Paph Pink Sky was registered in 1995 as (Lady Isabel x delenatii) by O. Viengkhou. Lady Isabel is (rothschildianum x stonei) which was registered in 1897. The picture below came from a remake of the cross by Orchids Limited, done as the reverse cross (delenatii x Lady Isabel ‘Princess Irene’).

Others can speculate on the difference it might make to have delanatii be the seed parent instead of the pollen parent. In the following link, Robert Jan-Quene (Drorchid) posted in Slippertalk 3/06/2009 about new Pink Sky crosses by Orchids Limited:

I can’t be sure if my plant came from the same cross that Robert posted, but I have had this plant for a handful of years. It has bloomed about every other year for me. It had a little fight with mealybugs a year ago which slowed it down, but now it seems to be picking up.
It is a fairly compact plant for me. The NS (horizontal) of the petals is 15 cm. The color is darker than I have had before, with the stripes on the dorsal more distinct. This may relate to the spike developing during the “winter” period in my indoor plant room during which day length is 11 hours and the temperature is a maximum of 70 degrees F day and nights are 55 degrees F. During this period I water less frequently with low concentration of fertilizer. This hybrid blooms for months without much change in coloration.
Probably the most famous delenatii x (polyantha division) cross was Delrosi, registered in 1961 as (delantii x rothschildianum) but this cross seemed to give many growers fits trying to bloom. Delanatii was also crossed with other polyantha Paph. species but they don’t seem to have become widespread. Maybe they are also difficult to grow.
Robert’s post reflects the hope that newer generation rothschildianum (or other primary polyantha crosses like Lady Isabel) would create faster growing and blooming hybrids when paired with parvisepalum species. However, I have not seen many delenatii x polyantha crosses posted on Slippertalk.
