I got this one from Tropical Gardens in Vancouver in bud. What a cutie with small plant structure (leaves less than 10 cm each) with large alba 7-cm flowers (slight damage from transport in check-in luggage). Love the teacup style. Part of my burgeoning alba paphs collection.
I think this one looks very similar to the parent 'Albino Beauty' as posted previously. This shows the consistency of the genes of the parents for size and colour. I have another sib in bud and will compare after in this post.
Concerning my own Albino Beauty-division from Sam...I'm a little worried as it doesn't seem to be in the best of growth... I've been way too busy at work lately, but will inspect it closer next time, I'm watering!
Btw. if the albinistic forms of helenae and barbigerum respectively are the Queen and King of your album collection, I wonder what rank has been ascribed to P. charlesworthii fma. sandowiae? Queen Dowager...or Empress ditto?!
In regards to the alba rankings, charlesworthii fm. sandowiae is the Emperor Charlemagne. He is presently holding court below overseeing the fairrieanum bohlmannianums (aka Fairy Princesses) blossoming.
