The authors of ‘Synopsis Hepaticarum’ had surely never seen 
correct examples of this when they referred it to Jg. socia, N. ab E., 
and their description of it, ‘‘foliis laciniis obtusis,” is quite at variance 
with specimens I possess from Messrs. Lyon and Taylor. It is sin- 
gular that its near ally, Jg. barbata, Schreb., one of the commonest 
species in our mountains, should never have been observed in the 
Pyrenees. Dr. Grateloup indeed mentions it in his list as growing 
at the extreme western angle, ‘‘ in montibus petrosis Cambo prope 
Bayonam,” but without seeing his plant I dare not say that it is 
different from Jg. Lyonit.

I am doubtful whether Dickson meant this species by his Jg. ven- 
tricosa, Fasc. 2. p.14. He gives no figure, but cites figures of Mi- 
cheli and Dillenius, which are certainly little like our plant, and adds, 
** Folia in nostra profundius fissa, quam in figuris Michelii et Dillenii 
depinguntur,” which is still more at variance with the species as 
figured by Hooker. Dr. Gottsche informs me that when this plant 
grows on rotten wood, where it often assumes a purplish tinge (as in 
some of my Pyrenean specimens), it is the Jg. porphyroleuca of Nees. 
In ‘ Hepaticee Pyrenaice’ I had considered this form as possibly Jg. 
* The plant alluded to at the close of my description of Jg. Bantriensis 
(‘ Annals,’ 1844) as gathered by Mr. Ralfs at Dolgelley, is possibly distinct 
from both the above. The three perianths in my possession are all subtri- 
angular on the section, the dorsal face being the narrowest, and in one peri- 
anth the two lateral angles are winged and toothea. If it must be referred 
to one of the two, it will be to Jg. acuta, as it has the gibbous sinus of the 
leaves characteristic of that species. Mr, Wilson, to whom I am indebted 
for the specimens, has called it Jg. culearis. 
+ Dr. Grateloup mentions in his list “Jg. setiformis, Ehrh. Hab. in 
sylvis ad terram et ad arb, truncos. Dax. Lésperon. Saubagnac ;” but as 
I searched for it in these stations without success, I cannot include it in my 
enumeration. It would be indeed remarkable to find in the plains of the 
south of Europe a species which grows most profusely in Lapland (Wahlen- 
berg), and which when it extends farther south is uniformly alpine.
