The genus '''''Hypericum''''' contains approximately 500 species which are divided into 36 sections as described by botanist Norman Robson.<ref name="TPL" /> This division into distinct sections is largely due to the fact that a genus-wide monograph was performed by Robson in 1977, which allowed for a comprehensive analysis of the genus's taxonomy.<ref name="Robson 1977" /> A phylogenetic study was more recently completed for the genus, which gave evidence to suggest that the genus ''Triadenum'' is a clade within ''Hypericum'' and that the genus ''Thornea'' is sister to ''Hypericum''. In addition, the study found that about 60% of the sections of ''Hypericum'' are monophyletic.<ref name="Nurk 2013" />

Almost all species of ''Hypericum'' are either perennial herbs, shrubs, or small trees, but the genus also contains a small amount of subshrubs and annual herbs.<ref name="Robson 1977" /> Most of its species contain hypericin or hyperforin and some are used for their healing properties in folk medicine. The species' leaves are always placed opposite, and are normally decussate.<ref name="Aqua Plants" /> Their flowers are generally homostylous, but very few are dimorphically heterostylous. The petals are normally golden yellow or orange, but some are white or cream, and are veined dorsally. They have 4–5 stamen fascicles, 2–5 ovaries, and 2–5 styles. Some species grow capsular fruit which are colored red or blackish.<ref name="Hypericum MySpecies" />

''Hypericum'' species can be found all over the world in temperate to tropical areas. The genus is most diverse in Turkey (~80 species) and China (~60 species), but can be found across Asia and Europe, in parts of Africa and South America, Australia, and across the United States and southern Canada.<ref name=":77"/> Non-native species have also been introduced into various regions of the United States and Argentina.<ref name="POWO"/> The genus are generally found in dry, desert areas to being in shallow water, and can be found from warm temperate climates to cold temperate climates.<ref name="Hypericum MySpecies"/>

Some ''Hypericum'' species are used as ornamental plants because of their large, spreading flowers.<ref name="A-Z RHS"/> These include ''H. aegypticum'', ''H. androsaemum'', ''H. calycinum'', and ''H. olympicum''. In addition, there are a number of hybrids and cultivars that have been developed for use in horticulture. Some notable cultivars are ''H. × moserianum'', ''H.'' 'Hidcote', and ''H.'' 'Rowallane'. Several species are also used for their medicinal properties, especially their ability to alleviate mild clinical depression, by drawing out the oily extract from the flowers.<ref name="Szegedi 2005"/> ''H. perforatum'' is the most potent out of all the species, and is the only species cultivated commercially for herbalism and medicine.<ref name="Klemow 2011"/> __NOTOC__

==Sect. ''Adenosepalum''== ''Adenosepalum'' Spach is divided into four subsections: ''Adenosepalum'', ''Aethiopica'', ''Caprifolia'', and the Huber-Morathii Group. These subsections contain eight, seven, eleven, and five species, respectively, giving the section ''Adenosepalum'' a total of thirty-one species. In addition, ''Adenosepalum'' contains two Nothospecies: ''H.'' × ''joerstadii'' and ''H. pubescens'' × ''tomentosum''. ''H. annulatum'' has three distinct subspecies.

''Adenosepalum'' is made up of primarily perennial herbs, and also includes shrubs and shrublets. Its species grow to be approximately 2.5 meters tall, and are generally deciduous. Species in ''Adenosepalum'' are glabrous or have simple hairs, and almost always have dark black glands on their leaves, sepals, and rarely on their petals and stems. Their leaves are placed opposite and have no ventral glands. Their flowers are stellate or homostylous. They have 5 sepals, 5 stamen fascicles, and 5 petals.<ref name="Hypericum MySpecies"/> {| class="wikitable mw-collapsible " |- ! Binomial !Common name ! Type ! Distribution ! Image !

==Sect. ''Brathys''== ''Brathys'' (Mutis ''ex'' L.f.) Choisy is the largest section in ''Hypericum''. It is divided into four subsections: ''Brathys'', ''Phellotes'', ''Spachium'', and ''Styphelioides''. ''Brathys'' contains 38 species and the type species, ''H. juniperinum''. ''Phellotes'' contains 32 species, ''Spachium'' contains 14 species, and ''Styphelioides'' contains just 2 species. In total, the section contains 86 species.

''Brathys'' contains a wide variety of plants, including small trees, shrubs, shrublets, and herbs. The largest species in the section grow to be 6 meters tall, and are evergreen. Its species are glabrous—though a few have simple hairs—and lack any dark glands. Their stems are either 4 or 6–lined, and are compressed when the plant is young, but later become terete. Their leaves are placed opposite, are decussate and sessile, and have dense marginal glands. All the species have either one flower on the uppermost node of the plant or 2–15 flowers branching from the uppermost node and from lower secondary nodes. The flowers are stellate or sometimes obconic, and are homostylous. The species have 5 petals which are persistent. They have 5 stamen fascicles which contain anywhere from 1–50 stamens each, formed in a tight ring, to give the plants a total of anywhere from 5–250 stamens. The plants have 5 ovaries, 5 sepals, and 3–5 styles.<ref name="Hypericum MySpecies"/> {| class="wikitable mw-collapsible " |- ! Binomial !Common name ! Type ! Distribution ! Image !

== Sect. ''Humifusoideum'' == ''Humifusoideum'' R. Keller, also called ''Pulogensia'', contains 6 species. Its type species is ''H. peplidifolium''. ''H. beccarii'' has two subspecies: ''H. beccarii beccarii'' and ''H. beccarii steenisii''.

Sect. ''Humifusoideum'' contains shrubs, subshrubs, and herbs that grow erect or prostrate and grow up to 1.5 meters tall. The shrubs are evergreen and glabrous and usually have dark glands. The stems are either 2-lined or 4-lined and are flattened when the plant is young, they usually lack glands, but rarely have dark glands; they are colored cortex greed or a dark red, while the bark is smooth and colored red-brown. The leaves are placed opposite, are decussate and free, and their blades are entire and either closed or open, with pale glands. The species usually have one flower, but very rarely can have up to ten that come from two nodes. The flowers are stellate and homostylous and have five free sepals that are persistent, five petals that are persistent and spreading, and three to five stamen fascicles with anywhere from ten to eighty stamens. The seeds are cylindric.<ref name="Hypericum MySpecies" /> {| class="wikitable mw-collapsible " |- ! Binomial !Common name ! Type !

== Sect. ''Hypericum'' == ''Hypericum'', sometimes referred to as the "type section" of the genus, contains perennial herbs and very few subshrubs. It contains the type species of the genus, ''H. perforatum''. Subsect. ''Erecta'', with twenty-three species, is the far less studied subsection of the section, while the details of subsect. ''Hypericum'' have been much more analyzed. Subsect. ''Hypericum'' has eighteen species total, with ten (including the type species) in ser. ''Hypericum'', and eight in ser. ''Senanensia''. The section contains forty-one species in total.

The species in sect. ''Hypericum'' grow to be 1.2 meters tall and can grow either erect or prostrate. They are glabrous some have dark glands while others do not. Their stems are 2-lined or 2-winged when young and either remain so or become terete as the plant ages. The leaves are placed opposite or abnormally whorled, are decussate, and are either sessile or pseudopetiolate, as well as being free and persistent. They are up to 70-flowered from one to four nodes, with some lower subsidiary branches. The flowers are stellate and homostylous. The species have 5 persistent sepals, 3 stamen fascicles, and 20–100 total stamens.<ref name="Hypericum MySpecies" /> {| class="wikitable mw-collapsible " |- ! Binomial !Common name ! Type !

== Extinct == ''Hypericum'' fossils have been found from the Late Eocene to the present day, with the most commonly found part of the plant being the seeds due to their hardiness. However, a small number of leaves and even pollen have also been found as fossils. The oldest fossil recovered was a seed belonging to the species ''H. antiquum'' which was found in Northern Asia. This species is considered to be the common ancestor of the family Hypericaceae.<ref name=":19">{{Cite journal|last=Meseguer|first=Andrea|date=March 2015|title=Integrating Fossils, Phylogenies, and Niche Models into Biogeography to Reveal Ancient Evolutionary History: The Case of Hypericum (Hypericaceae)|journal=Systematic Biology|volume=64|issue=2|pages=215–232|doi=10.1093/sysbio/syu088|pmid=25398444|pmc=4380036}}</ref> {| class="wikitable mw-collapsible " !Binomial !Fossil Status !Temporal Range !Location !Distribution !References |- |''H. antiquum'' Balueva & Nikitin |Seeds |{{Geological range|Neogene}} |Russia (Siberia) | |<ref name=":19"/><ref name=":79">{{Cite web|url=http://fossilplants.info/genus.htm?id=D2050ABE-168A-49DA-949B-598C4A943B1F|title=Hypericum: Nomenclatural Status|website=fossilplants.info|access-date=2018-09-28}}</ref><ref name=":7"/> |- |''H. canatalense'' E.
