Cassytha is a (hemi)parasitic genus of Lauraceae with its main diversity in Australia. To characterise a new species from Gabon, we studied and revised the African species of this genus. Previously 3 or 4 taxa were recognised to occur in Africa, in this study we recognise 5 species; next to our new species we resurrect Cassytha schliebenii to species level. The new species, Cassytha graminicola, is parasitising on monocotyledons, especially grasses, and is likely the first recorded annual among the Lauraceae. Cassytha paradoxae from the New World also seems to use monocotyledons as host, and should be recognised as a valid species.
