Calyx of 4 herbaceous or purplish spreading sepals, im- 

 bricated in aestivation, deciduous. Petals hypogynous, 

 nearly equal, somewhat turned to the upper side, obcordate 

 or obovate and emarginate, on slender or filiform claws, im- 

 bricated in aestivation, deciduous. Torus inconspicuous, 

 convex, produced on the upper side into a thickened gland. 

 Stamens 9 to 32 (usually 12 to 24) : filaments filiform or 

 capillary, declined (purple), inserted on the depressed torus, 

 the anterior ones usually shorter : anthers oval, fixed by 

 the base ; the cells opening introrsely by a longitudinal line. 

 Ovary oblong, glandular-viscid, sessile or nearly so, one- 

 celled, with two parietal placentae : style filiform : stigma 

 depressed-capitate. Ovules very numerous, in two series 

 upon each placenta, horizontal, amphitropous. 



Capsule silique-shaped, linear-oblong, turgid, nearly terete, 

 sessile or very short-stipitate, two-valved; the reticulated- 

 veiny valves separating from the filiform placentae ; the style 

 deciduous. Seeds numerous, reniform-conduplicate, exal- 

 buminous. Embryo conformed to the seed : cotyledons 

 incumbently incurved upon the ascending radicle. 



Herbs annual, viscid-glandular with a heavy odor, leafy ;
