|When plants attack...

Folks from Australia might consider this post about one of their common wildflowers to be quite dull, so I'll try to keep it interesting, I promise. Above you see one of the species of triggerplant (genus Stylidium), a rare 3-lobed corolla mutant (they typically have four corolla lobes–or "petals"–with a fifth highly reduced). It's column, the fused male and female reproductive organs, has been triggered by the pollinator rooting around in the corolla tube, searching for nectar. The column, which normally rests underneath the flower, springs forward in milliseconds, dusting the unsuspecting pollinator with pollen (or picking it up from an already dusted insect as the stigma takes over the column once pollen has been shed). This aids in cross-pollination.
