Lilium pensylvanicum, sometimes called Siberian lily, is a plant in the family Liliaceae, native to Siberia, Mongolia, northeastern China, Korea, Sakhalin, the Kuril Islands, and Hokkaido. The Latin epithet is misleading: it suggests a North American origin (Pennsylvania), but this stems from an error made by the botanist John Bellenden Ker. In 1809, Ker published a corrigendum in which he attempted to rename Lilium pensylvanicum as Lilium dauricum, after Dauria, a region near Lake Baikal. This renaming engendered considerable confusion and was subsequently formally rejected. Cultivated for its striking flowers, Lilium pensylvanicum serves as a popular ornamental plant.
