Obs. — Dr. Hooker wrote in his " Brit. Jung," : '"' There are few 

 naturalists to whom Cryptogamic botany is more indebted than 

 to Mr, Dickson. In the genus Jungermania his numerous 

 additions to the list of British species are well known. The 

 present is one of many collected since the publication of the 

 fourth fasciculus of his Flantce OryptogamiccB in the Highland 

 mountains of Scotland, which he kindly communicated to me ; 

 and I have great pleasure in distinguishing it by his name."
