Anisostyly
Definition
A morphological phenomenon or characteristic of certain higher plants consisting of the inequality in length or shape of styles within the same flower or across different flowers belonging to the same species; heterostyly. This structural plant anatomical adaptation plays a crucial ecological role in preventing self-pollination and promoting cross-pollination via insects.
