Notes
1 The sepals in the few male flowers available for study are remarkably different: those of Docters van Leeuwen 9873 (West Papua) are narrow and only c. 0.5 mm long; those of Ridsdale NGF 30335 (Papua New Guinea, Morobe Distr.) are broad and rounded and c. 2 mm long; those of the other 3 collections are ± intermediate. In Docters van Leeuwen 9873 possibly a small depressed central disc is present, but this cannot be determined with certainty; however, a disc is absent in the other specimens.
2 According to molecular phylogenetic analyses Papuasicyos is congeneric with Urceodiscus ().
