1 Sinclair (I.e.: 202) mentioned that the male perianth towards the apex is triangular in cross section, to be seen when the dense indumentum is removed, but I think that this observation rests on an artefact caused by drying; in fact, the bud is not or only faintly angled at the apex. 2 Myristica inopinata is related to M. incredibilis and M. schleinitzii. It may be confused with M. chrysophylla by the conspicuous indumentum of flowers and fruits, but M. chrysophylla has (sub)sessile inflorescences, short pedicelled smaller flowers, and fruits with a thin pericarp.
