TAPJ.'/OXIA. 479 



also collected it in the same glen, 1872 and 1874 ; also very 

 sparingly near a small waterfall at Lnggielaw, Co. Wicklovv. This 

 remarkable plant is very local in Ireland, and only occurs in the 

 warmest and most sheltered spots." — Dr. />. Moore, Pro. Bo//. 

 Ir'ixli Acad. p. G03 (1876). Kilhirney, Br. Carriu/jlon, and 

 others. 



Found on the Continent (Pyrenees, l>r. Spruce, Prof. Sc/iiii//jcr, 

 Italy), and in the Southern States of North America. 



Obs. — Our finest frondose species, and which seems to be 

 almost peculiar to the South of Ireland, as only two other 

 stations, where it has been sparingly collected, are known. 



When seen not likely to be confounded with any other of our 

 frondose species. 



Dr. Spruce and Prof. Sehitfncr consider it a variety of the 

 tropical Buuwrtlera hirs/ffa (Swartz), and Dr. Stephani in his Sp. 

 Jlcp. merges it with that species.
