In this paper an account is given of all names in the genus Myristica Gronov. for New Guinea, including 71 new species, subspecies or varieties and 4 new names either by new combination or new rank. Sinclair (1968) accepted 40 species names with 7 varieties, Foreman (1974, 1978) admitted 45 names (38 species and 8 varieties). In the present census I have 95 species and 31 taxa of infraspecific rank, reflecting a more refined species definition as well as the intensified field collecting of the last decades. A key is given, based on male and female flowering and fruiting specimens.
