What is "smodingium"

The African poison ivy (Smodingium argutum) is a southern African shrub or medium-sized tree in the Anacardiaceae, which has properties comparable to the American poison ivy, as its sap contains heptadecyl catechols that are toxic to the skin. An immuno-chemical reaction is suspected as in other toxic anacardiaceous species. It is monotypic in the genus Smodingium, and was discovered in Pondoland by J. F. Drège during an 1832 expedition with the zoologist Andrew Smith.
