 usually acute, sessile, 1-2 cm. long : peduncle short : heads rather 

 small, 6-7 mm. high ; involucral bracts linear, acuminate, not 

 more pubescent than other parts of the plant, in about two series : 

 rays pale violet, 20 to 25 in number, 1 cm. long: pappus sim-

 tal caudexes, the pistillate plants 6-10 cm. tall: the staminate 

 somewhat shorter : radical leaves lanceolate-spatulate, 2-4 cm. 

 lon g» 3-5 mm. wide, in the widest part, mostly acute, appressed 

 pubescent on each side : cauline 2—4, narower and more acute, the 

 uppermost equaling or exceeding the head : pistillate heads ob- 

 long, 12-13 mm. long, 6 mm. wide, its bracts closely imbricate, 

 the outer ovate to ovate-oblong, acuminate, Ianate on the exposed 

 parts, hyaline tinged with pale brown and pink, the inner paler,
