INTRODUCTION,

One of my main future works wili 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 Pr units, Plant ago, Gentiana , Eu- 
phorbia , Vaccinium , Andromeda & c 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 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 , 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.
