Hypericaceae A.L. de Jussieu. St. John's-wort Family.

Key to Hypericaceae

A family of 7-9 genera and 480-560 species, herbs, shrubs, and trees, nearly cosmopolitan. It appears from molecular analysis that recognition of the Hypericaceae is (after all) warranted. Hypericum is in a clade with Podostemum and Bonnetia, sister to a clade including Clusiaceae s.s. (Savolainen et al. 2000), and unless the morphologically very different Podostemaceae is to be included in a broad Clusiaceae, Hypericaceae and Podostemaceae must be recognized.
