I've collected unusual plants for years, and one the fun thing I do on Sundays is play around in my greenhouse. I'll plan on updating this thread occasionally. I hope some of you enjoy these, which is one of the reasons I don't think I would believe in evolution even if I weren't a Christian.
The first is one of our West Coast carnivorous plants, the Cobra Lily
Darlingtonia californica. On the top you can see small clear patches. When an insect flies in the hole at the bottom of the dome, they see the clear patches, or "windows" and bash themselves against them like you see flying insects try to get out of your house by repeatedly hitting a window. The insect eventually falls down the tube, and is used by the plant as food. They grow on very poor soils, where there isn't much competition from other plants, as there are not enough nutrients in the soil to keep plants alive.
The second is
Drosera binata, the Forked Sundew. These plants also live where other plants can't, due to limited nutrients in the soil. This plant has caught a mosquito, and will pull the insect to the center of it's leaf, where specialized cells digest it. They get big enough to catch birds.
