Detailed information on the character states of Pseudopyxis depressa and P. heterophiylla , the only two representatives of the genus, are given. Particularly remarkable are the occurrence of both homo‐ ( P. heterophiylla ) and hetero(di)styly ( P. depressa ) and associated palynological differences, and the unusual fruits and diaspores, whose development is documented. Relationships between the two species are also discussed, and a section on the taxonomic position and history of the genus is included.
