Fordia, Indo-Burma, ndo-China, new taxon, lectotypification


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 (Millettia
cana, M. puerarioides and M. velutina), and Laos (M. velutina). Lectotypes are designated for Millettia cana, M. multiflora, M. oraria and M. velutina. The full descriptions of Millettia cana and M. multiflora are provided for the first time based on fresh specimens.
