This orginally mislabelled plant is flowering again after its first flowering in 2022. By the identification of some members here it is with high probabality a primary hybrid between Paph. supardii x Paph. rothschildianum = Paph. David Ott.
The first flower was already very good ... but the flower of the sibling is even better .... by its form and a deeper colouration (if the photos shows the colour right).
Last time when I thought to flower Paph. barbatum it was a mislabeled plant. This time the plant I bought one year ago is flowering as what has been written on the tag....
Paph. barbatum
Though your Paph. Xanthophyllum is an very old hybrid (registered in 1893) I didn't here of it and havn't seen is so far. I like it due to the intense colouration.
