Discussion

Prior to recognition of the North American Lysichiton as a distinct species, the genus contained a single taxon, L. camtschatcensis. This name (in several spelling variations) was previously applied to both Asian and American Lysichiton and is now the valid name for Asian populations. Asian and American plants differ primarily in spathe color, with L. camtschatcensis having white spathes and L. americanus, with yellow spathes.

Species 2 (1 in the flora).
