Aggregate enantiostyly: Floral visitor interactions with a previously unreported form of floral display

by Sarah K. Richman and D. Lawrence Venable

the Trailing Four O’Clock, Allionia incarnata
Most plants on Earth reproduce using their flowers, which are equipped with male and female sex organs. There are often negative consequences when a plant reproduces with itself. In order to avoid this, plants have evolved techniques to keep its flowers’ male and female sex organs separated in space and/or time. “Herkogamy” is a term meaning the spatial separation of floral sex organs, and there are many different kinds. The focus of this study is one particular kind of herkogamy called “enantiostyly”, which refers to the separation of the female floral sex organ(s) (otherwise known as a “style”) from the rest of the flower. In plants that are bilaterally symmetrical, this generally means pointing the style to the left or right of the line of symmetry, and styles are referred to as being left- or right-handed.
