Many species lack both stems and leaves; photosynthesis takes place instead in a highly modified, ribbonlike thallus (vegetative plant body. The genus Hypericum is organized here into sections as treated by Robson (). The name Hypericum was derived from the Greek hyper (above) and eikon (picture), possibly indicating that the flowers of these plants were hung above pictures or windows.
