CRUCIFERAE (MUSTARD FAMILY) 



177 



Lower leaves pinnatifid, spatulate in outline, with terminal lobe 

 large and lateral lobes very small ; stem-leaves merely toothed, not 

 lobed, the upper ones becoming lance-shaped and often entire. 

 Flowers white, very small, on elongating racemes that are finally 

 six or eight inches in length, closely set with small, round, flattened, 

 two-celled silicles, notched at the outer edge and each containing 

 two reddish yellow seeds. Birds are very fond of these seeds and 

 dispose of large quantities ; they are a common impurity among 

 clover seeds. 

 Means of control the same as for Shepherd's Purse. (Fig. 121.)
