Toxicodendron Capense Thunb. (Fam. Eurphorbiaceae.)—The fruits of this South African species are said to be used for the poisoning of hyenas. They have been investigated by von Engelhardt (Kobert's Arbeiten, 1892), who finds in them a neutral, bitter principle, hyananchin, which is a powerful poison, resembling strychnine in its physiological action, from which, however, it differs in that it powerfully affects, the cerebrum. The convulsions which it produces are of central origin, the poison having no action upon the nerve trunks or the muscles.
