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.)
