Throughout China [India, Indonesia, Nepal]

Lycianthes lysimachioides is a highly variable species, and the varieties recognized here are weak taxonomically and might well be placed in synonymy under the type variety. A series of infraspecific taxa recognized in FRPS (L. lysimachioides var. purpuriflora C. Y. Wu & S. C. Huang, L. lysimachioides var. [unsupported code]osana Bitter, L. lysimachioides var. rotundifolia C. Y. Wu, L. lysimachioides var. cordifolia C. Y. Wu), none of which compete in priority with the names used here, may have taxonomic validity, but this cannot be perceived at this time.
