Sequences of the trnS-trnG noncoding region chloroplast DNA from 40 species of the Zamiaceae and Stangeriaceae families and 3 out group species (Cycadaceae) were used to reconstruct phylogenetic trees using distance and parsimony methods. The distance tree was similar in topology to the parsimony tree and both indicated that Encephalartos had a relationship closer to Lepidozamia than Macrozamia. Encephalartos, Lepidozamia and Macrozamia comprised a monophyletic tribe, while Dioon was a basal-sister of the subfamily Encephalartoideae clade. These two analyses also revealed a close relationship between Microcycas and Zamia with high bootstrap support. Although Stangeria and Ceratozamia have been placed in different families, they were closer to each other, rather than Bowenia which is contrary to previous morphologically based classifications. The current study provides new molecular evidence that Stangeria and Bowenia are not sister taxa and reinforces the close relationship between Encephalartos and Lepidozamia.
