(apart from H. bifolia) is reported from provinces 12 3 4 

 5 6 * 8 * 10 11 ^ 13 14'f*16. And, on the other side, H. 

 bifoUa (apart from H. chloranj;ha) is recorded for provinces 

 234**78***** 14 * 16. Probably each is scat- 

 tered generally through Britain, with the exception of the 

 North Isles, from which neither of them appears to have 

 been hitherto reported.

Native. Pascual, Ericetal. So scarce a plant in Eng- 

 land, especially in the southern provinces, as almost to 

 warrant the assignment of it to the Scottish type, rather 

 than the British ; notwithstanding the generality of its 

 area, when tested by provinces. I have seen it, or it has 

 been reported by other botanists, altogether in about 5Q 

 counties. Among the remaining 26 counties, several ap- 

 pear so very likely to produce it (Orkney, Caithness, Stir- 

 ling, &c. &c.) that I cannot place the estimate so low as 

 60 ; and possibly 75 might have come nearer the reality 

 than 70.
