Ptychosperma is a genus of flowering plant in the family Arecaceae. Most are native to Australia and/or New Guinea, with a few in the Solomon Islands and in Maluku Province of eastern Indonesia. Some have been cultivated abroad as house or garden plants, and reportedly naturalized in certain regions (Caribbean, Polynesia, Fiji, Florida).[1][2]
