Abstract
Lysimachia longiracemosa, a new species of Primulaceae, is described from the margin of highland subtropical broadleaved forests in southeastern Yunnan, China. 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.
