This was, I believe,intended as a bonsai. It lived in a jar that was so tight I had to break it to get the little tree out (so I could repot it.)
The bulbous base doesn't show extremely well in the photos, but it is quite round and large compared to the stem(s).
The leaves look like ficus of some kind? (There is a little rubbertree ficus elastica sprout coming out near the base but it is a volunteer seedling from a large plant that was close by to this one for a long time.)
Anyone know this plant? I feel sure I have seen pictures of similar bulbous-based tree-like houseplants but can't think of where.
