This species might only represent a cultivar or cultivar group descended from the wild species Pandanus brosimos. Another relative, andanus iIwen, which is reported to be cultivated in Papua New Guinea, might only be a cultivar of the so-called Pandanus brosimos/julianetti complex. The whole needs taxonomic revision[].
