SHEPHERD'S PURSE.
Capsella Bursa-pastoris, Medic. Mustard Family.
Among our commonest and most harmless weeds is the shepherd's purse, which has been introduced from Europe in the past. It may be easily recognized by its tiny white cruciferous flowers and its shapely little triangular, flat pods, which have a peppery taste. It is used medicinally, and valued as a remedy for many different maladies. In Europe, a common name for the plant is "mother's heart," and Mr. Johnston says that children play a sort of game with the seed-pouch. "They hold it out to their companions, inviting them to 'take a haud o' that.' It immediately cracks, and then follows a triumphant shout, 'You've broken your mother's heart!'"
Equally common is the Lepidium, or pepper-grass, the small round, flat pods of which also have a peppery taste. Both of these belong to the great Mustard family.
