Hypericum (pronounced /ˌhaɪˈpɪərɨkəm/)[1] is a genus of about 400 species of flowering plants in the family Clusiaceae, subfamily Hypericoideae (formerly often considered a full family Hypericaceae).
'''''Hypericum''''' ({{pron-en|ˌhaɪˈpɪərɨkəm}})<ref>''Sunset Western Garden Book,'' 1995:606–607</ref> is a [[genus]] of about 400 [[species]] of [[flowering plant]]s in the [[family (biology)|family]] [[Clusiaceae]], [[subfamily]] [[Hypericoideae]] (formerly often considered a full family Hypericaceae).
The genus has a nearly worldwide distribution, missing only from tropical lowlands, deserts and polar regions. All members of the genus may be referred to as St. John's-wort, though they are also commonly just called hypericum, and some are known as tutsan. The marsh St. John's-worts are nowadays separated in Triadenum.

All members of the genus may be referred to as '''St. John's-wort''', though they are also commonly just called '''hypericum''', and some are known as '''tutsan'''. The marsh St. John's-worts are nowadays separated in ''[[Triadenum]]''.
St. John's-worts vary from annual or perennial herbaceous herbs 5–10 cm tall to shrubs and small trees up to 12 m tall. The leaves are opposite, simple oval, 1–8 cm long, either deciduous or evergreen. The flowers vary from pale to dark yellow, and from 0.5–6 cm in diameter, with five (rarely four) petals. The fruit is usually a dry capsule which splits to release the numerous small seeds; in some species it is fleshy and berry-like.
