Paphiopedilum sanderianum STEIN
Occurrence: Borneo, Sarawak, 50 - 900m above sea level, on north-eastern slopes on limestone in humus pockets.
Paph. sanderianum was discovered in 1885 by Forstermann in Borneo. After only a few years in culture and being used in many hybrids, it disappeared again. It was therefore also considered a natural hybrid or monstrosity until it was rediscovered by Ivan Nielsen in Sarawak in 1978.
