Peppergrass is common everywhere along roadsides and in fields from the West Indies and the Gulf States northward to Minnesota and Quebec. It is known by every schoolboy in the land, who has nibbled its peppery buds and seed cases, time and again. The plant is somewhat similar to the Shepherd's Purse, but is more branching, and the seed-pods are set closer and less sprawling on the stems. The upper part of this plant is more leafy, and the colour is possibly a paler green. The leaves of the basal rosette are less divided and more paddle-shaped with their edges nearly all toothed. The four white petals of the minute flower are often wanting. The flat, notched, scalelike seed-cases are loosely arranged around the ever-lengthening flower stalk, and they graduate finely into the few flowers and buds at the tip.
