I posted the villosum before. Night Song is King Charles x Macabre. Most of the plants are teacup size. There is one which is much larger and the leaves are much darker. Can't wait to see what that one looks like.
A bit more complex than Leyburnense, but very similar. But it looks like Leyburnense is a synonym of Paph Mrs Haywood (acording to the RHS).
Yes, I realiced that it's another hybrid. It's just reminded me of Leyburnense. I loved the red tones, like in yours too. I didn't know about that its synonym would be Mrs Haywood. Maybe it's been given later.
Wössner Orchideen in Germany is still selling some old hybrids like Rosy Dawn, and King Arthur. They have also one named Leyburnense, but I'm a bit doubtful.
Your lowii and haynaldianum are also great. Congrats to all your plants.
