Let's talk about the Philodendron Sodiroi versus the Sodiroi aff.
Growth habit
The true Sodiroi grows vertically versus the aff grows horizontally like a Philodendron Gloriosum.
The sinus and peioles
The Sodiroi sinus, ( which you wouldn't see on a young specimen) but when this leaf unfolds right in the center, it will be red. But on the aff plant it's not red you don't get any of that. The same goes to the petioles, the Sodiroi's petioles are red when is green in the aff.
The lobes
If you look at the lobes for those that are older if you look at the lobes of the leaves it's further apart so the distance between it is very far apart versus the aff is much closer together.
And if you like plants that crawl go for fake Sodiroi one if you like you know extending your moss pole go for the true one. But otherwise, they're kind of similar in some ways, but can you really will see the difference between the two.
