The yellow flowering herb sent from Glenroy1 is a Trefoil Sorrel, Oxalis corniculata, a perennial plant, wild in many parts of the globe. If it was consumed in large quantities by pasture animals it might be hurtful, as it contains oxalate of lime and of other alkalis, by which inflammation of the digestive tract might be set up. Indeed, human poison cases have exceptionally occurred from this herb. Generally, however, the Oxalis is occurring only mixed so sparingly with other foliage and with grasses that no harm is done by this plant. If It abounds anywhere, then the ground might be ploughed up and sown with the seeds of strong perennial grasses and fodder herbs, the upgrowth of which would suffocate the Trefoil Sorrel, and would simultaneously increase the carrying capability of the pasture.
