This species was first collected in the vicinity of Mount Apo, Mindanao during an expedition led by Schadenberg and Koch in 1882.[2] It was not seen for more than a century and was assumed to be extinct[3] until Pascal Lays found a specimen of this species in South Cotabato in 1994 while studying the Tasaday.[4] A population of this rare Rafflesia species was recently discovered in Baungon, Bukidnon, just outside the buffer zone of the Mount Kitanglad Natural Park in 2007.[1][5] For more information about the remarkable species, see the review in the following citation.[6]

R. schadenbergiana is endemic to the island of Mindanao, Philippines.
