INTRODirCTIOX. 23 



Gronovius did for Clayton, and Wildenow for 

 Loureiro ! 



My florula Mandanensis and Missurica based 

 upon the plants and specimens of Bradbury, 

 Lewis, Miller and Beck, written between 1817 

 and 18*20, but never published, and a copy sent 

 to England was lost. Other similar mpts. of 

 mine, yet unpublished, I deem useless to enu- 

 merate. 



Between 1816 and 1818 I rectified many er- 

 rors of Pursh, Nuttal, Barton, Bigelow, Elliot 

 &c. in reviews, and published 40 new plants 

 In 1819 my 50 N. G. of American plants were 

 published in Journal de physique of Paris. 



In 1820 my annals of nature had 25 N. G. 

 and 124 N. Sp, of animals and plants, and my 

 monographs of Rubiacea, Rosa, Houstonia, 

 Lysimachia, Convolvulus &c. were published in 

 the A finales des Sciences physiques of Bruxels. 



In 1825 I proposed 66 American N. G. in 

 my Neogenyton. In my Medical flora of the 

 United States 1828 to 1830 I gave many N. Sp. 

 and figures, with monographs of Vitis, Genti- 

 ana, Heuchera, Trillium, Unisema, <^c. 



In 1830 and 1831 I sent to Decandole at his 

 request several mpts on 16 New families, and 

 175 New Genera of Plants chiefly North Amer- 

 ican, among which 60 N. G. of Composite be- 

 sides 90 New Species of the same Order, and 

 45 N. Sp. of other orders, with 188 Specimens 

 of rare, new or doubtful plants. 



In my Atlantic Journal 1832 to 1833, I gave 

 150 N. G. or Sp. of Plants. In 1833 was be- 

 gun my Herhar. Raf. with many new plants, 

 Genera, and Catalogues of my discoveries, bo- 

 tanical collections «fcc.
