You are very welcome!* Your picture is so small I can't see it even when I put it on my 'puter and enlarge it.* It just blurrs.* Your pic is 80 x 80.* Try something like 700 x 700 for size and go smaller by increments.*
If you were able to look at the sites I sent you, you would note there are self-heading philodendrons that don't vine, but send out air roots for support when the plants get some age and height to them.* They grow more like a tree.
Here's some interesting info on Philodendron leaf size and shape.
Here's the main page that talks about everything related to them, including air roots.* You can even click on #6 for 'Selected Species' and do a google image search for each name if you like.* You may not always see mature leaves in your search.
There are Alocasia that get large leaves, but these grow from tubers like a potato and I've not found any info on them that says they get air roots.* Again, without a better picture of the first one you posted, it's difficult to say.* Try the size I suggested to see if that works better.
When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.
