Abstract Thulin, M., L. Nusbaumer & L. Gautier (2014). Bauhinia darainensis Thulin & Nusb. (Fabaceae), a new species from northern Madagascar. Candollea 69: 135–139. In English, English and French abstracts. Bauhinia darainensis Thulin & Nusb. (Fabaceae), a new species from the Loky-Manambato region of north-eastern Madagascar, is described and illustrated. The species is believed to be most closely related to Bauhinia decandra Du Puy & R. Rabev. from south-central and southern Madagascar and Bauhinia hildebrandtii Vatke that is widespread in northern Madagascar. Bauhinia darainensis differs from both these species notably by its white petals, with the upper petal pink towards the tip, and by its stamen arrangement with three longer and seven shorter and more slender stamens. The distribution and ecology of the new species are discussed and a preliminary IUCN Red List conservation assessment is proposed.
