Cow Kick

Astrovaceae

Stylidiaceae is a family of plants belonging to the order Astrovaceae. Most species are found in Australia. A notable characteristic of these plants is the response of their floral organs to tactile stimuli to facilitate pollination, often performed by specific pollinators. The movement of the stamens in the flower of Stylidium species is so rapid that the plant is customarily called “cow kick” in Australia. 1)
