Calyx equal at the base ; the sepals spreading. Petals 

 equal, entire, spatulate or obovate. Stamens commonly 6 

 and slightly tetradynamous, rarely 4, or else only 2 (replac- 

 ing the longer pairs) : filaments subulate, toothless : an- 

 thers didymous or cordate. Ovary sessile on the recepta- 

 cle, globular, compressed contrary to the narrow partition, 

 two-celled, two-ovuled : style short or slender : stigma de- 

 pressed-capitate, usually entire. Ovule solitary in each cell, 

 pendulous from near the summit. 



Silicle much flattened contrary to the very narrow parti- 

 tion, oval or orbicular and nearly entire or emarginate at the 

 apex, or obcordate, two-celled, two-seeded, two-valved ; the 

 valves laterally compressed, navicular-carinate, wingless, or 

 often winged at the apex : areolae of the partition (in L. Tir- 

 ginicum and L. ruderale) quadrate or roundish, irregular. 

 Seeds pendulous from near the summit of the cell, com- 

 pressed contrary to the partition, wingless, sometimes sur- 

 rounded by a narrow margin. Cotyledons plane, oblong- 

 linear, parallel with the partition and incumbent on the
