That one is Paph adductum. Paph elliottianum has been considered a synonym to Paph rothschildianum and also as a synonym for Paph adductum when it was discovered in the Philippines. It is probably identical to Paph rothschildianum and there are forms that have yellow or white backgrounds that might have led to such questions as well as importers putting different names on the same species.

Pah eliottianum exists,and is a variant of Paph rothscildianum,I had the luck to see plant in flower in malaysia.The difference is that the petals angle is sharper so are going directly down like in adductum,also colour can be different but cant say cause also in roth there is a huge variety of colours.Unfortunately few years ago I heard that the area where this variety use to grow,burned down compleately,so difficult to say if other\ plants of this variety still grow in the wild.
