principal characters of the variety of B. ciliàris, named 
8, melanosticta in Ach. Meth., and our plant may prove 
to be this variety. I have little doubt it belongs to B. 
ciliaris. The original B. leucómela of Ach. Meth. was 
a West Indian plant; and the lichen so named in 
Hooker's British Flora, is there said to be considered by 
. Borrer a mere variety of B. ciliaris. 
B. furfuracea, Ach. If this be what is intended by 
** Bórrera purpuracea, Spreng.", which is made a. sy-. 
nonym of Evérnia prunastri in the Massachusetts Cata- 
logue, it is certainly a mistake. 
The Borrera furfuracea of Acharius is a species uni- 
versally received, and distinguished from Evérnia prun- 
ástri, by evety botanist whose works I have examined, 
from the time of Linneus, who also made of them two 
species of lichen. There is therefore no doubt that the 
reference of the Catalogue, without any authority to 
support it, is erroneous. But I have not as yet been 
able, (even-with the help of authentic foreign specimens 
of both lichens), to distinguish them as Massachusetts 
plants. I have gathered frequently what I have taken 
for both plants, and both are labelled in my collection 
as found in this vicinity ; but there is to me a confusion 
in PENA to them yh I cannot dispel.
