Hypericaceæ

Hypericaceæ, or HYPERICINÆ, a natural order of about 300 known species, trees, shrubs, and herbaceous plants, widely distributed over the world, and in very different climates, but particularly numerous in North America. The species of Vismia yield a substance resembling gamboge. Many of the Hypericaceæ belong to the genus Hypericum, or St John's Wort (q.v.).
