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 

 Knhnia, Gentiana, Lechea, Hypericum^ Slc, 

 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.
