Means of control

 stalks before any fruit has matured. In order to destroy the peren- 

 nial roots it is necessary to put the land under cultivation. 



SANICLE OR BLACK SNAKEROOT 



Sanicula canadensis, L. 



Native. Perennial. Propagates by seeds. 



Time of bloom: June to August. 



Seed-time: August to October. 



Range: Massachusetts to Nebraska, southward to Florida and 



Texas. 

 Habitat : Shrubby upland pastures, thickets, open woods. 



Sanicle is a shade lover and would 

 hardly be included in this weed list 

 were it not that its hooked and prickly 

 carpels are so detrimental to the fleeces 

 of sheep. The plant has bitter juices 

 which protect it from their nibbling 

 jaws and it is left to reproduce itself 

 unharmed. 



Stem rather stout, eighteen inches 

 to three feet tall, erect, round, grooved, 

 smooth, with forking, leafy branches. 

 Leaves palmately compound, three- to 

 five-parted, the segments narrowly obo- 

 vate to lance-shaped, smooth, sharply 

 and irregularly toothed, often cut- 

 lobed ; those at the base have long 

 petioles but the stem leaves become 

 smaller and nearly sessile as they near 

 the top; involucral leaves small and 

 lance-shaped. Flowers greenish white, 

 with perfect and staminate flowers in- 

 termixed in small, compact, globular 

 umbels, not much more than a half- FIG 

 inch broad. In this species the styles
