Flora Prittsburghensis

Hypericaceae

St. John’s-Wort Family

In some systems this family was included in the Guttiferae or Clusiaceae. So it was in the “Check List of the Vascular Flora of Allegheny County,” but current botanical wisdom agrees with Gray in maintaining the Hypericaceae as a separate family.

St.-John’s-Wort (Hypericum perforatum). The thick wad of stamens in the middle of the flower is characteristic of St.-John’s-Worts, most of which also have bright yellow flowers. The lush growth of tidy opposite elliptical leaves makes this a handsome plant, and it carries its flowers proudly.

Hypericum punctatum

Hypericum spathulatum

Hypericum mutilum

Hypericum virginicum
