OK, so I guess I will never know since all I have are the labels that came with the cuttings. You are saying the Epi. Oxypetalum will present with only these triangular leaves (are they called three-lobed leaves?) and not flat leaves, right? I can tell you that one of these (flat leaved) plants has already bloomed, a night bloomer, and the flowers looked exactly like those I see posted of the Oxypetalum.
