Cytinus
Cytinus is a genus of parasitic flowering plants. Species in this genus do not produce chlorophyll, but rely fully on its host plant. Cytinus usually parasitizes Cistus and Halimium, two genera of plants in the family Cistaceae. It has also been found on Ptilostemon chamaepeuce.
Several species are found in the Mediterranean Region, South Africa, with a possibly undescribed species from Madagascar.
