Do you have suggestions... Paphiopedilum sanderianum or hybrid with P. sanderianum?

[Suchortomena]

Dear all,

Since around 20 years I cultivate this slipper orchid that I ordered from Popow as a small seedling as Paphiopedilum sanderianum x P. parishii. Within this time there were some ups and downs, but it flowers more or less every three to four years in summer with an inflorescence carrying three to four flowers. This winter an additional inflorescence emerged from a smaller shoot with only one flower and I wanted to take the chance that you can share your opinion with me what this plant might be, as it shows no similarity with P. parishii to me. The leaves are, compared to other Paphiopedilum species, slender, quite long and and the fan grows sideward with leaves hanging down. I cultivate this plant under the roof, in summer quite sunny and hot, now, due to every days cloudy sky, quite shady. The petals are around 27 cm long (very low air humidity now and drying off from the tip).

All the best
Ralph

Here three pictures from my mobile in sunlight.

Not pure sanderianum imho.

 

[Tom-DE]

Not a species sanderianum...and most likely it is correctly labeled--parishii X sanderianum.

 

[Jpari]

I don’t think that this is straight sanderianum. It is most likely a hybrid.

 

[Justin]

Not a sand. sand x praestans or similar is my guess.

Agree that it’s a hybrid. I see what you’re saying about press tans but not enough to make me sure the parishii labeling is incorrect.

Impossible to believe that has parishii in it. All the Sander's Parish I have seen are nothing like that - https://www.slippertalk.com/threads/paph-sander-parish.30588/#post-433479.

I agree with Justin - sanderianum x praestans or sanderianum x wilhelminiae. Here is a photo of the latter (my plant) -

can you show a simple straight on photo of the whole flower?

Here I checked for some older pictures of the same plant. They were taken on May 07. 2009, when I was able to carry the plant down into the garden. Maybe they'll give a better impression how the characteristics are.
