I am sure this Medinilla but what species could this be?

Have you ever seen blooms on this plant? I wouldn't have recognized it as Medinilla but the leaves do somewhat resemble those of Medinilla (Medinilla scortechinii)

They have some similarities but this plant has a whorled pattern with four leaves each instead of two that are opposite of each other. I don't recall seeing it bloom. I do know that it is epiphytic.

This is a better picture of the plant

Apparently there are several species with whorls of leaves like the one pictured. Hopefully it will bloom so you can get a positive ID.
