Myristicaceae consist of 21 genera and nearly 500 species of lowland rainforest trees with a pantropical distribution. This article presents new scanning electron microscopy observations on pollen of 13 genera, including all Asian genera, which had previously received very little attention from palynologists. While confirming that all Myristicaceae have monoaperturate pollen shed as monads with a sculptured aperture membrane, this study increases our knowledge of the diversity of pollen shapes, aperture shapes, tectal sculpture and microsculpture, and infratectal structure across the family. It also clarifies a few characters in previously investigated Afro‐Malagasy taxa. These results are discussed in the context of a recent phylogenetic study. While several pollen characters appear to be homoplastic, aperture shape, tectal sculpture, and infratectal structure seem to be of great phylogenetic value in Myristicaceae and clearly distinguish an Afro‐Malagasy clade of five genera (including Mauloutchia) from...
