^o^yered, flowers large as the preceding, and of the sair.e 

 colour; calix remarkable for its smoothness. Pappus dou- 

 ble; seed elliptic -obovate, villous. 



4. marlana. Corymb simple: stem and leaves for tha 

 most part sericeotisU sublanuginous; leaves sessile, nearly 

 equal in size, oblong-elliptic, subovate, obtuse, distantly 

 denticulate; fastigiate peduncles and ealix viscidly pu- 

 bescent. fi. falcata. I. fakaia? Ph. Corymb coarctaie, 

 many-flowered, simple or compound; stem and leaves se- 

 rlccously sublanuginous; leaves sessile, nearly equal, ob- 

 loni^-lanceolate, canaliculate, acute and spreadmg; margni 

 remotelv denticulate; fastiginte peduncles and calix vis- 

 cidly pubescent. Hab. In New Jersey, common; scarce-- 

 ly a distinct species from the preceding; the flowers are 

 more numerous, and the leaves opaque and remarkably 

 channelled; flowers bright yellow and abundant, corymb 

 sometimes eftuse, but usually crowded; rays oblong, in- 

 dentate. Pappus double, seed obovate and villous. 



5. graminifolia. Corymb compound; stem and leaves 

 covered with an appressed sericeous pubescence; leaves 

 entire, linear-lanceolate, erect and acute; calix oblong,

 From Delaware to Florida. 



6. aigentea. Every where sericeous; corymb compoundj 

 leaves entire, lance'olate-linear, erect and very acute; ca- 

 lix turbinate, Jjubescent, but not glandular. Has. From 

 Virginia to Florida. Very nearly allied to the precedin-g 

 which it generally resembles, it is, however, narrower 

 leaved, and ought therefore to have be«n considered the 

 grambufolia of Michaux, but the cahx is not glandula?; 

 the leaves of Persoon's argeniea are the« those of Mi» 

 chaux*s plant. The pubescence in these 2 species is ex-^ 

 tremely singular, appearing like white silk laid evenly and 

 longitudinally along either surface of the leaf; the radial 

 florets are also only 8 or IQ in number; the pappus dis- 

 tinctly double, and the seeds obovate and villous. 



7. villosa. Subdecumbent and hirsutely villous; leave* 

 entire and sessile, linear-oblong, subspathulate, acute^ 

 lower part cUiate, margin scabrous; stem branched, 

 branches subcorymbose, flowers fastigiate. Has. On the 

 plains of the Missouri; from its confluence to its source? 

 Amellus villostis. Ph. 2. p. 564. Obs. Perennial: stems 

 many from the same root, producing a double pub^scenccv 

 both villous and pilose; rays golden -yellow, about 25, en- 

 tire, and linear-oblong. Pappus double; seed obovate,. 

 villous. 



8. scabra. Blenuial; stem hispid and branched; branches 

 »ubcorymbose; lower leaves petiolate, subdeirtate, the up-
