Myristica archboldiana is easily distinguishable from other members of the group of species with smaller leaves by its usually cordate leaves that are pubescent below, and its relatively long petiole and the thick-walled fruits. Sinclair (I.e.: 331) suggested a relationship with M. pedicellata and M. tenuivenia on account of the indumentum on the lower leaf surface and mode of venation, but these species have sessile scar-covered inflorescences.
