IWTRODXTCTIOir. 7 



One of my main future works will be a com- 

 plete Sylva of North America on our Trees and 

 Shrubs reduced to natural orders. Another on 

 our Ferns &c. There will be much to do yet 

 in all the botanical classes, before they be pro- 

 perly rectified and made permanent. There is 

 an ample field of observations and researches in 

 the vast regions extending- from Florida to 

 Texas, Origon and Boreal America, and con- 

 taining more Gen. and Sp. than Europe; even 

 excluding the Mexican and Tropical States till 

 Panama, that afford a vegetation equaly fruitful. 

 Some of my future Monographs of the Genera 

 or groups Prunus^ Planta'go^ Gentiana^ Eu- 

 phorbia, Vacciniunfj Andromeda Slc will con- 

 tain from 40 to 80 Species. 



In this last part of my Supplemental Flora, I 

 will chiefly describe some of the most select and 

 rare plants or shrubs which I have in my Her- 

 barium ; they are all figured in my Autikon 

 like the others. — And I can vouch that they 

 are all as good and genuine Species as any of 

 our modern botanists, and much better than 

 one ha f of the linnean Species of old, often 

 blending half a dozen; as in the Genera Gera- 

 nium, Lichen, Conferva, Agaricus, Aster, Eu- 

 phorbia, Veronica, Justicia, and 100 similar 

 families rather than Genera, that included 10 

 to 50 Good natural Genera, comingled as men 

 are comingled with the Monkeys, and Bats with 

 Birds ! ! ! by many ignorant men or pseudo- 

 philosophers lacking the sagacity of perceiv- 

 ing distinctions of parts and forms.
