 T have cultivatcd this from seeds sent by Mr. Wright from the Rio Grande ; and 

 it proved to be a difFusely branched perennial, or at least to continue two or three 

 ycars, although the root in indigenous specimens seems to be that of an annual. 

 Ecsides the pappus, which so well distinguishes it, the stems are more slender and 

 elongated than in any of the foregoing, sometimes a foot long, the branches termi- 

 nated by ncarly nakcd peduncles of three or four inches in length ; and the lobes of 

 the leaves (cincrcous-pubcrulent in the wild plant) are short and subulate, only one 

 or two lincs in length. Involucre three lines long, smooth, subtended by three or 

 four small and subulate appressed bracts. Eays oblong. Palete of the pappus all 

 alike, except that a few are rather smaller, cleft into one or sometimes two capillary 

 aAvns and two short lateral setce or setaceous teeth, and occasionally showing a pair 

 of rainutc additional teeth. Sometimes the principal lateral lobes are merely seta- 

 ceous or^subulate teeth ; oftcn one or both of them are as slender as the proper

it came from Northern Mexico, instead of Chili, and that it is identical with the
