Corn-cockle

Corn-cockle (Agrostemma Githago), a tall beautiful caryophyllaceous weed, well known on account of its large purple flowers. It is often so common in cornfields as to be mischievous, especially on the Continent, and this not only because of its rankness and abundance, but also because of the deleterious nature of its seeds, which are injurious to man and poisonous to most domestic animals, and which sometimes require to be separated from the grain by a special kind of sieve.
