Thank you Cassandra, I assume that's the bottom one?

It does look like a P. bipinnatifidum which usually develops quite a thick stem/trunk. If the stem is fairly fine then it could be P. radiatum, although that is much less common.

Thank you, the truck is getting thicker as it grows so I would guess the common variety. I picked it up for $20 at the local 'Tender Centre' I was very happy. The top one I also paid $20 at the Bundaberg Garden Club Hall sale another bargain.

If you believe the top plant is different it may be Philodendron elegans. The bottom still looks like bipinnatifidum

I do believe they are different as the top one has a clumping habit where as the bottom one has a climbing habit. I’m no expert just trying to learn a bit more.
