Başlangıçta gelen, Papua New Guinea

Ptychococcus lepidotus is a palm of montane rainforest, at 760-1620 m in elevation. Ferrero (1996) gave 3000 m as the upper limit in elevation. Hay (1984) said that it was a common element of the lower montane rainforest dominated by Castanopsis (D. Don) Spach, in the vicinity of Bulolo. Its natural distribution corresponds to central Papua New Guinea, but it is widely cultivated and perhaps moved about by humans. The only known specimen from Indonesia was taken from a cultivated plant. It is not known to occur naturally in Indonesia.
