As I have already explained, the data on which these 
statistics are founded are imperfect, and hence the statis- 
tics themselves must be equally so. I therefore base on 
them no comparisons with the statistics of the Floras of 
Greenland, Norway, Scandinavia generally, or Britain ; nor 
do I wish at present to found on them any general con- 
clusions. JI abstain from such a subject farther than to 
point out the remarkable equality in numbers between 
the Phanerogams and Cryptogams, and to indicate the pro- 
bable extent to which the numbers in the prefixed table 
fall short of the number of plants at present actually 
natives of Iceland. I believe that future botanical research 
will increase the Phanerogams less extensively than the 
Cryptogams; and I believe farther, that whereas the fore- 
going tabular view sets down the total Icelandic Phanero- 
gams at 426, 450 is more likely to be the real number; and 
whereas the Cryptogams appear as 437, 550 is a more pro- 
bable minimum; so that I incline to estimate the Icelandic 
Flora as likely to be numerically represented more truly by 
1000. 
After the remarks which have preceded, it is perhaps un- 
necessary to repeat that my revised list of Icelandic plants 
is confessedly imperfect; but I wish this to be distinctly 
understood. It is imperfect in so far as it does not re- 
present the entire existing Flora of Iceland. I believe that 
many Phanerogams, and still more Cryptogams, remain 
to be added to the list by the labours of future botanical 
travellers. I can speak, however, with greater confidence in
