Thanks everyone! Great pics, Alberto! What show is that from?

I am guessing that flatter petals are more preferred over twisty or "winged" petals (unless they are strangely twisted). This one was fully opened when photographed, and the petals have not turned any noticeable degree. The petal span on this one is 9.6cm, the leaf span about 16cm wide, and the inflorescence being about 25cm long...

I will be making a thread with a comparison of Paph. appletonianum and Paph. wolterianum, showing differences between the two species.
