 usually broad umbels many-rayed. 



# Involucre, and involucels none.

 simply pinnate, with a tendency to be bipinnate in the lower pair of leaflets ; 

 leaflets 1 to 6 inches long, ovate to narrowly lanceolate, sharply and somewhat 

 unequally serrate, occasionally entire. Bot. King's Exp. 126. Wahsatch and

3. A. Dawsoni, Watson. Rather slender, 1 to 3 feet high : radical leaves 

 biternate, the lanceolate leaflets 1 or 2 inches long, sharply and finely serrate, 

 the terminal one sometimes deeply 3-cleft: cauline leaves (1 or 2 or none) 

 similar : umbel solitary, the conspicuous involucre of numerous foliaceous 

 lacerately toothed bracts nearly equalling the rays ; involucels similar. Proc.

 Angelica. 



1. A. Gmelini, DC. Stem a little downy at the summit, 1 to 3 feet

 the New England coast. 



15. CYMOPTERUS, Raf. 



Calyx-teeth prominent or often small or obsolete. Stylopodium depressed. 

 Fruit ovate or elliptical, obtuse or retuse. Low and often cespitose, with a 

 thickened root : leaves piunately and finely decompound, with small narrow

 # Flowers yellow. 



1. C. alpinus, Gray. Caudex cespitose: leaves pinnatisect ; pinnae 3 to 5, 

 approximate, 3 to 7-parted ; segments linear lanceolate, very entire, or the 

 lower 2 to 3-cleft : scape 2 to 4 inches high, bearing a subcapitate iimbel a little 

 longer than the leaves : involucels 5 to 7-parted ; segments equalling the 

 golden flowers : wings of the fruit somewhat erose ; oil-tubes 1 or 2 in the 

 intervals, 4 on the commissure. Am. Jour. Sci., n. xxxiii. 408. High alpine, 

 from Colorado to Mentana. 



2. 'C. terebinthinus, Torr. & Gray. Shortly caulescent, 6 to 18 inches
