Wow! Look at all that species influence! But it's amazing that it's as hybridized as it is. It's not even dominated by a single species.
Phal amabilis x aphrodite = Phal Bataan
Phal Bataan x lueddemanniana = Phal Star of Rio
Phal Star of Rio x amboinensis = Phal Samba
Nice one, Steven! As for the spike, I'd leave it on unless the leaves look really stressed. It's pretty, it may keiki, and the plant may be able to support the flowers despite the root problem. If the leaves start looking tired and yellow, I'd jettison the spike and stick in a vase. You'll get another week or two of enjoyment.
