The Connemara station for Erica Mackaiana is peculiar; 
according to my observation it occurs only on a small 
rocky eminence which rises out of a vast bog which is the 
home of E. Tetrcclix; as it grows in free flowering bushes a 
foot or more in height, it may readily be picked out from 
plants of E. Tctralix. 
A series of British and Continental specimens of the 
heaths named in this communication now lie on the tables 
for comparison with the living plant.
