This fine species was discovered June, 1864, at Ronas 
Hill, Shetland, by A. Me. Kinlay, Esq. In general habit 
J. saxicola resembles J. minuta, but the leaves are more 
closely imbricated, the anterior lobe smaller, and the poste- 
rior curved forwards, so that the back of the frond looks 
terete. The leaves are of firm texture, olive-brown, scarcely 
altered when dry, areolation dotted. 
J. saxicola is not unfrequent in Norway and Sweden, and 
is also found in alpine districts through Europe ; so that I 
have long looked for it from Scotland. Some years ago the 
late Dr. Greville was kind enough to lend me his duplicates 
of Hepaticse, and in a paper with J. orcadensis from the 
Southerland mountains, I found two stems of J. saxicola, as 
if they had been picked out of some tuft ; but as there were 
European specimens in the same packet, I thought they 
might have got there accidentally. 
The synonymy of J. saxicola was long in a confused state. 
Linnseus, in the Flora Suecica, confounded it with J. resupi- 
nata Dillenius, which was probably Scap. oequiloba.
