 shrubby appearance, but most of the herb is annual. The stem 

 is set with thick and stiff bristles at the base. Leafets much 

 smaller than in the preceding, sharply and unequally serrate, 

 ending in a long point. Umbels several, on long peduncles. 

 Calyx teeth very short, subacute. Corolla greenish white with 

 a prominent rib on the upper side of each petal. Stamens as 

 long as the petals. Styles erect in the flower, but recurved and 

 tipt with black in the fruit. Woods, Cambridgeport. June.

 white flowers. Wet, boggy land. July, August.

Leaves spathulate-obovate, radical ; petioles naked ; 

 scape bearing a simple raceme.
