Pink Elephants



Day 310: I thought I was going to have to buy a gallon of cheap wine in order to see pink elephants this year, but thanks to my botany partners Joe and Sharon, I found where they were hiding. Yes, this is the Elephant-head Pedicularis I mentioned a few days ago. It tends to bloom earlier than most of the other Pedicularis species. Take a close look at the individual flowers on the spike. The elephants' trunks are obvious, but do you see the floppy ears as well?

Interestingly enough, these plants are uniquely adapted to pollination by bumblebees, but not in the manner you might expect. The reproductive structures of this Pedicularis are hidden too deeply for a fat bumblebee to reach. In lieu of picking up pollen grains by contact, the bees hover near the flower and the vibrations of their wings causes the pollen to dislodge. Presumably, it is deposited by a similar mechanism as the bees progress from flower to flower.
