Purchased this as a seedling about 5 years ago from Sunset Valley Orchids. It is rothschildianum "Dee Dee's Queen" AM/AOS x philippinense var roebelinii. It has a few ruffels in the dorsal and it could use a little more color, but the flowers have a lot of roth influence and they are huge. The natural spread is 20cm and the length of the petals is 20cm. The dorsal measures 4.8cm wide x 6cm tall. The plant has 5 growths with a leaf span of about 2 feet, and it is growing in a 3 gallon nursery container with Orchiata. The flower spike on the left is about 65cm long. It is my strongest growing paph. Mike
