heterostyly
Quick Summary
Heterostyly is a fascinating botanical trait that promotes cross-pollination in flowering plants. It is characterized by variations in the length of the style, which is the part of the pistil connecting the stigma to the ovary.1
This structural difference in style length creates distinct flower forms. For example, in some species, one form has short stamens and a long style, while another form has long stamens and a short style. This arrangement makes it difficult for pollen from a flower to pollinate its own stigma, thereby encouraging pollination by different plants. This mechanism is crucial for increasing genetic diversity within a species, which can be advantageous for survival in changing environments.1
