 flavor resembling anise. Stem 2-3 feet high, purplish, pubescent when young (as well as 

 the petioles and peduncles), at length nearly smooth. Radical and lower cauline leaves on

 late and ciliate leaflets. Umbellets 3 - 6-flowcred. Involuccls of about 5 lanceolate and 

 ciliate leaflets. Flowers twice as large as in the following species. Fruit dark green or 

 blackish, much attenuated below, rather obtuse at the summit.
