The pollen of Boerlagiodendron , one of the most distinct genera of Araliaceae, is unique within the family in its remarkable degree of differentiation of sexine into pertectate and intectate patterns and in its reduced apertures. The unexpanded mesocolpia and the inconspicuous apertures have apparently caused misinterpretation of the pollen morphology of B. pectinatum in recent literature. A comparative study of several pollen features, together with the meristic characters of carpels and stamens, has demonstrated some significant correlations among them. It appears that the origin of the genus may have been centered around the New Guinea and Solomons areas.
