LEGUMINOSAE (PULSE FAMILY) 



247 



and four to eight pairs of oblong 

 leaflets, slightly notched at their 

 tips and with midrib project- 

 ing as a fine, bristly point. Ex- 

 tending from between the terminal 

 pair of leaflets is a long forked 

 tendril. Flowers on short axillary 

 peduncles, usually in pairs, nearly 

 an inch long and rather showy, the 

 corolla being reddish purple or 

 sometimes rosy pink, the stand- 

 ard long obovate and notched at 

 the top, the wings adherent to the 

 curved keel. Pods slender, two to 

 three inches long, hairy when 

 green but becoming smooth, and 

 slightly constricted between the 

 small globular seeds as they ripen. 



Means of control 



Prevent the development of seeds 

 by early and close cutting. In 

 grain fields, many of the young 

 seedlings may be raked out with a weeding harrow when the crop is 

 but a few inches tall. Or, later, but while still in the young and hairy 

 stage, the weed may be destroyed by the use of chemical sprays.
