Recent investigations into the toxicity of known and unknown poisonous plants in the Union of South Africa. XII

Abstract

The toxicity of fourteen plants was investigated. According to the available literature the following plants, viz., Mesembryanthemum angulatum Thunb., Kalanchoe rotundifolia Harv. and Urginea rubella Baker have for the first time been proved to be toxic. The results of the experiments with the fungus-infected mangolds and Scilla oratifolia Baker form. cannot be considered conclusive. Poinciana pulcherrima L. was shown to be a cyanogenetic plant and it was proved that Ornithogalum thyrsoides Jacq. is capable of causing blindness.
