HYPERICACEZA. 
HYPERICUM CALYCINUM. 
Loudon, v. 1. 400. 
It is very doubtful whether this can properly be Hypericum 
: : calycinum 
said to be a native of the west of Ireland and | 
Scotland. It certainly grows in several places in 
Miese Coulltiies, but there is great reason to 
suppose it is only naturalized, as it is a very 
hardy plant, spreading rapidly and extensively, 
and easily establishing itself in favorable situations. 
Indeed I think the remarkable thing is that it 
should not have become more common as a 
naturalized plant. It appears to be in reality a 
native of Turkey (See Sir James Smith in Linnean 
Transactions v. to. and in English Botany, v. 20,
