Pterodon (plant)

Pterodon is a genus of flowering plants in the legume family, Fabaceae. It includes four species of trees native to Brazil and Bolivia. Typical habitats include seasonally-dry tropical forest, woodland (cerrado), and thorn shrubland (caatinga), often on rocky outcrops.^[1] It belongs to the subfamily Faboideae.

Pterodon can be distinguished from other members of the Dipterygeae as follows:

the leaf rachis is exalate, the fruit is a cryptosamara with oil glands in the epicarp, the seed testa is smooth and the raphe is apparent, with the hilum in a lateral position covered by an aril and a smooth embryo.^[2]
