Abstract
Bauhinia thailandica, a new species in the tribe Cercideae, subfamily Cercidoideae in the Leguminosae collected from the Northeast of Thailand, is described and illustrated. It is similar to B. acuminata and B. hirsuta but easily distinguished by their habits, indumentum, floral bud, hypanthium, petal and bud. The distinguishing characters of these three species are discussed. A key to Bauhinia species in Thailand is included.
