The pollen morphology of seven species belonging to three genera of the Apocynaceae family and occurring in the state of Santa Catarina, Brazil, was considered in the present paper. The pollen grains of three species of Aspidosperma [A. australe Muell. Arg., A. pyricollum Muell. Arg. e A. ramiflorum Muell. Arg.] correspond to a same pollen type, and present no specific morphological features. Similar observation was made of the three species of Peschiera (Peschiera cf. australis (Muell. Arg.) Miers, Peschiera catharinensis (DC) Miers e Peschiera aff. histrix (Stend.) DC. Rauvolfia sellowii Muell. Arg. presents a characteristic pollen morphology of oblate and brevicolpate pollen grains. The occurrence of a vestibulum in the apertural area of the pollen grains is a attribute of all species examined.
