Paphiopedilum x (dayanum x appletonianum) R69T2, April 1969, roll 196904H3 slide 12. From the label, it appears this plant was imported from Thailand in 1969 by Ray Rands, and was regarded as a natural hybrid of Paphiopedilum dayanum and appletonianum. It might be another example of the natural hybrid Paphiopedilum x siamense, but Rands apparently thought he had two different natural hybrids from Thailand that could be distinguished from one another.
