Sorry, I don't know the answer, but DO know it's an Aroid.

I bet if you post this at the Aroid Forum (see top of the front page) you'll get a response.

A bigger and better photo would help too.

dellis, if you click on the picture, it gives you a bigger photo that you can zoom in on.

It looks like your plant may be classified as a Philodendron lacerum. That's the closest looking plant I could find to your own. Good luck!

Drv..how tall is your plant? Looking at the last leaf, it reminds me of a P. Selloum or P. Xanadu.

It could pass for P. Lacerum, but the veins on Lacerum are more pronounced than your plant.

I agree, bet it's going to be a big guy, and will eventually need staking. Toni
