose raceme 

 of handsome white or rose-purple flowers. Radical leaves 

 sometimes wanting.
