Plants of this species are generally larger, and of a lighter brown 

 colour than those of E. tamarisci. The involucral bracts are en- 

 tire. The leaves are destitute of the line of moniliform cells, 

 which are so obvious in E. tamarisci, and the cells in them are 

 larger, with the walls thicker. 



Hab. On rocks and on trees. Erequent in the County of Kerry ; 

 Co. Donegal ; Lough Bray, "Wicklow.
