Toxicopueraria peduncularis (Graham ex Benth.) A.N.Egan & B.Pan bis is reported for the first time in Thailand. Genus and species
descriptions are provided, along with vernacular names, distributional data and specimens examined. This Thailand population is
shown to be a distant outlier from the known range for T. peduncularis and its closely related sister species, T. yunnanensis in
Yunnan, Sichuan and Guizhou, China.
