This one is from Ooi Leng Sun. All Paphiopedilum I got from them are very nice size and healthy although I wouldn't say the same for the other more exotic orchids from them. Here is the
link to my Orchid Borealis blog post with more photos.
The staminode has two horns at the bottom right and left corners. But the illustration in Cribb (1998) doesn't show these. Is it just individual variations?
