In gardens and cultivated fields, a common weed. 



Annual. Julijy August. 



Root tapering, whitish. Herb erect, of a dark lurid green, fetid and 

 reckoned dangerous. Stem round, striated, leafy, often purplish, 

 a foot high. Leaves with short sheathing /oo^s^a/A:^, all doubly 

 pinnate, with decurrent, pinnatifid leaflets. Umbels stalked, ter-

 their long, narrow, pendulous partial bracteas, and the want of 

 general ones. Fl. pure white, rarely partially abortive. Fruit 

 pale brown.
