I think it's probably a zamioculcas zamiifolia, apparently often sold as "zz plant". The one I recently bought was labeled "tropical other" with no additional info, but from what I,ve read, it's an aroid, likes medium light levels, warmish temps, and no "wet feet". Mine seems happy outside in dappled shade and since you reminded me, I think I'll go get it out of it's original pot and pot it up a bit.
Also, I did a google search and found images of both single and multiple-stemmed plants.

Cheers and happy gardening, Jeff
