According to list, all three reported in Columbia. Noel those dried leaves, when you get tired search for the following on Google maybe you might find some thing fresh.
Philodendron fragrantissimum, Philodendron verrucosum, Philodendron wittianum. The list narrowed it down to these three now its up to you how you proceed further.
