Evolutionary changes in the breeding systems of heterostylous plants have been documented in several unrelated flowering plant families. Modifications include the replacement of one type of outcrossing mechanism by another, such as the evolution of distyly from tristyly in the Lythraceae (Lewis and Rao, 1971) and Oxalidaceae (Ornduff, 1972; Weller, 1976) and the origin of dioecism from distyly in the Rubiaceae (Baker, 1958) and Menyanthaceae (Ornduff, 1966a).
