The leaves resemble a peace lily. This one looks like it needs serious pruning. I looked on davesgarden.com and found This
Since it is a tender perennial, a serious trimming will not kill it, but I'd wait til you've watered or soaked it well and allow it to bounce back. Then keep in flourescent or shaded lighting. They love a couple of tablespoons of glycerin mixed with water to help them bloom. I used to trim mine all the way to the dirt surface each spring. I don't think it will root like philodendron but may root if you place a cut trunk with leaves, like shefflera.
