Based on morphological evidence, the new species is placed in Lysimachia subgenus Idiophyton and diagnosed against its closest congener, L. nutantiflora. A revised key is also provided to distinguish L. longiracemosa from the related frutescent species with racemose inflorescences of the Lysimachia subgenus Idiophyton. %M doi:10.6165/tai.2026.71.32
