The authors of ' Synopsis Hepaticarura ' 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. harhata, 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. Lyonif.

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. 

 la ' Hepaticje Pyrenaicie ' 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 po-sibly 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 toothed. 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 J^. culearis. 



t Dr. Grateloup mentions in his list "Jg. setiformis, Ehrh. Hab. in 

 sylvis ad terram et ad arb. truncos. Dax. Lesperon. Sauhagnac ;" 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.
