New Alpine Plants, 



105 



trapezoid, trlfid, or the upper ones cuneate, all in front deeply 

 and acutely toothed, often laciniated ; leaves of the stem 

 from one to three, pinnatisected ; rays of the umbel 4-5, 

 unequal, furrowed, glabrous ; bracts 1-3, bracteoles several, 

 both setaceous ; fruit glabrous, truncate-ovate, with very 

 prominent ribs. 



On the gravelly borders of alpine rivulets and springs in 

 the Munyang Mountains (5-6000'). 



The want of ripe fruit of this plant leaves some doubt 

 about its true generic position. It is unquestionably allied 

 to Seseli Harveyanum.
