Oxalic acid and oxalates occur in many plants. Consumption of plants containing high concentration of oxalates can be poisonous to animals. This has been reported by several investigators (5, 7, 9). However, in only a few plants are oxalates found in sufficient quantities to be lethal. Some species with a relatively high oxalate content are: sorrel (Rumex spp.), rhubarb (Rheum spp.), greasewood (Sarcobatus vermiculatus Torr.), soursobs (Oxalis cernus Thunb.), and halogeton (Halogeton glomeratus C. A. Mey.).
