Resumo
The palynological morphology of 24 species and two subspecies of Stillingia were studied using scanning electron microscopy. The analysis was performed aiming to verify whether the pollen morphology can be helpful for identifying species and infrageneric categories in this group. Pollen grains of Stillingia are subprolate or suboblate, tricolporate, microreticulate, and psilate along the aperture margins. However, the results showed no variation between the species and demystify the importance of pollen morphology in the definition of infrageneric limits. Thus, pollen data cannot be used to distinguish species groups despite contrary indications in the literature.
