Hypericum Conjungens

	Norman Robson (botanist) Norman Keith Bonner Robson (1928 – 6 September 2021) was a Scientific Associate in the Plants Division, Department of Life Sciences at the Natural History Museum, London. He was a member of staff at the Museum from 1962–1988, retiring as Principal Scientific Officer with responsibility for General Herbarium Section I. Norman produced a worldwide taxonomic monograph of genus ''Hypericum'' between 1977 and 2012. Norman’s interest in ''Hypericum'' was stimulated by a final year project on the British species whilst at Aberdeen University. He continued work on the genus for his PhD at the University of Edinburgh (Robson, 1956) with a thesis entitled ‘Studies in the genus ''Hypericum'' L.’ that examined floral anatomy and evolution. At the Royal Botanic Gardens, Kew and subsequently at the Natural History Museum, Norman contributed accounts of Hypericum for Floras of various parts of the world. Roy Lancaster encouraged him to start work on a ''Hypericum'' monograph in the ea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	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]
