Authors: Dezhao Chen, Prof. Dianxiang Zhang, Kai Larsen, Supee Saksuwan Larsen & Michael A. Vincent

Leaves alternate, simple, entire or 2-lobed, sometimes parted to base, divided and 2-foliolate. Flowers usually bisexual, rarely unisexual (polygamous or plants dioecious), slightly or conspicuously zygomorphic. Calyx entire, 5-toothed, spathaceous or val­vately 2-5-lobed. Petals usually (2-)5(or 6), subequal to greatly unequal, free. Perfect stamens 10 or 2-9 reduced to staminodes; anthers dorsifixed, opening lengthwise or by apical pores. Ovary stipe free or adnate to receptacle; ovules 1 to numerous. Legumes flattened or turgid.

About five genera and 320-350 species: four genera represented in tropical regions, one in temperate parts of the N Hemisphere; two genera and 52 species (28 endemic, two introduced) in China.

The concept of the genus Bauhinia as presented here is adopted in the broadest sense.

+ Legume without wings; perfect stamens usually 3 or 5, if 10 then flowers white, light yellow, or green.   2 Bauhinia
