As all the Ericacece are regarded as typical calcifuge plants, it 

 may be of interest to put on record the habitats from the calcareous 

 areas, in which it not infrequently occurs, in soils often shallow, 

 relatively poor in humus, and with the roots practically in contact 

 with the limestone. Ogmore Down ! Miss B. Southerndown. V. 

 Porthcawl ! H. Horton to Oxwich ! Ed. It appears to tolerate 

 to a certain extent the mountain limestone, but not the Lias.
