''Galphimia gracilis'' is easily told apart from the true ''G. glauca'' and ''G. brasiliensis'' by the flowers. In ''G. gracilis'' the petals fall as the fruit matures; in ''G. glauca'' the petals are persistent even in fruit. In ''G. gracilis'' many flowers of a dense inflorescence are open at one time, and the petals (claw and limb) are long and wide; in ''G. brasiliensis'' only two or three small flowers are open at one time on a sparse inflorescence, and the petals are only long and ca. wide. Pollens are spherical, approximately 16-18 microns in diameter.
