Had the same question a while ago. Here's what came up on my thread about that plant.

If you are into taxonomy then look at the link on the bottom of the first page.
That being said, it is a great vivarium plant and has done really well for me. I keep it as a houseplant, in vivariums, and have even have some cuttings that have been kept in just tap water for about five months (and have started cuttings from these cuttings!).
