Quick Summary

The Stylidiaceae family, also known as the trigger plant family, comprises herbs and shrubs native to Southeast Asia, Australia, and South America. These plants are characterized by their simple leaves and flowers that have only one plane of symmetry. A distinctive feature of their flowers is a sensitive column of stamens that triggers an explosive release of pollen when touched by insects. The largest genus within this family is Stylidium, which includes many species that are cultivated as ornamentals. Some species within the Stylidium genus are also carnivorous.123
