Here are some pics of Philodendron domesticum - it looks very similar (this was called Lemon Lime). It has a few variations. But this one looks like it might be it.
Yes dean, I too think so. Lemon lime is a beautiful name for this ever fresh climber/spreader. My plant has a much light shaded young leaves and gives a superb light-dark lemon green color play. I love to keep it potted inside my chamber.
