According to Robert Ang blog, it's is R155 Phal Soo Ngor - Phal Gladys Fang x Phal violacea 'Alba'.
Somewhere in the middle, highlighted in RED. Eucharist Orchids
I have seen this discrepancy before, but if you were to look up Gladys Fang and Brother Trekkie are the same hybrid, somehow registered with different names. In regards to the "r" being absent in the RHS, your guess is as good as mine. Otherwise, I LOOOVE it!!!!
