difference can be readily seen hy means of an ordinary lens. It 

 occurs here and there up to 1700 feet or higher on the northern 

 face of Slievemore and forms part of the hummocks, already alluded 

 to. It seems, however, to be more at home on rocky ledges, where 

 the finest tufts were found, unmixed with other hepatics. It was 

 first detected by Mr. J. B. Duncan. We had planned to investigate 

 its distribution along the range of hills, of which Slievemore forms 

 the northern limit, but the weather proved unfavourable.

Bazzaiiia frilohafa (L.) Gray; B. tricrenata (Wahl.) Pears.; 

 B. Pearsoni (Steph.) Pears., a beautiful and exceedingly rare plant, 

 Killarney hitherto being the only known station. It covers ledges of 

 rocks at 1700 feet, growing with Scapania nimhosa Tayl. and 

 S. ornifhopodioides (With.) Pears. Mr. Pearson and Canon Lett 

 first found it in this locality.

 Tayl., D. Moore in his Report on Irish llepaficw writes : — " Hab. 

 Among the larger mosses etc. On Brandon Mountain, Co. Kerry. 

 Dr. Taylor. I know nothing of this ])lant further than the quotations 

 transcribed testify." This record dates from 1818 and was the only 

 one for Ireland. It is apparently rare on Slievemore, only a few 

 stems being found, distributed here and there among S. ornitho- 

 23odi oides Sind Bazzania tricrenata and Bea?'soni on ledges of rocks at 

 an altitude of about 1700 feet. Mr. Macvicar found it at Moidart, 

 Argyllshire, in 1898, and since then it has been discovered on Ben 

 Nevis and Glen Nevis, Avhere I gathered it under the guidance of 

 Mr. H. H. Knight in August 1909. In October of the same year, 

 I met with it among the scree in one of the cwms of Glyder Fawr, 

 Carnarvonshire. It is one of the most beautiful as well as the rarest 

 of our hepatics.
