10 HISTORICAL SKETCH. 



Decandole, Sheperd, Haworth, Tratenick, Sei- 

 ber, Moricand, Bory, Swainson, Romer, &:c. 

 Botanical travelers who merely come to ex- 

 plore our Plants in order to send them to Eu- 

 ropean Gardens orHerbals,are also numerous : 

 the fruits of their exertions are chiefly made 

 known to us by European Writers. Such were 

 Kalm, Mason. Michaux, Vanderschot, Casti- 

 glione, Eosc, Palissot, Turpin, Acosta, Rich- 

 ardson, Goldie, Drummond, Douglass, Macnab, 

 Enslen, Lyons, Kin, Bradbury, Rustan, Berich. 

 Among our native traveling collectors, I must 

 mention Bartram, Lewis and Clark, James, 

 Schoolcraft, Baldwin, Peters, Cozen, Ware, 

 Wyeth, Gates, Houghton, Pitcher, Walton, &c. 

 who have often explored far regions, and dis- 

 covered many new plants. 



The distant regions of Origon have chiefly 

 been visited by Makenzie. Langsdorf, Scooler, 

 Douglass, Wyeth, Nuttal, Walton ^c. While 

 the Regions of Florida, have been explored by 

 Bartram, Roberts, Williams, Cozen, Kin, Bald- 

 win, Ware, Croom, Gates, Leitner, &c. But 

 both as well as Texas will afford novelties for 

 many years to come, and I have myself many 

 of them to describe in this Work, received from 

 various quarters. 



Amateurs as Horticulturalists, or friends of 

 Science, or Patrons of explorers, rank also 

 among the promoters of Botany ; I may men- 

 tion among those known to me or who have 

 helped my researches, Clinton, Forrest, Mease, 

 Adlum, Marshall, Chfford, Shultz, Carr, 

 Walsh, Betton, Haines, Sitgraves, Mrs. Wal- 

 lace, Mrs. Betton ^-e : many more exist all 

 over the United States ; Stephen Van Rensa- 

 laer has been a great patron of Eaton : Ma- 

 clure and Collins of various Botanists.
