Hypericaceae
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. Members are found throughout the world apart from extremely cold or dry habitats. ''Hypericum'' and ''Triadenum'' occur in temperate regions but other genera are mostly tropical. Characteristics Members of this family are annual or perennial herbs, subshrubs or shrubs. The leaves are simple and entire, in opposite pairs; they are sometimes dotted with black or translucent glandular spots. The inflorescence consists of a branched, flat-topped cluster, each flower being radially symmetrical, with a superior ovary. Flowers have the following components: sepals, four or five, which tend to persist; petals four or five, usually yellow, sometimes dotted with black specks; stamens many, on long filaments; styles, three to five, often fused at the base. The fruit has a dehiscent capsule which splits open when ripe to release th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triadenum
''Triadenum'', known as marsh St. John's worts, is a small genus of flowering plants in the family Hypericaceae. The genus is characterized by opposite, blunt-tipped leaves and pink flowers with 9 stamens. They are distributed in North America and eastern Asia. Acceptance of this genus is varied. Kew's Plants of the World Online and the Database of Vascular Plants of Canada (VASCAN) treat it as a junior synonym of ''Hypericum'' and the '' Flora of North America'' and ''Flora of China'' treat it as separate. The situation arises from B. R. Ruhfel et al. (2011)'s genetic study describing ''Triadenum'' as subsumed under ''Hypericum'' and later genetic results disagreeing with this assessment. Under ''Hypericum'', the species are mostly treated as the section ''Hypericum'' sect. ''Elodea''. Species ''Triadenum'' contains the following 6 species according to ''Flora of North America'' and ''Flora of China'': * '' Triadenum breviflorum'' (Wall.) * '' Triadenum fraseri'' * '' Triade ...

Malpighiales
The Malpighiales comprise one of the largest orders of flowering plants, containing about 36 families and more than species, about 7.8% of the eudicots. The order is very diverse, containing plants as different as the willow, violet, poinsettia, manchineel, rafflesia and coca plant, and are hard to recognize except with molecular phylogenetic evidence. It is not part of any of the classification systems based only on plant morphology. Molecular clock calculations estimate the origin of stem group Malpighiales at around 100 million years ago ( Mya) and the origin of crown group Malpighiales at about 90 Mya. The Malpighiales are divided into 32 to 42 families, depending upon which clades in the order are given the taxonomic rank of family. In the APG III system, 35 families were recognized. Medusagynaceae, Quiinaceae, Peraceae, Malesherbiaceae, Turneraceae, Samydaceae, and Scyphostegiaceae were consolidated into other families. The largest family, by far, is the Euphorbiaceae, ...

Hypericum
''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'' 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''. Description ''Hypericum'' species are quite variable in habit, occurring as trees, shrubs, annuals, and perennials. Trees in the sense of single stemmed woody plants are rare, as most woody s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clusiaceae
The Clusiaceae or Guttiferae Juss. (1789) (''nom. alt. et cons.'' = alternative and valid name) are a family of plants including 13 genera and ca 750 species. Several former members of Clusiacae are now placed in Calophyllaceae and Hypericaceae. They are mostly trees and shrubs, with milky sap and fruits or capsules for seeds. The family is primarily tropical. More so than many plant families, it shows large variation in plant morphology (for example, three to 10, fused or unfused petals, and many other traits). According to the APG III, this family belongs to the order Malpighiales. One feature which is sometimes found in this family, and rarely in others (e.g., Malpighiaceae), is providing pollinators with rewards other than pollen or nectar; specifically, some species offer resin which bees use in nest construction (all three rewards are found in different species of the Clusiaceae).
