that it will be found in 12 of those counties, if that of 

 Huntingdon, the 13th, should be a real exception. In 

 ages past, before drainage and cultivation had banished 

 the heath and bog plants from so much of England, this 

 would doubtless be one of the commonest native plants of 

 Britain ; however little such may now apj)ear to be the 

 case in the eyes of the metroiDolitan botanist. Under 

 this sj)ecies I reckon the localities of "E. polj'^stachyon " 

 and " E. angustifolium " of British botanists ; though 

 possibly some few of the stations recorded for the former, 

 may belong to E. latifolium.

Native. Uliginal, Ericetal. Sparingly scattered through 

 Britaui, and quite rare in the first six or seven provinces, 

 according to existent records. But the localities at pre- 

 sent on record are probably much below the actual census 

 of the species, which has doubtless been frequently con- 

 fused with E. angustifolium. In stating the provincial 

 area above I have been obliged to assume this species 

 intended in one case, where another name has been used ; 

 that is, in Flora Devoniensis, where the E. polystachion, 

 of Dartmoor, is described with "flat'' leaves, and would
