liigli, somewhat branchiufi; above, yhihrous or nearly so and soniewliat 

 glaucotis, terminated hy lonj? (10 to l^^.f/'") naked (or minnteiy bracteate) 

 peduncleswhich arc enlarj^ed beneath the large solitary lieads: leaves narrowly 

 linear or almost liliforin, 2.5 to f)"" lon<f, entire or pinnatifid with two or three 

 linear lobes: bead about 2.5"" broad; the involucral bracts (ddon^, obtuse, 

 glabrous, dark-veined, loosely imbricated in about three sticecssivily shorter 

 rows: rays ten to fifteen, narrowly linear, 12 to 18""" long: disk-lh)wer8 with 

 ratlier deeply lobed corolla : ak(nuss lO-striate, the striiu rngulosc and 

 sparsely pubescent, about :?""" long: pappus of numerous scabrous rufous 

 bristles: sty]e-tit)s with short ovate appendages.— Santa Maria ({Cameron 

 county). This species is apparently related to A. itiniilohuf^ Crav, but the 

 ahnost smooth akenes and very slun-t style appendages, as well as the sn;ootli 

 oblong, obtuse and une(inal involucral bracts, and leaf characttirs, serve well 

 to distinguish it.

 Mountains (Foley eounty). In foliage and akem^s nnich resembling A. 

 ycalleiii, but in size of heads, and character of involucral scales, rays, and 

 liappus, very dilferent. With the present grouping of spi^cies these diil'erences 

 refer the two species to dilferent sections of the genus.
