Toxicological investigations were conducted on galenia [Galenia pubescens (Eckl. and Zeyh.) Druce], an introduced species of the family Aizoaceae. One lot of field-grown galenia assayed 2.5% nitrate (as KNO3) and 6.1% soluble oxalates. Three sheep were acutely poisoned after they were gavaged with this plant. Galenia grown in nutrient solution assayed 6% nitrate and 11.3% soluble oxalates. Chicks fed this material died of nitrate and oxalate poisoning. Galenia may accumulate toxic levels of both oxalates and nitrates and thus should be classed as a poisonous plant that would be considered hazardous to humans and livestock.
