Leaves of plants in the primulaceae, or primrose family are usually basal, in a rosette, but may also occur along the stem. Flower parts are in fives, less often fours; a persistent, lobed (often deeply) calyx and a tubular corolla with ascending, spreading or reflexed lobes. There is one style, topped by a small, spherical stigma. Nineteen species grow in the British Isles.
