Monkey Orchids

If you’re anything like me, you would love the Facebook group I Fucking Love Science. It updates many times per day, and I subscribe to it via RSS feed to make sure I don’t miss any posts (and to keep myself from logging onto Facebook more than once per day). If not for IFLS, I would not have known about monkey orchids, which are my new favorite plant. They shared this photo (compiled by another Facebook group, Beware of Images) of Dracula simia (the little monkey faces) and Orchis simia (the little dancing monkeys):

I’m trying to decide which monkey the faces most resemble. A guenon? Leontopithecus? Pithecia?
