A friend gave me these trees about five years ago. Each was in a small plastic pot. I transferred them to this bonsai pot about three years ago, and the trees have been doing well ... I think. The problem is, I don't know what they are. The leaves are about an inch long, a little stiff, and sticky. The roots grow from a disk-like pod or seed that's around an inch in diameter. It's not a terribly full tree, but I don't know if that's the species or the care. (It stays inside near a north-facing window, gets watered twice/week and fertilized once/month.) I'm also not sure how to cut it or train it, since I'm not sure what it is. (Ignore the small white flowers at the base. They're just decorative.) Can anyone help? Thanks.
