I picked up this guy a few days ago: Correa baeuerlenii
What pollinates them in their native Australia? They look more like they would interest moths, but I'm totally unfamiliar with this plant.
That's a good question and I don't know.
A quick answer is that there are no hummingbird species native to Australia, but there are other nectar-eating birds. From what I can find Correas are generally thought to be bird pollinated (and possibly also by bees?).
Another quick answer is that there is precedent for green (or greenish) flowers being hummingbird pollinated--an example that I found (I assume there are many?) is Passiflora viridiflora. My impression is that many species of Passifloras that are green or white tend to be bird or bat polinated (not counting white color varients/mutants of normally colored species).
My general bias is to think of flowers that dangle on peduncles as being bird (or I guess bat) pollinated. Are insects even capable of sensing motion at a distance?
Did my photo truly get deleted somehow? If so, I've given the link below.
Here is a link that might be useful:
