The modern conception of Androsaemum as a section within Hypericum was first created in Flore de France in 1847. It included H. hircinum and H. androsaemum, and had a description that noted its berries that dry out and split. [6] However, the status of Androsaemum as a section and not a genus was contested over the next century.
Hypericum androsaemum, the shrubby St. John's wort, is a flowering plant in the family Hypericaceae.Commonly called tutsan or sweet-amber, the species is cultivated as an ornamental plant because of its striking red-tinted foliage, bright yellow petals, and its large clusters of fruit.
Hypericum sect. Androsaemum, commonly called tutsan, is a section of flowering plants in the family Hypericaceae. It is made up of Hypericum androsaemum (its type species), H. foliosum, H. grandifolium, and H. hircinum, as well as the hybrid H. × inodorum. Members of the section are deciduous shrubs of medium size.
Hypericum / ˌ h aɪ ˈ p iː r ɪ k əm / is a genus of flowering plants in the family Hypericaceae (formerly considered a subfamily of Clusiaceae). [3] [4] The genus has a nearly worldwide distribution, missing only from tropical lowlands, deserts and polar regions. [5] Many Hypericum species are regarded as invasive species and noxious weeds.
The genus Hypericum contains a number of nothospecies, or hybrids created directly from crossing two accepted species to create an intermediate organism that shares properties of both. Many of these hybrid species are used as ornamental or decorative plants.
The genus Hypericum contains approximately 500 species which are divided into 36 sections as described by botanist Norman Robson. [2] 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.

The difference between the No. 6 seed and the No. 7, the latter of which would have to travel to Philadelphia on wild-card weekend, was massive. But it was costly. Watson went down with a bad ...
Thus, Hypericum hircinum was assigned to Hypericum sect. Androsaemum in 1985. [12] A 2013 study used Bayesian inference to establish the phylogeny and close relations of Hypericum species. Section Androsaemum, including Hypericum hircinum, was placed into an "Androsaemum-group" with several other sections.
