Fifteen species belonging to five genera were found: Microstachys and Sapium, the most diverse, with nine and three species respectively, followed by Gymnanthes, Maprounea and Sebastiania with one species each. Sapium haematospermum is firstly recorded in the state of Goiás. Species identification key, species descriptions with comments and illustrations, besides the transference of Sebastiania anisodonta and S. salicifolia to the genus Microstachys and a lectotipification.

Keywords : diversity; flora of Cerrado; nomenclature; richness.
