Here is one of the first photos to make it through the rather arduous digital editing process:

Note the bristle of hairs presented on the upper half of the lip. You might think (along with any self-respecting bee) that this is a cluster of stamens and/or pistils all covered in pollen and ready for the bees to collect (and thus distribute pollen between flowers), but you would think incorrectly. The true pollen is in the arrow-like structure (the column) arching downward from the center of the flower. The lip is jointed below the bristles, bending under the weight of the small bees that visit these flowers. This forces the bee onto its back onto the waiting column below. In the process, pollen is transferred to its back, to be picked up when it visits the next flower. Thus, this species of orchid uses trickery to achieve pollination, not offering any true reward (nectar or pollen) to the visiting bee. This strategy appears to be fairly successful, judging by the number of seed pods encountered on these plants in the wild.
Enjoy!
