There’s a new plant wiki in town, Plants.am – Plant Encyclopedia and Gardening Wiki.
Venus Flytrap. Nope, page doesn’t exist yet. Maybe you could fill them in?
Cactus. Well, that’s interesting. The page starts off by borrowing photos and text from Wikipedia.
I see some differences there. Just not a lot. But then, it’s a new site. More will come, I’m sure.
