I also finished a thing:http://imgur.com/a/zAM6a
Note that I often included the entire group, even if only some species were cultivated. This is because if you look at some of the wild forms it's easily imaginable that similar plants can be cultivated as well. Just look at wild maize.
Also, I purposefully left out cacao and coffee. Both are luxury goods more than anything and can be substituted easily. While the same could be said for cannabis and tobacco, they are a bit more specific that you'd have a hard time supplanting them with something else. Having that said, I mostly included them for kicks and giggles. :P
