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]
Four species are accepted: [1] [3] [4]
