What kind of plant is this?

It came with my tank when I got it, and it has been in there ever since. Whatever it is it's roots are growing. I did a substrate change from gravel to sand, and noticed that the roots had adhered to some gravel. Do you think that the roots will continue to grow in sand? Should I tie it to some driftwood, or will that not work for this plant? 2013-09-15_02-10-22_648.jpg

Hmmm, looks like A. afzelli. You can bury the roots in the sand, just not the rhizome.
