Species 3 (3 in the flora).
Jepsonia is characterized by heterostylous flowers that are produced in the autumn after summer drought; some flowers have long styles and short stamens; others have short styles and long stamens. The floral differences associated with heterostyly within populations in this genus are part of an incompatibility mechanism that prevents self-fertilization. Leaves appear after flowering and persist through the winter if moisture is available. Rarely, leaves and flowers are present simultaneously. All three species of Jepsonia also produce a secondary taproot each year. This structure begins to grow after seasonal rains and shrivels before flowering begins. It apparently acts as a contractile root. The three species in this genus are narrow allopatric endemics.
