In this study, pollen grains of 74 taxa (84 specimens) of the Cryptocarya group, including 22 type collections, have been examined by scanning electron microscopy. Pollen grains of Aspidostemon, Endiandra, Hexapora, Potameia and Triadodaphne are described here for the first time. For the other genera (Beilschmiedia, Cryptocarya, Eusideroxylon, Potoxylon) the results of previous studies are largely confirmed, but a novel type of exine covered by clavate-baculate structures was found in a few Cryptocarya species (C. gracilis and C. macrodesme from New Caledonia, C. saligna from South America). A larger diversity of spinule morphology and density than hitherto known is documented among the African species of Beilschmiedia.

A phylogenetic analysis based on nuclear ITS and plastid trnK intron sequences confirms that Dahlgrenodendron, Sinopora, Triadodaphne, and Yasunia are members of the Cryptocarya group, as expected from morphology.\  Dahlgrenodendron from South Africa is sister to Aspidostemon from Madagascar. Triadodaphne inaequitepala is nested within Endiandra (both from Australasia), and Yasunia from South America is nested among South American Beilschmiedia species. Sinopora is a member of the Beilschmiedia clade, but its precise position is still uncertain.\  Among large genera of the group, Cryptocarya is clearly monophyletic, and Endiandra appears to be as well, if T. inaequitepala is included. Beilschmiedia is paraphyletic with respect to (at least) Potameia and Yasunia. Most well-supported clades within genera are geographically homogeneous, except a clade including the Chilean Cryptocarya alba and two New Caledonian species. Both Beilschmiedia and Cryptocarya have reached the Americas more than once.\  Four-locular anthers are plesiomorphic in the Cryptocarya group; two-locular anthers have arisen by fusion of the two pollen sacs of a theca. In the plesiomorphic fruit type, the ovary is completely enclosed in receptacular tissue; a superior fruit, seated free on its pedicel, is a synapomorphy of the Beilschmiedia clade.
