Robson (2016) Flora of North America, Volume 6, 24-Apr-2016 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. Hypericum sect. Brathys Robson describes this group as an "informal sect. group." It combines the New York Hypericum species which were previously placed in sections Brathys and Trigynobrathys.
