They are herbs or shrubs with cymose yellow flowers. H. 
perforation, or St.-John's-wort, is a mnall species, which 
derives its specific 
name from the fact 
that the pellucid 
dots common to the 
leaves of most of the 
species are in it 
peculiarly conspicu- 
ous, so as to give 
the leaf the appear- 
ance of being per-

ed by Eosenbusch, is by Tornebohm, who designates under 
the name of hyperite a rock intermediate in character be- 
tween normal gabbro and olivin gabbro. Also called hy-

Hypericum is the type. It contains 8 genera and 210 
species. They are herbs, shrubs, or (rarely) trees, with 
simple, opposite (rarely whorled) leaves, which are often 
dotted with resinous glands. They have terminal or axil- 
lary, solitary, cymose or paniculate flowers, usually yellow 
or white, with 5 sepals and usually 5 petals, and the numer- 
ous stamens usually united into 3 or B bundles at their base.
