Hypericum
Also known as Hofariqun, St. John's Worts
Hypericum is a genus of flowering plants in the family Hypericaceae (formerly considered a subfamily of Clusiaceae). The genus has a nearly worldwide distribution, missing only from tropical lowlands, deserts and polar regions. Many Hypericum species are regarded as invasive species and noxious weeds. All members of the genus may be referred to as '''St. John's wort, and some are known as goatweed'''. The white or pink flowered marsh St. John's worts of North America and eastern Asia are generally accepted as belonging to the separate genus Triadenum Raf.

Hypericum Les millepertuis forment le genre Hypericum, composé d'environ 400 espèces réparties dans le monde entier sauf dans les déserts et les régions arctiques (et sauf sous les tropiques en dehors des zones montagneuses). Les millepertuis sont rattachés à la famille des Hypéricacées selon la classification phylogénétique APG III (2009) ou à celle des Clusiacées selon la classification classique de Cronquist (1981).

En fait, ils correspondent à des glandes translucides donnant l'impression d'une multitude de minuscules perforations, qui renferment une huile essentielle. Le nom de genre Hypericum vient du grec hupo « presque », et ériké, « bruyère », en référence à certaines espèces qui évoquent des bruyères[2]. Descri

The white or pink flowered marsh St. John's worts of North America and eastern Asia are generally accepted as belonging to the separate genus Triadenum Raf.
Hypericum is unusual for a genus of its size because a worldwide taxonomic monograph was produced for it by Norman Robson (working at the Natural History Museum, London). Robson recognizes 36 sections within Hypericum.
