Summary Helleborus argutifolius was proposed as a species distinct from H. lividus Aiton (1789) by Viviani in 1824. Some authors have treated it at subspecific rank, but only now is a subspecific epithet validly published in combination with the earliest available specific name. A new combination is also made at (notho‐)subspecific rank for hybrids between representatives of the two taxa. The remarkable discrepancy between H. lividus Aiton in Curtis (Jan. 1789) and H. lividus sensu Aiton, Hort. Kew. (Aug./Sept. 1789) is traced to an unacknowledged change of concept between the 6th and 7th editions of Miller's Gardeners Dictionary (1752, 1759). The nomenclatural status of the names applied to these plants by Schiffner (1889, 1890) and other authors is analysed.
