country of H. Elatum itself is involved in doubt ; for long it was 

 supposed to have come from North America, but it is quite 

 unknown there in a wild state. It is therefore not improbable 

 that Hypericum Elatum is a cultivated form of H. Anglicum. On 

 the other hand, it remains to be proved that H. Anglicum is not 

 itself an escape from cultivation, so that the attention of collectors 

 is earnestly called to this species.
