Summary A palynological study of Achatocarpus Triana and Phaulothamnus A. Gray utilizing structural data from transmission electron microscopy (TEM), reinforces their close relationship as suggested by scanning electron microscopy (SEM) and supports family status as Achatocarpaceae. Both genera are known to have the betalain pigments and protein‐type sieve tube plastid which characterize the order Centrospermae. Affinities within the Centrospermae remain uncertain.
