Paramyristica sepicana much resembles some species of Myristica from New Guinea. Because of its papillose leaf undersurface it would key out in the genus Myristica beside M. ornata. However, it does not at all resemble the latter in habit or in fruit. The present species seems rather more related to M. markgraviana, M. carrii, and M. hooglandii, all with a similar androecium and, indeed, in habit approaching the latter two species. For differences between Myristica and Paramyristica, see De Wilde (I.e.: 344-347).
