CRUCIFER^E 



THE PREFERRED HABITAT: low grounds and roadsides. 



THE PLANT: erect, one foot to two feet high; the stems 

 tufted. 



THE LEAVES: scattered; at least the lower pinnatifid, the 

 end division much larger than the lateral, all oval or obo- 

 vate; upper leaves toothed or pinnatifid, sessile or nearly 

 so or sometimes clasping. 



THE FLOWERS: four petals slightly in the form of a cross; 

 six stamens of which four are prominent. 



THE FRUIT: a pod. 



This, the prettiest and the daintiest of the mustards 

 described here, is characterized by the pleasing contrast 

 of colouring of the spikes of small yellow flowers with 

 the dark green and shining leaves. The flowers have the 

 four petals as is seemly in this Family and the leaves are 

 properly cut. 



Twenty two other members of the Mustard Family 

 have been reported.
