Male and female floral structure has been studied in 28 species of Chamaedorea, the largest palm genus present in the Neotropics. The taxa investigated represent all subgenera according to the most recent taxonomic revision of the group. Morphological, histological and cytological features that are known to be of importance for interactions with visiting insects were studied and their putative role in protecting the flowering parts assessed. The taxonomic distribution of selected characters is in some cases congruent with relationships inferred by recently published molecular studies within the group.
