Paph Eva Weigner (stonei x haynaldianum)
This hybrid was registered in 1980 by the Orchid Loft, although I believe they registered the reverse cross (haynaldianum x stonei).

I hope you enjoy these photos of my Paph Eva Weigner; pictures of hybrids such as this one are not always easy to find.

Below are some photos of the bloom in various stages of development.
