CONCLUSION. 
71 
new and rare plants collected by himself, besides 
Kin, Boyken, Baldwin, Nuttal, Elliot, Ware, 
Leconte, Schweinitz, &c., from Florida and Ar- 
kanzas to Labrador, I may find there additional 
materials for this Flora ; therefore, the delay 
that may occur in the publication of the num- 
bers, will be compensated by the additional new 
plants I may be able to describe. 
I shall either continue to give monographs of 
some remarkable or rich genera, beginning with 
Kuhnia , Gentiana , JL echea, Hypericum , &,c., 
or I may give series of new Species from inte- 
resting localities. 
I may also pay particular attention to our 
New Genera, many of which are improperly 
referred as yet to akin Genera. 
As to the Natural Orders of our Plants, my 
general views and examples have been given in 
my preface, and will be found in the Introduc- 
tion to the Flora Telluriana. 
It is again recommended to our Botanists to 
study well the natural affinities and disparities 
of Genera and Species, both of which they have 
often heretofore either neglected or overlooked.
