spreading); the lower portion of the tube sharply 5-angled 

 with tuberculate ridges, differing sharply from the upper por- 

 tion: anthers caudate; filaments free and pubescent, arising 

 from the top of the angled base of the corolla tube: stigma 

 lobes short and obtuse, coalescent to maturity (but easily 

 separable), sharply deflcxed at the summit of the anther tube; 

 style with an indurated bulbous base which detaches readily 

 from the achene, which is linear and pubescent: pappus of num- 

 erous conspicuous puberulent slightly tawny bristles about as 

 long as the f^owers. 



Pereziopsis Doniiell-Suiithii, n. sp. — Probably woody be- 



low, 1.8 to ^.^'"high, densely woolly tomentose at least above: 

 leaves alternate, ample, pinnately divided, white with a dense 

 pannose tomentum beneath, more or lessfloccose woolly above 

 and becoming glabrate; terminal lobe ample, broadly deltoid, 

 irregularly lobed and dentate, conspicuously palmately veined, 

 20*'" long by 25*"" broad at the almost truncate base (dimen- 

 sions doubtless larger in the lower leaves); lateral lobes (us- 

 ually two) distant and very much smaller, the intervening 

 rhachis and petiole more or less wlnged: inflorescence an 

 ample naked corymb, with large terminal heads (about 3""™ 

 high) on the elongated branches, the ultimate divisfons brac- 

 teate: involucral scales narrowly linear and long acuminate, 

 more or less pubescent and purplish tinged, the inner 

 ones becoming as long as or even longer than the head: 

 flowers over 20™™ lons^. — Rio de Los Esclavos, Depart.
