World's fastest plant
Canada's bunchberry dogwood is the fastest plant on the planet. The flower pops open in less than 1/2 millisecond to fire off its pollen, reports scientist Joan Edwards and her colleagues from Williams College and Oberlin College in this week's issue of Nature. From Discovery Channel News:
Link (Thanks, Bhuvana Iyer!)"Bunchberry stamens are designed like miniature medieval trebuchets — specialized catapults that maximize throwing distance by having the payload attached to the throwing arm by a hinge or flexible strap," Edwards said.
The trebuchet allows the flower to throw pollen further than a simple catapult would, she said.
UPDATE: BB reader Jon smartly suggests that botanist Joan Edwards (hopefully) meant "evolved" not "designed" in her quote above!
