This species occurs on the cliffs of the McCluer Gulf and in coastal regions of the Fakfak peninsula.[2] Large subpopulations are now confirmed on Misool.[1][4] Geographer Stewart McPherson had been unable to find any plants during a prior trip to the island (although he did find N. sp. Misool).[2]
Nepenthes treubiana has no known natural hybrids.[2] No forms or varieties have been described.[2]
