Cytinus hypocistis L. - syn. Asarum hypocistis L. (basionym) - Cytinaceae - **Cistenräuber**

Ant-pollinated parasitic plant, native to the Mediterranean. 

"Cytinus hypocistis (L.) L. and C. ruber (Fourr.) Fritsch. are perennial holoparasites that appear exclusively on roots of Cistaceae species. The vegetative body of both parasites is contained entirely within the root of their host plants, and only in spring do the inflorescences burst through the host tissues." \\

"Male and female flowers of Cytinus, during both the day and night, produced a sweet scent (to the human nose) with [[http://www.thegoodscentscompany.com/data/rw1040881.html|(E)-cinnamyl alcohol]], [[http://www.thegoodscentscompany.com/data/rw1092691.html|(E)-cinnamaldehyde]] and 4-oxoisophorone predominating in the volatile profile... Most importantly, the presence of the main compounds was constant across all Cytinus populations and races, a finding that suggests they are important signalling molecules. Supporting this idea, our results have shown that volatiles released only by the flowers, and particularly (E)-cinnamyl alcohol and (E)-cinnamaldehyde, play an important role in the attraction of pollinators to Cytinus flowers." \\
