Ursula, why do you think the Phal. is a lobii? How can you tell the difference? I see what you mean from the Orchid Species photo, but my reference photos show that yours looks identical to parishii.
Maybe the plant form and not the flower has clues. I'd think twice before relabeling.
This Tolumnia is currently a NOID. I'm hoping to catch the name when the next shipment comes in.
