Flowers regular, symmetrical, and perfect; perianth hypogynous. Calyx persistent. Corolla rotate, hypocrateriform, or campanulate.

    The only other plant of this order in our Materia Medica is the European Sow - Bread (Cyclamen Europaeum, Linn.). In general and household practice the flowers of the European Cowslip (Primula officinalis, Jacq.) have been used as a sedative, and placed in wine to render it soporific.

    History and Habitat. The Pimpernel is naturalized in this country from Europe, and has established itself along both the Atlantic and Pacific coasts in dry, sandy soil, where it blossoms from June to August.
