[explorer.natureserve.org] Range: Endemic to California, Lewisia serrata is known from approximately eleven occurrences in El Dorado and Placer Counties. However, five of the occurrences are historic and need to be surveyed for up to date information. Horticultural collecting and small hydroelectric power projects are threats to this species.
