Craigha Moira, Cunnamara. MrWm. MucCalla. Fl. Aug. Sept. T^ . 

 — The broad, almost exactly ovate leaves, with a great proportion of 

 almost white surface beneath, would seem at first sight to distinguish this 

 specifically from the preceding, and it is a remarkable fact that it was dis- 

 covered on the Sierra del Peral in Asturiain the sameyear as in Ireland. 

 No other station is at present known for it. Can Sir J. E. Smith have 

 had this in view when he describes the leaves of E. Tetralix as " ovate," 

 or lanceolate ? Near Truro, Mr Watson finds what is probably a hybrid 

 between ihe latter and E. ciharis, much resembling our E. Mackaii. 



3. E. cinerea, L. (Jine-leaved Heath) ; anthers with 2 serrated 

 appendages at the base, style a little exserted, corolla ovate, 

 stigma capitate, leaves ternate. E. Bot. t. 1015.
