seem all to belong to one species, and to be so little different, and so 
gradually dissimilar, as to be scarce worthy of separate names, even 
in the light of varieties only " (Phytol. iii. 805). Аз will shortly 
be seen, I now think that he was nearly, if not quite correct in those 
remarks. Opinions formed after the examination of only a few very 
imperfect specimens, and therefore little more than guesses, are 
never either conclusive or satisfactory. Mr. Watson's own view, 
which was founded upon scores of specimens examined when alive, 
is, of course, nearly conclusive against that formerly held by me. 
Of the three Azorean plants then noticed (Bot. Gaz. 7. c. 63 & 64), 
two certainly do seem to belong to one species: the third (sent by 
Mr. Т. C. Hunt from St. Michael's) looks far more like a form of 
the true F. capreolata ; it is too incomplete for satisfactory deter- 
mination. The two first-mentioned specimens I now refer to the 
F. muralis (Sond.) with some confidence; and if Mr. Hunt’s broader- 
leaved plant is correctly joined to them, as was believed by Mr. 
Watson, we shall have arrived at the same result for the Azores 
that Mr. Lowe (Fl. Mad. 13) has done for Madeira, namely, that 
all the so-called F. capreolata of those islands is really the F. mu- 
ralis of Sonder. 
After reading Mr. Lowe's most valuable remarks (7. с.), I was 
led to re-examine my British specimens, in the hope of finding 
amongst them the F. muralis,—suspecting that my former F. 
agraria, which, in deference to the views of Dr. Walker-Arnott 
and Mr. Watson, Т had ceased to regard as a species, might be 
rightly so named. Although the result is a little different from 
that expectation, all my supposed F. agraria proving to belong to 
the F. confusa (Jord.), nevertheless I find amongst plants received 
from Mr. Leighton examples of the F. muralis. This is the more 
interesting from Mr. Jordan's remark, made in the year 1848, 
concerning F. muralis. He said, * specimina hujus in Gallia lecta 
nondum vidi;" and as it is not noticed in the third edition of 
Boreau's valuable * Flora of Central France,' nor in Lloyd's Flora 
of the West of that country, we may perhaps safely conclude that 
it has not even now been detected there. I possess an authentic 
specimen of F. muralis from Mr. Sonder himself, and another 
from the Island of Madeira, by whieh to determine the plant of 
Lowe. They accord very satisfactorily with each other and with 
the descriptions of the species as given by Sonder, Koch, A. Jordan, 
and Lowe. 
These plants, together with F. capreolata (F. speciosa, Jord.), 
F. pallidiflora (Jord.), and F. Borei (Jord.), combined with a few
