Look at the flower in the second picture, it does look very much like the Bauhinia we have there, but the leaves are different. My hometown is in SW Guangdong, where there are many Bauhinia trees. Pay attention to the pictures inside the wikipedia link posted downstairs, the first picture of the Bauhinia, its leaves are divided into two petals, which we jokingly called butterfly leaves when we were kids, and the middle of the leaf is concave, while in the picture you posted, the very bottom of the leaf is protruding out of the tree. Therefore, it can be concluded that the tree is not a Bauhinia (Bauhinia spp.), while the leguminous Bauhinia in the second article has no leaves in the picture, and the flowers don't look like the same kind, so it's not easy to tell if it's a leguminous Bauhinia or not.

Sumacaceae Bauhinia, we have always called Bauhinia, never knew that the original scientific name is Bauhinia, really learn!
