Abstract The phylogeny of suprageneric groups inCyperaceae has been examined by cladistic analysis ofrbcL sequence data of 80 species in 40 genera. The results support the family as monophyletic and derived from a juncaceous grade.Oxychloe (Juncaceae) has moderate support as the sister taxon toCyperaceae. Several monophyletic groups correspond to previously recognised tribes, and some similarities are noted between this analysis and previous cladistic analyses of primarily morphological data. Support is also given for the removal ofHellmuthia from tribeHypolytreae, the transfer ofIsolepis nodosa toFicinia, and the inclusion ofOxycaryum andKyllingiella in tribeCypereae. A polytomy comprisingCyperus, Juncellus, Kyllinga andPycreus indicates a broader circumscription ofCyperus. The greatest uncertainty lies with the generic and tribal status of theScirpeae.
