I think you may have identified this correctly @MEEJogja. With a name to start with, I found this very nice site called The Tropical Plant Database which I've added to my list! I still don't know about safety for torts.I believe it is some kind of Boerhavia, possibly Boerhavia diffusa. More Commonly found on the Indian subcontinent than here in Indonesia, which is why it wasn't coming up for you @TisMary. The leaves are edible for humans and *probably* for torts too.
