We examined pollen of all five species of Olinia , the only genus of Oliniaceae (Myrtales), an endemic African family. Olinia pollen is heteropolar with one pole colpate and the other heterocolpate. Restriction of pseudocolpi to one polar face, hence, half pseudocolpi, the inequality of the two polar faces, and the unequal distribution of the colpus segments across the modal plane, are features that distinguish Olinia from all other Myrtales.
