Distyly is a complex morphological and physiological polymorphism - the two floral morphs of a distylous species produce flowers that differ reciprocally in style and stamen lengths, and both self- and intramorph fertilizations are partially or completely prevented by self-incompatibility (Ganders 1979; Barrett 1990).
