HISTORICAL SKETCH. 
Decandole, Sheperd, Haworth, Tratenick, Sen 
ber, Moricand, Bory, Swainson, Romer, 
Botanical travelers who merely come to ex- 
plore our Plants in order to send them to Eu- 
ropean Gardens or Herbals,are also numerous : 
the fruits of their exertions are chiefly made 
known to us by European Writers. Such were 
Kalm, Mason. Michaux, Vanderschot, Casti- 
gliorre, Bose, 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 plauts. 
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, Groom, 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, Clifford, 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.
