Notes:
Abstract TheIrvingiaceae generally possess large intrastaminal receptacular disc nectaries of the mesenchymatic histo-type, which receive numerous small phloematic bundles directly from the central stele. The non-glandular epidermis bears some 10 to 15 strictly localized stomata that are deeply sunken in the parenchyma. The nectar is assumed to be exposed on the disc surface. Flowers are of simple construction, lacking specialized organs to attract pollinators. A wide range of pollinators is thus expected. TheIrvingiaceae have more characters in common withSimaroubaceae thanIxonanthaceae and should therefore be retransferred as a family of their own next toSimaroubaceae.
