— Extremely rare. I 



found a single plant on Bulbein Mountain, August, 1879. 



Athi/rium Filix-fcemina, Both. — I gathered a remarkable M sport" 

 of this fern amongst cliffs behind Lough Sesiagh, near Dunfanaghy. 

 It bore spores upon the upper as well as the lower surface of

 Chelsea, to whom I sent specimens, considered it quite a new variety.
