 Obs. The only species of this genus which attains the alpine re- 

 gion is L. serpyllifolia, but it is always unfertile there. L. ovata 

 finds in the Pyrenees its only continental station, and but the second 

 known, the first being the south-west corner of Ireland, around 

 Ban try and Killarney. L. calcarea is confined to the rock indicated 

 by its name*. 



* I did not observe Lejeunia minutissima in the Pyrenees, but it will not 

 be out of place to mention here that I had lately the opportunity of exami- 

 ning Sir J. E. Smith's original specimens of this species, gathered in the New 

 Forest by C. Lyell, Esq. in 1806, and figured on plate 1633 ofEng. Bot., 

 and that they agree as to the presence of stipules and every other essential 

 character with Hooker's figure in ' Brit. Jungermanniae,' t. 52. Dr. Taylor 

 was therefore in error (as I have always suspected) in maintaining Sir J. E. 

 Smith's plant to be the exsiipulaceaus species ; but as my distinguished and 

 lamented friend was the first clearly to distinguish the latter, I propose that 

 it shall bear his name, and the amended synonymy will stand thus : 



Lejeunia minutissima, Smith! in Eng. Bot. t. 1633 (sub Jung.) ; Hook. 

 Br. Jung. t. 52. Jungermannia ulicina, Tayl. ! in Trans, of Edinb. Bot. 

 Soc. 1841, i. p. 115. Lejeunia ulicina, Syn. Hep. p. 387.
