I researched this Phaius because I didn't know the parents and found out two things- Micro Burst is two words (couldn't get any results with one word), and instead of a Phaius, it's a Gastrophaius (Gastrorchis pulchra x Phaius tankervilleae). The original must have been registered with Phaius pulcher, which is a synonym for Phaius pulchra. I learn something new every day.
