nera, that I was compelled to take up the sub- 
ject of Generic reform simultaneously with this 
new flora. This has greatly increased my la- 
bors and delayed the publication ; but vastly 
enlarged my field of botanical researches, now 
based on generic accuracy. 
In fact till lately most of the Botanists, both 
here and elsewhere, were perfectly satisfied 
with the Linnean Genera, and thought they had 
done their utmost when they referred the Lin- 
nean or new species, quite at random to those 
Linnean Genera ; often avoiding or neglecting 
to notice their peculiar floral characters, not 
seldom at variance with the Genera referred 
to. The labors of Adanson, Jussieu, Necker, 
Mcench, Lamark, Sc c. upon generic reforms 
were often overlooked or neglected. At last a 
better feeling has been prevailing, and the mo- 
dern improvers Decandole, Agardh, Robert 
Brown, Lindley, See. have restored many of the 
old Genera, or further corrected generic no 
menclature. 
As I rank among these botanical reformers 
ever since 1808 when I first published new Ge- 
nera, and 1815 when I published the outlines of 
my reformed Natural Families, it was just 
and proper that I should resume these investi- 
gations, now that I mean to give the results of 
a whole life of botanical travels, discoveries and 
arduous researches. This shall then be done 
in a colateral work published at the same time, 
but kept apart, which I shall call Flora tellu- 
riana or synoptical mantissa of 2000 new fa- 
milies, Genera and species of plants of the whole 
earth. There most of my generic and other 
reforms will be elucidated, and 1 shall merely 
refer to them in this N. Araer. Flora.
