CLASS XVIIT. ORDER 1. | HYPERICUM. 1011 
Shrub; flowering in July. 
The name of Tutsan seems to be derived from the French Toute- 
saine, or all-heal, from the bruised capsules being formed into a kind 
of poultice, and applied to recent wounds. It is not now so highly 
esteemed for its healing powers, and is only valued as an ornamental 
flowering shrub ; it flourishes well on the borders of shrubberies or 
plantations, in a sandy or light soil; its leaves have a pleasant odour 
when rubbed between the fingers, and its large cymes of flowers are 
very handsome.

This is an extremely pretty plant, growing freely upon banks and 
borders of bushy places or plantations, where it is partly shaded; its 
flowers are large, and very handsome, and it continues flowering a 
long time. It is a common cultivated plant, having, it is probable 
in the above stations, escaped from gardens, and thus naturalized 
itself.
