| Stylidium alsinoides R. Br. |
Stylidium alsinoides, a triggerplant, is a dicotyledonous plant that belongs to the genus Stylidium (family Stylidiaceae). S. alsinoides is one of the few triggerplants that is not entirely endemic to Australia. It is native only to Northeast Australia, Queensland, and the Philippines.[1]
Pollination is achieved through the use of the sensitive "trigger" (a floral column, in which the stamen and style are fused) that snaps forward quickly in response to touch, covering the insect in pollen. All triggerplants can also be described as being protocarnivorous because the glandular trichomes that are just below the flower can trap and kill small insects, but cannot digest them, unlike a true carnivorous plant.[2] [3]
