Abstract

Hibiscus trionum, like several other members of the Malvaceae, has flowers with prominent styles which can reflex during the first few hours after opening so that stigmas make contact with the anthers. This self-pollination mechanism can be interrupted if stigmas are pollinated before or during bending. They then maintain or regain the erect position and selfing cannot occur. Various treatments which can affect this reversal of bending are described.
