Meet Fabiana

Meet Fabiana, my new cactus (?) that I bought at the Illegal Pickpocketer's Haven (or "shouk") this past Sunday, quite possibly the only legit purchase that could be made:

Does anyone out there know if this truly is a cactus, and if so, what kind? I've been searching for it on cactophile sites, but it seems there are just too many species to go through.

[Update] So, apparently its a Jade plant. I guess I'll still have to get a real cactus from the sellers in the campus center.
