plant (Fig. 44), usually i to 2 feet, although it may attain 

 3 feet in height. The leaves are comparatively few, and 

 finely divided ; the rootstock or tuber, which lies deeply 



beneath the surface of 

 the ground, is rough, 

 brown or purplish, often 

 half the size of a walnut ; 

 the terminal umbels of 

 small, white flowers ap-

 by roadsides, and en-
