Recent investigations into the toxicity of plants, etc. XIII

Abstract

Of the twenty-two plants investigated, six were, for the first time, proved to be toxic, namely Boscia foetida Schinz., Cadaba juncea (Linn.) B. & H., Othonna cluytifolia O.K., Drimia alta R. A. Dyer, Scilla natalensis Planch, and Jasminium angulare Vahl. The results obtained from experiments with Berkheyopsis echinus (Less) O. Hoffm. and B. bechuanensis S. Moore, Glircida maculata H.B.K. and Datura arborea L. are not considered to be conclusive. The pupae of Acanthopsyche junodi Heyl were found to be non-toxic whereas the larvae of Laphygma exempta Walker proved to be poisonous. Waste porridge from compounds was proved to be the etiological agent in an outbreak of poisoning in cattle.
