SINGENESIA. SUPERFLUA, 151 



flowered, flowers large as the preceding, and of the same 

 colour; calix remarkable for its smoothness. Pappus dou- 

 ble; seed elliptic-obovate, villous. 



4. mai'iuiui. Corymb simple: stem and leaves for the 

 most part sericeoush sublanugmous; leaves sessile, nearly 

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

 denticulate; fastig-iate peduncles and calix viscidly pu- 

 bescent. ^. falcata. L falcata? Vn. Corymb coarctate, 

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

 riceously sublanuginous; leaves sessile, nearly equal, ob- 

 long-lanceolate, canaiicqlate, acute and spreading; nriargin 

 remotely denticulate; fastigi-ue peduncles and calix vis- 

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

 ly a'distinct species from the preceduig-; tlie flowers are 

 more numerous, and the leaves opaque and remarkably- 

 channelled; flowers b;ight yellow and abundant, corymb 

 sometimes effuse, but usually crowded; rays oblong^, ti'i- 

 dentate. Pappus double, seed obovate and villous. 



5. ^ramnifoUa. Cor}mb compound; stem and leaves 

 covered with an appressed sericeous pubescence; leaves 

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

 glandularly pubescent. Erigeroji nerva-um, Wiild. Hae. 

 From Delaware to Florida. 



6. arg-entea. Every where sericeous; corymb compound; 

 leaves entire, lanceolate-linear, erect and very acute; ca- 

 lix turbinate, pubescent, but not glar.dular. H^b. From 

 Virginia to Florida. Very nearly allied to the preceding 

 which it generally resembles, it is, however, narrowei* 

 leaved, and ought therefore to have been considered the 

 ^raminifolia of Michaux, but the calix is not glandular; 

 the leaves of Persoon's argentea are then those of Mi- 

 chaux's plant. I'he 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 10 in number; the pa[)pus dis- 

 tinctly double, and the seeds obov;ite and villous. 



7. villosa. Subdccumbent and hirsutely villous; leaves 

 entire and sessile, linear-oblong, subspathulale, acute, 

 lower part ciliate, margin scabrous; stem branched, 

 branches subcorymbose, flowers fastigiate. Hab. On the 

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

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

 many from the same root, producing a double pubescence, 

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

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

 villous. 



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

 subcorymbose; lower leaves petiolate, subdentate, th'; up
