Some names used by Bean have now been superseded and are no longer familiar. To ensure that all plants can be easily found, under any name, we have cross-referenced to The Plant List, a collaboration between RBG Kew, Missouri Botanical Gardens and other organisations, which aims to provide a currently accepted name for any plant. Not all taxonomists will agree with all Plant List nomenclature, but it provides a baseline to compare names. For each species above, clicking on the Modern Name will link to the entry for that name on The Plant List website.
