Plant slender, sparingly and dichotomously branched, G to 18 

 inches high; radical leaves three-fourths to one inch long, obovate- 

 oblong, minutely ciliate-denticulate, somewhat enlai-ged and sub- 

 cordate at ])ase, with a short thickened clasping petiole and distinct 

 niid-ril); cauline bracts small, trifid, shortly acuminate, unilateral, 

 with a ((innate sheath round the sten); stijntate glands conspicuous 

 on the stems above the internodes; involucres on slender axillary and 

 terminal pedicels (three-fourths to two inches long,), expanding into 

 a short obscure tube conspicuously marked by longitudinal nerves, 

 which are prolonged ])eyond the irregular margin into a diverg- 

 ing crown of slender acicular awns (18 to 28), somewhat unequal, 

 about two lines in length, nearly twice the length of the involu- 

 cral tube; flowers 5 to 14, pedicellate, uneijually developed, the more 

 mature reaching nearly to the summit of the involucral awns, the 

 smaller usually staminate and abortive, with bracteoles of two 

 kinds, (me linear-spatulate, pubescent and ciliate. the other linear, 

 about as long as the pedicels ; perianth 6-cleft nearly to the base, 

 divisions ovate, pubescent on the outside, smooth within; stamens 

 9, inserted at the base; akene lenticular, obtusely pointed, the
