hedge-mustard; a genus of the filiquoza order, belonging to the tetradyamina clas of plants. There are six species, of which the most remarkable is the officinale, hedge-mustard, or bank-crestes. It grows naturally in Britain under walls, by the sides of highways, and among rubbish. It is warm and acrid to the taste; and when cultivated, is used as a vernal pot-herb. Birds are fond of the seeds; sheep and goats eat the herb; cows, horses, and swine refuse it. Some medical virtues have been attributed to the leaves, but these appear to be without foundation.
