INTRODUCTION. 7 



One of my main future works will be a conf- 

 plete Sylva of North America on our Trees and 

 Shrubs reduced to natural orders. Another en 

 our Ferns &c. There will bo 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, Plantngo, Gentiana<t Eu' 

 phorbia, Vaccinmm^ Andromeda SlcvjiW 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 half of the linnean Species of old, often 

 blending half a dozen ; as in the Genera Gera- 

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

 phorbia, Veronica, Jnsticia, 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.
