18 R udb eckia fulgida. 



Root perennial. Stem about two feet high, terete, sometimes sim- 

 ple, often branched, hairy. Branches virgate, elongated, pedunculi- 

 form, one-flowered. Leaves oblong-lanceolate, remotely denticulate, 

 hispid on both sides and on the margin, the hair running regularly 

 from the base towards the apex; attenuated towards the base, and 

 sub-cordate, closely sessile, acute. The leaves on the pedunculate 

 stem small, not serrated nor cordate, but attenuated at either end, 

 and sessile. Lower and radicle leaves oval-lanceolate or oval, acute, 

 attenuated at base, and more distinctly cordate, with more and larger, 

 teeth, and distinctly three-nerved. Flowers solitary, terminal. Rays 

 oval, or oval-lanceolate, one-toothed or notched, about thirteen in 

 number ; gamboge yellow, paler underneath. Disk hemispherical, 

 auricula purple. Calix leafy, leaves lanceolate, hairy, acute, nearly 

 as long as the rays. Found in mountain and other meadows, and 

 on the borders of damp woods, from the northern to the southern 

 states, flowering from July until October. 



The genus of which a species is here figured, was dedicated by 

 Linnams to the memory of his countrymen, Oriof Rudbeck, father 

 and son, both alike conspicuous for their learning and botanical 

 attainments, and his predecessors in the botanical professorship at 

 Upsal. Linnaeus chose a genus allied to Helianthus, because a sun- 

 flower constituted a part of the coat-of-arms of the family of Rud- 

 beck.
