[Eead January 14, 1900.] 



Heeetttth I lay before tlie Royal Irish Academy the result of many 

 years collecting and research among the Hepaticse which are to be 

 found in the wild mountainous barony of Corkaguiny, which I have 

 visited in search of these curious plants many times during the past 

 20 years. 



I have been assisted to make these escui'sions by grants from the 

 Elora and Eauna Committee of the Royal Irish Academy, and I have 

 also availed myself of the opportunities afforded me, when collecting 

 plants there for the Science and Art Department, Dublin. 



Among the eminent bryologists who previously collected Hepatiese 

 in the Dingle Peninsula I may mention Dr. Thomas Taylor, of Kenmare, 

 who gathered many rarities there about the year 1813, among them 

 Scapania ornithopodioides was found near the summit of Mount Brandon, 

 which rises to 3120 feet. The celebrated bryologist "William "Wilson, 

 Esq., of "Warrington, visited the peninsula with Dr. Taylor, in 1829, 

 and among the rarities recorded by him is the rare Scapania 

 ornithopodioides fi'om where Taylor previously found it, and in the 

 Maghanabo glen he found the rare Dumortiera irrigua, and he was the 

 first to publish the plant as a native of the British Isles, in the English 

 Elora, in 1833. In more recent years Mr. Mitten, of bryological fame, 

 followed in the footsteps of Messrs, Taylor and "Wilson, and collected 

 many rarities, and it is owing to the kind and accurate directions from 

 him that Canon Lett and myself were able to re-discover Scapania 

 ornithopodioides on the rocky north-east side of Mount Brandon. It is 

 also interesting to note that the rare Dumortiera collected by "Wilson in 

 1829, still flourishes in the Maghanabo glen.
