Berasal dari, Papua New Guinea, Indonesia

Ptychococcus paradoxus is a palm of lowland rainforest or alluvial forest, often over limestone, at 0-850 m in elevation. The palm often grows in very wet or swampy habitats, sometimes in association with Metroxylon sagu, or along riverbanks or in flood plains. It is widespread throughout lowland New Guinea, although much of its present range may be due to distribution and cultivation by humans.
