260. H. Maximiliani, Schrad. Prairies, margin of woods 

 and deserted fields ; common from Houston to the Colorado, 

 flowering in October and November. Stems four to seven 

 feet high, much branched. Well distinguished by the great 

 and equable cinereous roughness of the stem, and of both 

 surfaces of the lanceolate attenuate-acuminate leaves. It 

 becomes, however, much less rough in cultivation. 



261. H. Maximiliani, (3 asperrimus. A variety of the 

 last, as we take it to be, with a simple stem, two to three and 

 and a half feet high, bearing solitary or few heads. Prairies 

 between the Brazos and the Colorado, forming large patches. 

 October. 



262. H. grosse-serratus, Martens : the same form, with 

 the large leaves silvery-tomentose beneath, which was col- 

 lected in Texas by Drummond, and which, as it best deserves 

 the specific name, is assumed in Torr. &f Gr. Fl. I. c. as the 

 type of this variable species. Banks of rivulets and margin of 

 woods. August — October. 



263. H. grosse-serratus, (3 Toit. &f Gr. Fl. I. c. A 

 less canescent variety, with the stem, although somewhat 

 glaucous, slightly scabrous throughout. Prairies, &c, with 

 H. Maximiliani. 



264. Cosmidium filifolium, Tor?', fy Gr. Fl. II. p. 350. 

 Prairies west of the Brazos. May — June. This is really a 

 perennial, and proves quite ornamental in cultivation. It 

 extends as far north as the south-western borders of Missouri. 



265. Dysodia tagetoides, Torr. &/• Gr. Fl. II. p. 361. Wet 

 prairies, and on sandstone hills of Mill-creek. August. This 

 is also a perennial. The dots of the leaves are orange-yellow. 



266. Palafoxia Hookeriana, Torr. fy Gr. I. c. Sandy 

 post-oak woods, near Industry. August. We have it in cul- 

 tivation, from Lindheimer's seeds. The flowers are rose-color 

 or deep flesh-color, and about two inches in diameter ; the 

 rays large and conspicuous, but often irregular, and some of 

 them palmate. 



267. Actinella linearifojlia, Torr. fy Gr. I. c. De- 

 vol. v. 17
