The large, attractive magenta or purple red flowers of this terror of the wheatfields are pretty well known throughout the length and breadth of the land. It is an immigrant from Europe, and as Theodore Roosevelt would say, it is an "undesirable citizen." It is despised by grain-growing farmers, who everlastingly condemn and destroy it. It is an erect, leafy annual, growing from one to three feet high, and is thickly covered with closely adhering, whitish hairs. The long, narrow, pointed leaves measure from one to four inches in length, and a quarter of an inch or less in width. It is occasionally branched. The showy flower has five broad, rounding, flaring petals, alternating with an equal number of long, narrow leaflike sepals, which extend far beyond the corolla. It has ten stamens and five styles. The latter alternate with the calyx lobes, and are opposite the petals. The flower is borne singly on long, stout stems, and produces numerous rough, black, poisonous seeds. It is found frequently or occasionally from July to September, throughout its area, but most commonly in the Central and Western States. It may be found in many sunny, waste places, but is scarce in the dry region from California to Texas, and eastern Kansas. The United States Government classes the Corn Cockle among our principal poisonous plants, the dangerous qualities of which are contained in a soluble and odourless powder, called saponin. It possesses a sharp, burning taste, and provokes violent sneezing if inhaled in the smallest quantity. When agitated in water, it foams like soap. The objectionable element is found in all parts of the plant. The most harmful results occur from eating bread made from flour containing the seeds which have been ground up with the wheat, and its continued use will cause serious chronic disorders. Low grades of flour often contain large quantities of Corn Cockle seeds, which can easily be detected by the presence of the black, roughened scales of the seed cases. Several machines have been invented for removing these dangerous seeds from the wheat, but as yet, none has been altogether successful. In New Hampshire, Corn Cockle is known as Old Maid's Pink, and in Nova Scotia it is called Mullein Pink, while the American farmer ever longs for a name that will fully express his contempt for it. The Latin name, Agrostemma, signifies "Crown-of-the-Field."
