Richardia brasiliensis Gomes e Diodia radula (Willd.) Cham. & Schltdl. are species of Rubiaceae belonging to the tribe Spermacoceae which has taxonomic and phylogenetic problems. The present work was an attempt to reveal structural and ontogenetic characters of the flowers and fruits of both species, which could be useful in the taxonomy of the tribe. Flowers and fruits at different stages of development were analyzed according to usual techniques in plant anatomy. Characters such as sepal structure, gynoecium morphology, mericarp number and morphology, exocarp pubescence, septum structure and sclerenchyma structure on the adaxial surface of the carpel can be interesting in the characterization of genera and species of the Spermacoceae tribe.
