Hypericum is a genus of flowering plants in the family Hypericaceae. 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 TriadenumRaf.
Hypericaceae is a plant family in the order Malpighiales, comprising six to nine genera and up to 700 species, and commonly known as the St. John's wort family.

Jane Colden was an American botanist, described as the "first botanist of her sex in her country" by Asa Gray in 1843. Although not acknowledged in contemporary botanical publications, she wrote a number of letters resulting in botanist John Ellis writing to Carl Linnaeus of her work applying the Linnaean system of plant identification to American flora, for which botanist Peter Collinson stated "she deserves to be celebrated". Contemporary scholarship maintains that she was the first female botanist working in America, which ignores, among others, Maria Sibylla Merian or Catherine Jérémie. Colden was respected as a botanist by many prominent botanists including John Bartram, Peter Collinson, Alexander Garden, and Carl Linnaeus. Colden is most famous for her untitled manuscript, housed in the British Museum, in which she describes the flora of the Hudson Valley in the Newburgh region of New York state, including ink drawings of 340 different species.
