New species, new records and lectotypifications in Millettia are presented. Millettia densiflora, a new species discovered from Laos, is described and illustrated. Additionally, we provide a detailed morphological description, illustrations, colour plates, distribution map, phenology, conservation status and a discussion of its closest affinity. We further present first reports for Thailand (Millettiacana, M. puerarioides and M. velutina), and Laos (M. velutina).
