Resumo: 	The palynology of the following 16 species of Rubiaceae, from Brejinho das Amestistas, was investigated: Coccocypselum hirsutum Bartl. ex DC., Cordiera rigida Kuntze, Coutarea hexandra K.Schum., Declieuxia fruticosa Kuntze, Diodella apiculata (Willd. ex Roem. &amp;amp; Schult.) Delprete, D. radula (Willd. ex Roem. &amp;amp; Schult.) Delprete, D. teres Small., Emmeorhiza umbellata K.Schum., Leptoscela ruellioides Hook. f., Mitracarpus baturitensis Sucre., Mitracarpus villosus Cham. &amp;amp; Schltdl., Palicourea rigida Kunth, Psyllocarpus asparagoides Mart., Richardia grandiflora Steud., Staelia aurea K. Schum., and Staelia galioides DC. The pollen grains were acetolysed to and their morphological characters were analyzed using light and scanning electron microscopy. They varied in size from small to large; were suboblate to subprolate; inaperturate (P. rigida), colpate and colporate in the remaining species, with an aperture number that varied from three to several. The exines were microreticulate in most species, reticulate (C. hirsutum, C. rigida and P. rigida), bireticulate (D. fruticosa), microechinate-perforated (C. hexandra), echinate-granulate (R. grandiflora), echinate-granulate-perforate (D. apiculata and D. teres), and psilate (P. asparagoides). Based on the results, palynological data can be used to distinguish these species.
