Hello everyone, I took all those pictures in Cambodia in May 2018. Photos are not ideal, in many cases there are only leaves. Thank you so much.
Did you only take single leaf photos? Or do you actually have more information, like pictures of the plants that the leaves are from? Leaves by themselves, without seeing the plant shape (even if they are from small plants or from trees) or the arrangement on the stem, are not all that distinctive. The last one could be a Colocasia. 5804 might be Alocasia. First one Syngonium? These are all in the Araceae family.
