Adenia is a genus in the passionflower family Passifloraceae. It is named after Aden, a city in Yemen[1].

The genus includes a number of tropical and subtropical xerophytes; many of which form substantially thickened bases or lianas. It is also a Caudiciform. Many species are characterised by the extreme toxicity of the sap. In addition to cyanogenic compounds, these contain lectins which destroy ribosomes, hence prevent protein synthesis. This is the same mode of action as ricin, and the toxicities are comparable. A. volkensii was shown to be intensely toxic by Barbieri (1984). Pelosi et al. (2005) compared ten species, and found 3 (A. stenodactyla, A. goezii and A. lanceolata) which were inhibitory at <0.1 ng/ml and lethal to mice at <2 ug/kg, making them among the most potent plant toxins known.
