The third anther, as we go up, is midway between the short stamens and the long ones, and thus the flower has three chances of dusting the insect with pollen ; first, with the tallest anthers, second, with the middle anther, and third with the lowest anthers. Even now we have not seen the whole of the plan for dusting the insect with pollen ; for if you take a riper flower that has the pollen-cases open, you will see that the pollen is always shed towards the.
