Myristica inaequalis is provisionally reckoned to the group with larger leaves (blade length 15 cm or more) and subsessile or short-stalked inflorescences (as in Knema). It keys out next to M. fusca (to which it is closely related). The caducous bracteole, situated about halfway on the pedicel, is reminiscent of that of M. mediovibex from about the same area.
