@Junglekeeper, At this stage, after the splits have started to show, if you look at the shape of the splits, the shape of the actual void on Monstera deliciosa is like a long even-width canal with a full half-round termination near the center of the leaf. On a real Split Leaf Philodendron, Philodendron bipinnatifidum (which now also includes P. selloum), the voids between the leaves is not an even long canal but more like a narrowing triangle that comes almost to a point as it approaches the center of the leaf. Also, P. bipinnatifidum have juvenile leaves that are very warped and look almost shredded, not flat and smooth like Monstera. If you were comparing at an earlier juvenile stage, before Monstera get their cut leaves, then they might be mistook for something like a Philodendron cordatum or other smaller vining plants. The Monstera will usually have much longer petioles (leaf stalk that connects the leaf to the stem) and shorter spacing along the stems, which is maybe reversed in the other smaller vines. Also, since these others vines need to be more mature in age to compare to a Monstera juvenile, they will have more evenly sized leaves and the Monstera at pre-cut-leaf stage will have a wide variety of leaf sizes with long petioles and super-short stem sections. These Monstera petioles are also much more upright at this early stage. On mature leaves, Monstera deliciosa seems to maintain plant material all the way out at the very perimeter of the leaves for a more evenly rounded margin (edge), but Philodendron bipinnatifidum has a very jagged appearance, almost like it doesn't have a margin out there. Probably more than you wanted to know! :)
