'''''Adenia''''' is a genus in the passionflower family Passifloraceae. The genus includes a number of tropical and subtropical xerophytes; many of which form substantially thickened bases or [[liana]]s. 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&nbsp;ng/ml and lethal to mice at <2&nbsp;ug/kg, making them among the most potent plant toxins known.
