NB.—There are two other phenogamic plants, 
of which I possess leaves only, and cannot cer- 
tainly indicate even their orders. One is pro- 
bably an Umbelliferous plant, from the neigh- 
bourhood of Horta, in Fayal: the other may be 
a large-leaved Composita, from the Caldeira of 
Fayal. -The total number of species, in both 
collections together. amounts to four hundred 
Flowering plants and thirty-four Ferns, etc. But 
among the Flowering plants enumerated, there 
" are at least twenty introduced species, and many 
others which probably are in the same condition. 
Some small further abatement may be made, for 
species counted twice over, under different names 
(see Tolpis umbellata, Hypericum decipiens, etc.), 
although I have endeavoured to reduce the num- 
ber of these as far as possible. And when we 
observe how many in the list are the common 
weeds of South Europe, which emigrate with 
agriculture, it may well be doubted whether the 
true Azoric Flora, as far as yet ascertained, 
reaches to three hundred species of Flowering 
plants. There is a strong presumption that 
several additional species would yet be discovered 
by botanists who extended their researches over 
other parts of the islands and saw them at a 
different season. About seventy of the species 
collected by Messrs.. Hochstetter and Guthnick 
are wanting in my own collection; and this 
latter, in turn, has about one hundred and ten 
species which apparently were not found by those 
two travellers.
